Mulheres Que Mudaram o Mundo
Ada Lovelace
Ada Lovelace, born Augusta Ada Byron on December 10, 1815, is widely recognized as the first computer programmer in history, despite having lived long before the advent of modern computers.
The only child of the famous British poet Lord Byron and Anne Isabella Milbanke, Ada inherited an unusual legacy: while her father was a prominent figure in the world of romantic literature, her mother, Anne, had a strong interest in science and mathematics.
It was her mother, after separating from Byron a few months after Ada was born, who decided to raise her daughter away from her father's poetic influence, focusing on a scientific and rational education.
From a very young age, Ada demonstrated an exceptionally creative and curious mind, with a great aptitude for mathematical sciences. Her mother encouraged her to study with the best tutors of the time, including the renowned mathematician Augustus De Morgan.
Despite living in an era when the study of sciences was predominantly male, Ada stood out for her passion and dedication.
Ada Lovelace's most notable contribution to the history of science came when she began working alongside mathematician and inventor Charles Babbage, who created one of the first designs for a mechanical computer, called the "Analytical Engine."
In 1833, Ada met Babbage at a party, and the two quickly formed an intellectual friendship based on shared interests, particularly in the fields of mathematics and technological innovations.
Babbage had already designed an earlier machine, known as the "Difference Engine," designed to solve complex mathematical equations, but it was his "Analytical Engine" that caught Ada's interest. This machine was much more advanced and was considered the precursor to modern computers, since, in addition to performing calculations, it had the ability to be programmed to perform different tasks.
In 1843, Ada was invited to translate an article by Italian mathematician Luigi Menabrea, which explained how Babbage's Analytical Engine worked. But Ada went further: not only did she translate the article from French into English, but she also added her own detailed notes, which ended up being three times longer than the original text.
These notes became known as “Ada Lovelace’s Notes,” and are considered the first description of an algorithm designed specifically to be processed by a machine, making Ada Lovelace the first computer programmer in history.
What set Ada Lovelace apart from other scientists of the time, including Babbage himself, was her futuristic view of the potential of computing. While Babbage saw his Analytical Engine as a device designed to perform mathematical calculations, Ada imagined that it could be used for much more than that.
She believed that, if properly programmed, the machine could process not just numbers, but any type of information, such as text, images, and even music.
Ada envisioned in her notes that one day similar machines would be able to perform creative tasks, such as composing music or creating art, an incredibly advanced vision for her time.
This innovative perspective was one of Ada Lovelace’s greatest contributions to computer science. She was able to see the true potential of a programmable machine, something that would not be fully understood until more than a hundred years later with the advent of modern computers.
Unfortunately, Ada Lovelace did not live long enough to see the impact of her ideas. She died young, at the age of 36, on November 27, 1852, from uterine cancer. Her scientific contributions remained largely forgotten for the next century, until her notes were rediscovered in the early 20th century and recognized as fundamental to the development of modern computing.
Today, Ada Lovelace is revered as a pioneer in computer science and an inspiration to women and girls around the world pursuing careers in science, technology, engineering, and mathematics (STEM). “Ada Lovelace Day,” celebrated annually in October, is dedicated to celebrating the achievements of women in science and technology.
Her name was also immortalized in the programming language “Ada,” developed by the United States Department of Defense in the 1970s. This honor underscores her importance as the first person to realize the true potential of a programmable machine and the first to write an algorithm designed to be executed by a machine.
Ada Lovelace was a woman ahead of her time. Her collaboration with Charles Babbage and her “Notes” on the Analytical Engine laid the foundation for the development of the computers we use today. Her vision that machines could be more than mathematical calculators was revolutionary and paved the way for modern computer science.
In addition to her scientific contributions, Ada Lovelace's legacy serves as a powerful reminder of the lasting impact women can have on the advancement of science and technology.

Ada Yonath
Ada Yonath was born on June 22, 1939, in Jerusalem, then part of the British Mandate of Palestine (now Israel). She grew up in a modest environment within an Orthodox Jewish family and showed an early passion for learning. Despite financial difficulties, her curiosity for science drove her to pursue a solid education.
She studied at the Hebrew University of Jerusalem, earning a degree in Chemistry and Biochemistry in 1962. She then completed her master’s and Ph.D. at the Weizmann Institute of Science, specializing in X-ray crystallography, a technique used to determine the three-dimensional structure of complex molecules.
After obtaining her Ph.D. in 1968, she conducted research at prestigious institutions such as the Massachusetts Institute of Technology (MIT) and Carnegie Mellon University.
Throughout her career, Yonath dedicated herself to studying the structure of ribosomes, the cellular organelles responsible for protein synthesis.
Her goal was to understand how these structures function at the atomic level, which could have significant medical implications, particularly in developing new antibiotics.
During the 1980s, Yonath faced significant challenges in trying to crystallize ribosomes for X-ray analysis. Many scientists at the time considered this task impossible due to the complexity and fragility of ribosomes.
However, her persistence led to the development of innovative experimental methods that allowed for the detailed imaging of bacterial ribosomes.
Her work significantly advanced the understanding of antibiotic resistance, aiding in the development of more effective treatments against bacterial infections.
In recognition of her groundbreaking discoveries, Ada Yonath was awarded the 2009 Nobel Prize in Chemistry, becoming the first woman from the Middle East and the first woman in over 45 years to receive the award in this field. She shared the prize with Venkatraman Ramakrishnan and Thomas Steitz.
Beyond her research, Yonath is known for advocating science as a tool for peace, encouraging collaboration between scientists from different countries, including Israel and Arab nations. She continues her work at the Weizmann Institute of Science, leading research on ribosomes and their medical applications.
Ada Yonath remains an inspiration to scientists worldwide, particularly women in STEM. Her determination and revolutionary contributions continue to impact molecular biology and pharmacology, demonstrating how perseverance and innovation can transform our understanding of life.

Adriana Oliveira Melo
Adriana Suely de Oliveira Melo is a Brazilian physician specializing in fetal medicine who gained worldwide recognition for her pioneering work in establishing the link between the Zika virus and microcephaly.
A graduate of the Federal University of Paraíba (UFPB), Adriana is known for her commitment to maternal and child health and her dedication to research and clinical care.
In 2015, when the Zika outbreak spread throughout Brazil, Adriana began to observe a significant increase in cases of microcephaly in newborns, especially in the state of Paraíba.
As an ultrasound specialist, she was one of the first professionals to document the relationship between the Zika virus during pregnancy and severe brain anomalies in fetuses.
This work, published in the Lancet journal, was essential in alerting health authorities and the international scientific community about the impact of the epidemic.
In addition to her clinical and research work, Adriana also works to train other professionals and support affected families.
She founded initiatives focused on monitoring children with microcephaly, offering multidisciplinary treatments that include physical therapy, speech therapy and emotional support for families.
Her work has transcended Brazil, helping to raise awareness about the prevention and management of Zika-related conditions in other countries.
Despite the challenges faced, including the lack of consistent investment in scientific research in Brazil, Adriana continues to be an advocate for public health, especially in the care of vulnerable children and their families.
Her work has received national and international recognition, making her an essential figure in combating the consequences of the Zika virus and other neglected diseases.
She currently also serves as president of the Professor Joaquim Amorim Neto Research Institute (Ipesq), a non-profit, philanthropic civil organization founded in 2008 in Campina Grande, Paraíba.
The institution combines comprehensive care for patients and their families with the promotion of scientific research on the long-term consequences in children with microcephaly and congenital Zika syndrome.
Its interdisciplinary team adopts the action-research methodology to improve understanding of the disease and improve care for the needs of patients and their families.
In the area of care, it offers comprehensive support for the needs of patients and their families with physiotherapists, neuropediatricians, pediatricians, speech therapists, among others - which enables a comprehensive view of each case and the definition of procedures.
Up until its inauguration, approximately 125 children were being treated, but the trend is for this number to increase due to the demand from patients from other cities.

Agnes Pockels
The history of science is filled with figures whose contributions transformed our understanding of the world, yet many remain relatively unknown. Among them is Agnes Pockels (1862–1935), a self-taught scientist who revolutionized the study of surface tension and liquid properties, paving the way for modern surface science.
Despite lacking formal university education, Pockels developed innovative methods to study interfacial phenomena, becoming one of the first to quantitatively measure the surface tension of water and other substances.
Agnes Luise Wilhelmine Pockels was born on February 3, 1862, in Venice, then part of the Austrian Empire, but spent most of her life in Braunschweig, Germany. Her father, a military officer, had a keen interest in science, particularly physics, which sparked Agnes's curiosity from an early age.
However, in 19th-century Germany, women were not allowed to attend universities. While her brother, Friedrich Carl Pockels, was able to study physics and become a professor, Agnes was denied a formal education in science. Nevertheless, this did not stop her from pursuing research.
Self-taught, she studied physics and mathematics using her brother’s books and conducted experiments in her home kitchen.
Despite societal limitations, Pockels became a pioneer in thin-film studies and surface tension, laying the foundation for modern surface and colloid chemistry.
Curious about how water interacted with oils and other substances, Pockels noticed that contaminants influenced surface tension. To investigate these interactions, she developed a rudimentary device in her kitchen, later known as the "Pockels Trough". This instrument consisted of a water-filled tray on which she spread substances, using a sliding ruler to measure how they altered surface tension.
This innovation was the precursor to the Langmuir balance, later invented by Irving Langmuir and Katharine Blodgett, who formalized the theory of molecular monolayers on water surfaces.
Lacking direct academic connections, Pockels initially kept her discoveries private. However, in 1891, she wrote a letter to British physicist and chemist Lord Rayleigh (Nobel Prize in Physics, 1904), describing her experiments and measurements. Impressed, Rayleigh forwarded Pockels’ work for publication in the prestigious scientific journal Nature.
Her article, titled "Surface Tension", was published in 1891, making it one of the first quantitative studies on interfacial interactions in liquids. This publication brought Pockels recognition in the international scientific community.
Pockels’ studies paved the way for advances in multiple fields, including:
Surfactant chemistry – Understanding substances that alter water’s surface tension, crucial in detergents and cosmetics.
Biophysics – Insights into lipid organization in biological membranes.
Nanotechnology – Applications in thin films and nanomaterials.
Today, the concepts introduced by Pockels remain fundamental in disciplines such as colloid science, chemical engineering, and molecular physics.
Despite gaining academic recognition, Agnes Pockels never held an official position in any research institution. She continued her studies independently, publishing several papers on interfacial liquid properties.
In 1932, she was awarded the Laura R. Leonard Medal by the Society of Industrial Chemists of London, one of the few honors she received in her lifetime.
Pockels passed away in 1935, but her legacy endures. Her work laid the groundwork for future research and directly influenced scientists like Irving Langmuir, who expanded on her discoveries and won the 1932 Nobel Prize in Chemistry for studies on molecular monolayers on liquid surfaces.
Agnes Pockels is an inspiring example of determination and passion for science. Even without formal access to academia, her curiosity and ingenuity led to fundamental discoveries in surface chemistry.
Her pioneering work not only established a new scientific discipline but also challenged gender barriers in a time when women were systematically excluded from science.
Today, her name is honored in scientific awards and physical chemistry laboratories, reaffirming her importance as one of the great scientists of the 19th century.

Alice Alldredge
Alice Alldredge is a renowned American oceanographer celebrated for her groundbreaking contributions to marine ecology, particularly in understanding biogeochemical processes in the ocean's water column.
She earned her biology degree from the University of Nebraska and completed her Ph.D. in biological oceanography at Harvard University.
Alldredge discovered the existence of abundant gel particles called Transparent Exopolymer Particles (TEP) and demersal zooplankton, describing their migration and dispersion throughout coral reefs, seagrass meadows, and tidal sandflats.
From the outset of her career, Alice was deeply interested in how marine organisms interact with global carbon cycles, becoming one of the pioneers in studying what is now known as “marine snow.”
Her most acclaimed work focused on the study of marine snow, aggregates of organic and inorganic particles that slowly sink from the ocean surface to the deep sea.
Alldredge demonstrated how these aggregates play a crucial role in the biological carbon pump, transporting carbon from surface waters to the deep ocean.
This work transformed scientific understanding of natural carbon sequestration and the ocean’s role in regulating Earth's climate.
Throughout her career, Alice also studied protists and marine microorganisms, revealing how these microscopic life forms influence the structure and functioning of pelagic ecosystems.
Her findings contributed to the refinement of oceanic ecological and chemical models, with direct implications for climate modeling and marine resource management.
In addition to her scientific achievements, Alldredge has received numerous awards for excellence in research and teaching.
She has been honored by the American Geophysical Union and the Association for the Sciences of Limnology and Oceanography, and she is a member of the U.S. National Academy of Sciences.
As a longtime professor at the University of California, Santa Barbara, she has mentored generations of oceanographers and marine biologists and is widely regarded as an exemplary mentor.

Alice Ball
Alice Ball was a brilliant and pioneering chemist who made significant contributions to medicine, especially in the treatment of Hansen’s disease (also known as leprosy).
Born on July 24, 1892, in Seattle, Washington, Alice Augusta Ball rose to prominence at a time when women, especially black women, faced significant barriers in academia and science.
Alice Ball had a solid upbringing. Her family was relatively well-educated, and her grandfather was a famous photographer, which contributed to a stimulating intellectual environment.
She graduated with a degree in pharmaceutical chemistry from the University of Washington in Seattle in 1912. Ball later decided to continue her education and earned a second degree in pharmacology.
Ball moved to Hawaii to pursue her master’s degree in chemistry at the University of Hawaii. It was there that she began working with chaulmoogra oil, which at the time was a treatment for Hansen’s disease. However, the oil was ineffective when applied externally and difficult to administer when ingested or injected.
Alice Ball’s greatest achievement was developing a method to transform the active components of chaulmoogra oil into a form that could be easily injected and absorbed by the body.
This method, known as the “Ball method,” made a huge difference in the treatment of leprosy, a stigmatized disease that caused great suffering.
Her solution allowed patients to receive treatment without the severe side effects associated with the oil in its original form.
Unfortunately, Alice Ball did not experience the full impact of her discovery. She tragically passed away on December 31, 1916, at the age of 24, before completing her doctorate and before her treatment was widely recognized.
For years, Ball’s work was erroneously attributed to Arthur L. Dean, who continued her research after her death.
Decades after her death, Alice Ball began to receive the recognition she deserved. In 1922, six years after her death, her work was finally officially recognized.
In 2000, the University of Hawaii honored her by placing a plaque in her honor. In 2007, the then-governor of Hawaii declared February 29 “Alice Ball Day,” a tribute to her remarkable scientific contributions.
Alice Ball left a lasting legacy, not only for her scientific innovation, but also as a pioneer for women and people of color in science.
Her work saved thousands of lives, and her name is now recognized as synonymous with perseverance and genius in the fields of chemistry and medicine.
Her story highlights the essential contributions that women, often marginalized, have made to the advancement of science, and her memory continues to inspire future generations of scientists.

Alicia Dussán de Reichel
Alicia Dussán de Reichel was born in Bogotá in 1920 and became one of the first female pioneers in Colombian academia.
In 1941, she joined the newly established Instituto Etnológico Nacional, founded by Paul Rivet, shifting from law to anthropology and archaeology.
As a member of Colombia’s first generation of ethnologists, she faced significant challenges as a woman in a male-dominated field .
Working alongside her husband, Gerardo Reichel-Dolmatoff, she conducted groundbreaking expeditions across Colombia: studying funerary urns from the Magdalena River region, discovering some of the oldest ceramics in the Americas at Puerto Hormiga and Monsú, and researching indigenous cultures in the Caribbean, Pacific, and Andean regions.
Their work contributed to the legal recognition of indigenous reserves and led to creating institutions like the Instituto Etnológico del Magdalena and involvement in Bogotá’s Gold Museum.
In 1963, Alicia co-founded Colombia’s first Anthropology Department at Universidad de los Andes and taught until 1968.
She also pioneered gender studies and urban anthropology, researching housing and rural-urban migration.
Later, she served as advisor for the Gold Museum installation, headed the Division of Museums and Restoration at the Ministry of Culture, and held positions at museums in the U.S, including Los Angeles.
A prolific author with over 50 articles and dozens of books, 23 co-authored, Alicia contributed extensively to museology, indigenous ethnology, and archaeology.
Renowned for her bravery, generosity, and leadership, she received numerous honors like the National Award for Life and Work (2001), French decorations, and an honorary doctorate.
She passed away in May 2023 at age 102, leaving a legacy as a trailblazer in anthropology and an inspiration for future generations.

Andrea Ghez
Andrea Ghez is a renowned American astronomer and physicist, known worldwide for her groundbreaking contributions to the study of supermassive black holes.
Her pioneering work led to the confirmation of the existence of a giant black hole at the center of the Milky Way, a feat that earned her the Nobel Prize in Physics in 2020.
Her career is an inspiring example of perseverance, passion for science, and advancement in the field of astrophysics.
Andrea Mia Ghez was born on June 16, 1965, in New York City, United States. From an early age, she showed great interest in space and science.
Her main inspiration was the space race between the United States and the Soviet Union, especially the NASA missions that took man to the Moon.
This fascination with the universe led her to dream of becoming an astronaut, but throughout her education, she realized that her true passion was understanding the mysteries of the cosmos through astronomy.
She entered the Massachusetts Institute of Technology (MIT), where she graduated in Physics in 1987. She later went on to the California Institute of Technology (Caltech), where she completed her doctorate in 1992.
It was during this period that she began to develop her research on the center of the Milky Way, a topic that would define her scientific career.
After obtaining her doctorate, Ghez became a professor and researcher at the University of California, Los Angeles (UCLA).
Her main goal was to investigate what existed at the center of our galaxy, an extremely dense and obscure region.
Many scientists suspected the presence of a supermassive black hole, but proving its existence was a huge challenge.
To do this, Ghez used the most advanced astronomical observation technologies.
She used the Keck Telescope, located in Hawaii, which has one of the largest optical mirrors in the world.
However, observing the center of the galaxy was difficult due to Earth's atmospheric turbulence, which distorted the images.
To get around this problem, Ghez and his team applied the adaptive optics technique, which corrects these distortions in real time and allows for much sharper images of space.
Through decades of observation and detailed analysis of the movement of stars near the center of the Milky Way, Ghez was able to demonstrate that they orbited an invisible point at an extremely high speed.
The only possible explanation for this phenomenon was the presence of a supermassive black hole, with a mass equivalent to about 4 million times that of the Sun.
This work was fundamental to modern astrophysics, as it provided the most direct evidence ever obtained for the existence of supermassive black holes in the universe.
In 2020, Andrea Ghez was one of the laureates of the Nobel Prize in Physics, together with Reinhard Genzel and Roger Penrose.
She became the fourth woman in history to receive the Nobel Prize in Physics, following in the footsteps of Marie Curie (1903), Maria Goeppert-Mayer (1963) and Donna Strickland (2018).
In her acceptance speech, Ghez highlighted the importance of encouraging more women to enter science and pursue careers in physics and astronomy.
Her career has become a reference for future generations of scientists, especially for women who wish to work in fields dominated by men.
In addition to her discoveries about black holes, Andrea Ghez continues to lead research on the phenomena of the galactic center and participates in several scientific projects.
Her work has helped pave the way for new studies on general relativity, the dynamics of galaxies and the evolution of the universe.
She also plays an active role in scientific outreach, participating in educational programs and encouraging young people to become interested in astronomy.
Her impact goes beyond academic research, influencing the way we understand the universe and inspiring future generations of scientists.
Andrea Ghez not only solved one of the greatest mysteries of the cosmos, but also proved that dedication and passion for science can lead to extraordinary discoveries.
Her work on supermassive black holes changed our understanding of the universe and secured her place among the greatest scientists in history.
Her legacy continues to grow, fueling new explorations and inspiring scientists around the world to look to the stars for answers.

Ann Burgess
Ann Wolbert Burgess, an iconic figure in criminology and forensic psychology, is widely recognized for her pioneering work in understanding the behavior of sex offenders and developing practices for investigating violent crimes.
Burgess was born in 1936 and began her career in the field of psychiatric nursing. Her life and career unfolded at a time when little was known about the profiles and psychology of sex offenders and serial killers.
She devoted herself to studying the impact of violent crimes, such as rape and sexual assault, on victims and developing data-driven intervention models to combat these types of crimes and support traumatized victims.
Ann Burgess earned her bachelor’s degree in nursing from Boston University and then specialized in psychiatric nursing.
She continued her education, earning a master’s degree from the University of Maryland, followed by a doctorate in psychiatric nursing from Boston University.
In the 1970s, early in her career, Burgess became interested in the effects of violent crime and how trauma affected victims, an area that was largely unexplored at the time.
She co-founded a rape crisis program in Boston, which became one of the first centers to offer specialized psychological treatment and support. Her early research on post-crime trauma was instrumental in defining what would later become known as Post-Traumatic Stress Disorder (PTSD).
In the 1970s and 1980s, Ann Burgess was invited by the FBI to collaborate with agents in the agency’s Behavioral Science program. This collaboration resulted in the development of the “psychological profiling” method of criminals, which focused on studying the behavior and patterns of serial killers and other violent criminals.
Working alongside notable agents such as John E. Douglas and Robert Ressler, Burgess helped create a systematic methodology for understanding criminals’ motivations and modus operandi, which came to be known as criminal profiling.
This collaborative work formed the basis for what we now know as “criminal profiling” and influenced the creation of specialized behavioral analysis divisions within the FBI. The method she helped develop remains standard practice in criminal investigations. Her collaboration with the FBI also inspired the Netflix series “Mindhunter,” which features a character inspired by Burgess.
Burgess has published extensively on sexual assault, psychological trauma, and forensic psychology. Her books include “A Field Manual for Investigating Violent Crime Cases” and “Sexual Homicide: Patterns and Motives,” which she co-wrote with Douglas and Ressler, as well as “Victimology: Theories and Applications.” These books are widely used resources for mental health professionals, law enforcement, and academics in the field of criminology.
She has also conducted significant studies on child abuse, domestic violence, and cybercrime. In her publications, Burgess frequently emphasizes the importance of addressing victims’ psychological trauma and improving investigative techniques to better protect communities and prevent future crimes.
Throughout her career, Ann Burgess has been widely recognized and awarded. She has received the American Nurses Association Hildegard Peplau Award for Excellence in Psychiatric Nursing, among other awards. Her dedication and the changes she has promoted in the field of criminology, forensic psychology, and nursing have earned her a respected position in the scientific and academic community.
Ann Burgess remains active in the field of criminology and forensic nursing, continuing to teach and contribute to research.
Her career is marked by a dedication to understanding the criminal mind and developing more effective practices for treating and protecting crime victims.
Burgess’s work shaped the way law enforcement and mental health professionals approach crime and trauma, making her impact on criminology and forensic psychology a lasting one.

Anne McLaren
Anne McLaren was one of the most influential geneticists of the 20th century, known for her pioneering research in assisted reproduction and embryonic development.
Her work paved the way for scientific advances that led to in vitro fertilization (IVF), helping millions of people around the world have children.
In addition to her scientific contributions, McLaren was also a tireless advocate for ethics in genetic research and the role of women in science.
Anne Laura Dorinthea McLaren was born on April 26, 1927, in London, United Kingdom.
Her father, Sir Henry McLaren, was a member of the House of Lords, and her mother, Christabel McNaughten, was an educated and progressive-minded woman.
During her childhood, Anne showed an interest in science, and in biology in particular.
During the Second World War, her family moved to Wales to escape the bombings of London.
It was there that McLaren began to develop an even greater interest in the natural world, observing wildlife and developing a scientific curiosity that would stay with her for the rest of her life.
After the end of the war, she entered the University of Oxford, where she studied zoology at Lady Margaret Hall.
During her undergraduate and doctoral studies, she worked under Peter Medawar, an immunologist who would later win the Nobel Prize.
Her doctorate focused on the developmental embryology of mice, a field that was still relatively new at the time.
After completing her doctorate, McLaren began working at the Institute of Animal Genetics at the University of Edinburgh in Scotland.
It was there that she began groundbreaking experiments to understand the development of mammalian embryos, using mice as a model.
In the 1950s, together with John Biggers, she performed one of the most important experiments in the history of reproductive biology: for the first time, mammalian embryos were grown in a laboratory environment and then successfully transferred into the uterus of a female.
This pioneering work demonstrated that it was possible to manipulate embryos outside the mother’s body and re-implant them, a fundamental principle in the development of in vitro fertilization.
This discovery was a watershed in reproductive science and paved the way for the successful use of IVF in humans years later.
The first baby conceived by IVF, Louise Brown, was born in 1978, and this breakthrough was only possible thanks to the scientific foundations laid by McLaren and her colleagues.
In the 1960s and 1970s, McLaren continued her research in embryology and reproductive genetics.
Her work expanded to understanding how embryos develop and how genes influence this process.
She also became interested in the study of embryonic stem cells and was one of the first scientists to suggest that these cells might have future medical applications.
She also contributed to research into cloning and genetic manipulation of embryos, raising questions about the ethical and scientific challenges of these techniques.
During her career, McLaren worked at several leading scientific institutions, including the Royal Society, the Institute of Reproductive Biology and the Wellcome Institute of Reproductive and Cell Biology.
In addition to her impact on science, McLaren stood out as a strong advocate for ethics in genetic and reproductive research.
As assisted reproductive technologies advanced, she advocated for the responsible use of these techniques and participated in debates on bioethics, warning of the dangers of indiscriminate use of genetic manipulation.
She also fought for the recognition and inclusion of women in science.
As one of the few women in her field at the time, McLaren faced barriers and prejudice, but managed to build a brilliant career and became a role model for future generations of scientists.
She was the first woman to hold a position on the board of the Royal Society, one of the most prestigious scientific institutions in the world.
Her work helped open doors for other women in science, encouraging policies to increase female participation in fields such as genetics, biology and medicine.
Throughout her career, Anne McLaren received numerous honors for her contributions to science, including:
- Dame Commander of the Order of the British Empire (DBE), awarded in 1993, for her impact on reproductive biology.
- Royal Medal from the Royal Society, one of the United Kingdom’s highest scientific awards.
- President of the Genetics Society of the United Kingdom.
- Election as a Fellow of the Academy of Medical Sciences and the National Academy of Sciences of the United States.
Her legacy was not limited to research: McLaren inspired regulatory policies to ensure that assisted reproductive technologies were applied safely and ethically.
Anne McLaren remained active in research and advocacy for science until the last years of her life.
Unfortunately, she died in a tragic car accident on July 7, 2007, at the age of 80, along with her former husband, fellow scientist Donald Michie. Her legacy, however, lives on.
Her discoveries were fundamental to the creation of in vitro fertilization, helping millions of people realize their dream of having children.
Her commitment to scientific ethics and the advancement of women in science inspired generations of researchers.
Today, assisted reproduction laboratories and biomedical research centers around the world continue to benefit from the scientific foundations established by Anne McLaren.
Her name is immortalized in the history of science as one of the pioneers of reproductive genetics and one of the greatest scientists of her generation.

Annie Jump Cannon
Annie Jump Cannon was born on December 11, 1863, in Dover, Delaware, USA. From a young age, she was encouraged by her mother to explore astronomy, often observing the night sky through a small telescope.
She studied physics and astronomy at Wellesley College and graduated in 1884. Later, she pursued further studies at Radcliffe College and the Harvard College Observatory, where she gained access to leading astronomical facilities.
Cannon began working at the Harvard College Observatory as part of the group known as the "Harvard Computers," a team of women astronomers led by Edward Charles Pickering.
These women analyzed photographic plates and performed vital astronomical calculations. Annie Jump Cannon quickly stood out for her remarkable ability to classify stellar spectra with speed and precision.
She developed and refined the now-standard stellar classification system: OBAFGKM, based on a star’s temperature and spectral characteristics.
This system remains the foundation of stellar classification today. Cannon personally classified over 350,000 stars, an unmatched achievement.
Cannon lost her hearing due to an illness in her youth, which isolated her socially but did not hinder her scientific work.
She faced the gender discrimination typical of the era, as science was overwhelmingly male-dominated, yet she gained respect through her rigorous, groundbreaking research.
Annie Jump Cannon received many honors during and after her lifetime:
- In 1931, she became the first woman to receive the Henry Draper Medal from the U.S. National Academy of Sciences.
- She was the first woman to hold an official position in the International Astronomical Union.
- She received over a dozen honorary doctorates, including one from Oxford University, a rare achievement for a woman at the time.
- In 1938, she was appointed curator of Harvard’s photographic plate collection.
After her death in 1941, the American Astronomical Society established the Annie Jump Cannon Award, given annually to outstanding young female astronomers.
Annie Jump Cannon’s legacy is vast. Her classification system brought structure to the understanding of stars and continues to shape modern astrophysics. She also served as a trailblazer for women in science, proving that excellence knows no gender or barrier.

She developed and refined the now-standard stellar classification system: OBAFGKM, based on a star’s temperature and spectral characteristics.
This system remains the foundation of stellar classification today. Cannon personally classified over 350,000 stars, an unmatched achievement.
Cannon lost her hearing due to an illness in her youth, which isolated her socially but did not hinder her scientific work.
She faced the gender discrimination typical of the era, as science was overwhelmingly male-dominated, yet she gained respect through her rigorous, groundbreaking research.
Annie Jump Cannon received many honors during and after her lifetime:
- In 1931, she became the first woman to receive the Henry Draper Medal from the U.S. National Academy of Sciences.
- She was the first woman to hold an official position in the International Astronomical Union.
- She received over a dozen honorary doctorates, including one from Oxford University, a rare achievement for a woman at the time.
- In 1938, she was appointed curator of Harvard’s photographic plate collection.
After her death in 1941, the American Astronomical Society established the Annie Jump Cannon Award, given annually to outstanding young female astronomers.
Annie Jump Cannon’s legacy is vast. Her classification system brought structure to the understanding of stars and continues to shape modern astrophysics. She also served as a trailblazer for women in science, proving that excellence knows no gender or barrier.
Barbara Askins
Barbara Askins is a distinguished American scientist best known for her work in applied chemistry and photographic technology, particularly for developing image enhancement techniques.
Born in Alabama, her academic journey was unconventional, she returned to school after having children and later earned a degree and a master’s in chemistry from the University of Alabama. Defying social and gender barriers, she built a successful career in a field historically dominated by men.
In 1975, Barbara began working at NASA’s Marshall Space Flight Center, where she faced the challenge of recovering underexposed photographic images from space missions.
At the time, scientific images, such as X-rays, telescope photos, and geological records, often suffered from poor quality due to technical limitations.
To address this, she developed an innovative chemical process to enhance the density and clarity of photographic images, even after development.
Her technique involved post-processing photographs using radioactivity to excite the photographic emulsions. With this method, barely visible images could be rendered in high detail.
Askins' invention had far-reaching applications beyond space science, including medicine, archaeology, and industry, where it became possible to recover old X-rays, historical documents, and valuable scientific film footage.
In recognition of her groundbreaking invention, Barbara Askins was named “Inventor of the Year” in 1978 by the National Inventors Hall of Fame, the first woman ever to receive this award.
Her process was patented in the U.S., reflecting both its scientific importance and practical utility.
Askins became an inspirational figure for women in science and engineering, helping pave the way for greater female representation in technical fields.
Throughout her career, Barbara Askins proved that innovation arises from the intersection of applied science and real-world problems.

Barbara McClintock
Barbara McClintock was an American geneticist who made groundbreaking contributions to the field of biology, particularly genetics.
Born on June 16, 1902, in Hartford, Connecticut, McClintock spent most of her career studying corn (Zea mays) and discovered mobile genetic elements known as "jumping genes," which revolutionized the understanding of genetics.
Barbara McClintock developed a strong interest in science from an early age, encouraged by her family, although her mother was initially hesitant to support her studies.
She attended Cornell University, where she graduated in 1923 and later completed her doctorate in botany in 1927. At Cornell, McClintock worked on cytogenetics, the study of chromosomes, which became a fundamental foundation for her career.
During her undergraduate studies, McClintock became interested in corn genetics, which would become a central focus of her research.
She was one of the pioneers in using the microscope to map the location of genes on chromosomes, a remarkable technical and scientific feat for its time. In the 1940s and early 1950s, McClintock made her most significant discovery while studying corn. She realized that certain genes did not remain fixed in one position on the chromosome, but instead could "jump" from one position to another.
These mobile elements, which were later called transposons, could influence the expression of other genes and alter heritable plant traits in unpredictable ways.
Her discovery challenged the traditional view that genes were fixed, unchanging entities on chromosomes. These transposons explained, for example, the color variations in corn kernels.
McClintock proposed that mobile elements regulated the switching on and off of genes, a concept ahead of its time that was not understood or widely accepted by the scientific community for decades to come.
For many years, McClintock’s work was underappreciated, largely because her ideas on genetic transposition seemed too revolutionary for the classical genetics of the time.
However, with the advancement of molecular biology research in the 1970s, her discoveries began to be widely recognized.
Finally, in 1983, Barbara McClintock was awarded the Nobel Prize in Physiology or Medicine for her discovery of transposons.
She was the first woman to receive the Nobel Prize in this category without sharing it with other researchers, an important milestone both for science and for female representation.
Barbara McClintock is remembered as one of the most important scientists of the 20th century. Her work laid the foundation for many of the subsequent advances in molecular genetics, including the understanding of genetic mutations and gene regulation.
Her career is also seen as an example of perseverance, as she continued to work and develop her ideas even when faced with skepticism from the scientific community.
She died in 1992, leaving a legacy that continues to influence genetic research to this day.
Her discoveries changed the way we understand genome plasticity, opening doors to the study of the mechanisms that govern genetic variation and evolution.

Birgit Arrhenius
Birgit Arrhenius was born in 1932 in Sweden, into a family with a rich intellectual and scientific heritage, she was a descendant of Nobel Laureate Svante Arrhenius.
From an early age, she showed a deep interest in history, art, and the natural sciences, which led her to pursue a career that would eventually combine all three: archaeology.
She studied at Stockholm University, where she would later become a central figure in the development of scientific and analytical archaeology in Sweden and throughout Europe.
Throughout her career, Arrhenius became renowned for integrating laboratory-based scientific techniques, such as spectrometry, metal analysis, isotopic research, and soil studies, into archaeological investigation.
This interdisciplinary approach allowed for much more accurate reconstructions of historical contexts than traditional methods.
She specialized in archaeometry and the analysis of artifacts from the Iron Age, including extensive studies of Germanic and Viking cultures.
She led major excavations across Scandinavia and was among the first to promote collaboration between archaeologists and natural scientists.
Arrhenius, following in her father's footsteps, became a professor at Stockholm University. Between 1986 and 1998, she held the position of Professor of Laboratory Archaeology and was also the first director of the university's Archaeological Research Laboratory, founded in 1976.
Throughout her career, she played a prominent role in important excavations and in the scientific dissemination of archaeological finds, especially at the historic sites of Helgö and Björkö, two of the most extraordinary Viking-era sites in Sweden.
In an article published in 1983, Arrhenius proposed a reassessment of the chronology of the Vendel burial mounds, contributing to a new understanding of the culture and funerary rituals of that society.
In 1992, using laser scanning technology, a groundbreaking technique for archaeology at the time, a remarkable detail was revealed on one of the Torslunda plaques: the figure of a dancing warrior, present in bronze molds used to decorate helmets, with one of his eyes abruptly torn out.
This discovery was interpreted as a possible ritual reference to the Germanic god Odin, traditionally depicted with a single eye.
Her efforts helped establish environmental archaeology and the scientific analysis of organic remains as essential tools in archaeological research. Furthermore, Birgit played a crucial role in founding and developing the archaeometry lab at Stockholm University, where she trained and mentored future generations of archaeologists.
Birgit Arrhenius was a member of the Royal Swedish Academy of Sciences and received numerous academic honors during her lifetime.
Her pioneering work earned her awards and recognition both nationally and internationally, particularly for her contributions to the professionalization and scientific advancement of archaeology. She also held leadership roles in various research institutions and cultural heritage committees.

Cecilia Payne-Gaposchkin
Cecilia Payne-Gaposchkin was a British astrophysicist who made one of the most important discoveries in the history of astronomy: that stars are composed primarily of hydrogen and helium.
Her research revolutionized our understanding of stellar composition and the formation of the universe, and is considered one of the greatest contributions to astrophysics.
Cecilia Payne was born on May 10, 1900, in Wendover, England. From an early age, she demonstrated a deep interest in science and mathematics, but faced significant obstacles due to gender bias, which limited opportunities for women in science.
She studied at Newnham College at the University of Cambridge, where she fell in love with astronomy. Although she completed her studies at Cambridge, the university still did not grant degrees to women, which led her to seek opportunities in the United States.
In 1923, Cecilia Payne moved to the United States to study at the Harvard College Observatory. She became the first person to earn a PhD in astronomy from Radcliffe College (affiliated with Harvard) in 1925.
Her doctoral thesis, “Stellar Atmospheres,” was a true scientific breakthrough. Using Meghnad Saha’s ionization theory, she demonstrated that stars are composed primarily of hydrogen and helium, rather than heavier elements as previously believed.
At the time, this idea was initially rejected by established scientists, such as Henry Norris Russell, who later recognized the importance of Payne’s discovery.
Despite her transformative discovery, Payne faced many challenges throughout her career due to bias against women in science.
For many years, she was not recognized fairly and, despite her PhD, worked in low-paid assistant positions. Nevertheless, she persisted in her research, focusing on stellar spectroscopy and stellar evolution.
She continued to produce important work in several areas of astrophysics and supervised the work of many students who went on to become renowned astrophysicists. In 1956, Payne was finally granted a full professorship at Harvard, becoming the first woman to hold that position at the university.
She was also later named chair of the Department of Astronomy, cementing her role as a pioneer for women in academia.
Cecilia Payne-Gaposchkin passed away on December 7, 1979, leaving a lasting legacy in astronomy. Her scientific contributions laid the foundation for modern knowledge about the composition and evolution of stars. She was also a passionate advocate for the education of women in the sciences and helped pave the way for future generations.
Her work is considered one of the greatest scientific achievements of the 20th century, and her story is often cited as an example of the struggle and perseverance of women in science.
