They broke the sound barrier — and gender barriers along the way.
And inspiring more young women to pursue careers in science starts with simply sharing their stories.
Let’s write their stories permanently into history.
Listen to the Stories
Ana Roqué de Duprey
Ana Roqué de Duprey was born in Puerto Rico in 1853. She started a school in her home at age 13 and wrote a geography textbook for her students, which was later adopted by the Department of Education of Puerto Rico. Roqué had a passion for astronomy and education, founding several girls-only schools as well as the College of Mayagüez, which later became the Mayagüez Campus of the University of Puerto Rico. Roqué wrote the Botany of the Antilles, the most comprehensive study of flora in the Caribbean at the beginning of the 20th century, and was also instrumental in the fight for the Puerto Rican woman’s right to vote.

Ruth Rogan Benerito
Ruth Rogan Benerito was an American chemist and pioneer in bioproducts. Benerito is credited with saving the cotton industry in post-WWII America through her discovery of a process to produce wrinkle-free, stain-free, and flame-resistant cotton fabrics. In addition to this work, Benerito also developed a method to harvest fats from seeds for use in intravenous feeding of medical patients. This system became the foundation for the system we use today. After retiring from the USDA and teaching university courses for an additional eleven years, Benerito received the Lemelson-MIT Lifetime Achievement Award both for her contributions to the textile industry and her commitment to education.

Edith Clarke
Edith Clarke was a pioneering electrical engineer at the turn of the 20th century. She worked as a “computer,” someone who performed difficult mathematical calculations before modern-day computers and calculators were invented. Clarke struggled to find work as a female engineer instead of the ‘usual’ jobs allowed for women of her time, but became the first professionally employed female electrical engineer in the United States in 1922. She paved the way for women in STEM and engineering and was inducted into the National Inventors Hall of Fame in 2015.

Mollie Orshansky
Mollie Orshansky was a food economist and statistician whose work on poverty thresholds pioneered the way the U.S. Government defines poverty. By using the cost of the cheapest nutritionally adequate diet to calculate a cost of living expense for families of various sizes, Orshansky developed guidelines which eventually became the federal government’s official statistical definition of poverty. Her work provided a way to assess the impact of new policies on poor populations, which to this day remains a standard measure of new policies, demonstrating the enduring impact of her work on American public policy.

Mary Engle Pennington
Mary Engle Pennington was an American chemist at the turn of the 20th century. At a time when few women attended college, Pennington completed her PhD and went on to work as a bacteriological chemist at the U.S. Department of Agriculture. Shortly after arriving at the USDA, Pennington became chief of the newly established Food Research Laboratory. During her 40-year career at the USDA, Pennington’s pioneering research on sanitary methods of processing, storing, and shipping food led to achievements such as the first standards for milk safety as well as universally accepted standards for the refrigeration of food products.

Ellen Ochoa
In 1993, Dr. Ellen Ochoa became the first Hispanic woman to go to space when she served on a nine-day mission aboard the space shuttle Discovery. She has flown in space four times, logging nearly 1,000 hours in orbit. Prior to her astronaut career, she was a research engineer and inventor, with three patents for optical systems. Ochoa is also the first Hispanic (and second female) to be named director of NASA’s Johnson Space Center.

Calutron Girls
Isolating enriched uranium was one of the most difficult aspects of the Manhattan Project, which produced the first nuclear bombs during World War II. Wartime labor shortages led the Tennessee Eastman Company to recruit young women, who were mostly recent high school graduates, to operate the calutrons that used electromagnetic separation to isolate uranium. Despite being kept in the dark on the specifics of the project, the “Calutron Girls” proved to be highly adept at operating the instruments and optimizing uranium production, achieving better rates for production than the male scientists they worked with.

Virginia Holsinger
Virginia H. Holsinger was an American chemist known for her research on dairy products and food security issues. Holsinger developed a nutritious and shelf-stable whey and soy drink mixture that is distributed internationally by food donation programs as a substitute for milk. She also created a grain blend that can be mixed with water to provide food for victims of famine, drought, and war. Additionally, her work on the lactase enzyme formed the basis for commercial products to make milk digestible by lactose-intolerant people. Through these discoveries, Holsinger’s work has had a major impact on worldwide public health.

Grace Hopper
Rear Admiral Grace Murray Hopper was at the forefront of computer and programming language development from the 1930s through the 1980s. One of the crowning achievements of her 44-year career was the development of computer languages written in English, rather than mathematical notation — most notably, the common business computing language known as COBOL, which is still in use today. Hopper's legacy is still honored by the annual Grace Hopper Celebration of Women in Computing Conference.

Lydia Villa-Komaroff
Lydia Villa-Komaroff is considered to be a trailblazer in the field of molecular biology. She faced many adversities she faced throughout her lifetime — at one point, an advisor told her that women did not belong in chemistry, fortuitously inspiring her to switch her major to biology — but she pursued her passion in spite of opposition. In 1978, Villa-Komaroff made waves with a published paper detailing her most notable discovery — that bacteria could be engineered to produce human insulin. She currently serves as the Chief Scientific Officer (CSO) at Cytonome/ST.

Ada Lovelace
Ada Lovelace is considered to be the founder of scientific computing and the first computer programmer. Her algorithm — which history has come to know as the first one designed for a machine to carry out — was intended to be used for Charles Babbage’s Analytical Engine, which Lovelace would sadly not see built during her lifetime. Lovelace passed away in 1852, but her previously little-known work and "poetical" approach to science has broken through to inspire present-day young women interested in computer programming.

The Mercury 13
The Mercury 13, also sometimes known as the “Members of the First Lady Astronaut Trainees” (FLATs), were a group of women who participated in training to become astronauts for the country's first human spaceflight program in the early 1960s. FLATs was never an official NASA program, and was unfortunately eventually discontinued, but the commitment and determination of these women to get into space has been credited with paving the way for such astronauts as Mae Jemison, the first African-American woman in space.

The ENIAC Programmers
As part of a secret World War Two project, six young women programmed the first all-electronic programmable computer. When the project was eventually introduced to the public in 1946, the women were never introduced or credited for their hard work -- both because computer science was not well understood as an emerging field, and because the public's focus was on the machine itself. Since then, the ENIAC Programmers Project has worked hard to preserve and tell the stories of these six women.

Rosalind Franklin
Rosalind Franklin was a British chemist and crystallographer, best known for her research that was essential to elucidating the structure of DNA. During her lifetime, Franklin was not credited for her key role, but years later she is recognized as providing a pivotal piece of the DNA story. Franklin spent the last five years of her life studying the structure of plant viruses and passed away in 1958.
