She continued working at Harvard after the war, focusing on applied physics and engineering sciences. She went on to work for private companies and helped create and popularize COBOL (common business-oriented language), the first standardized computer language for general business.

President George H.W. Bush awarded Hopper the National Medal of Technology in 1991, making her the first woman to receive this honor as an individual.

In recognition of her importance to the computer science field, she posthumously received the Presidential Medal of Freedom in 2016.

Katherine Johnson

As a Black woman in STEM in the 1930s, Katherine Johnson broke gender and race barriers to become one of the most influential women in computer science. She demonstrated a talent for math from a young age and graduated from West Virginia State College with degrees in mathematics and French in 1937.

In 1953, Johnson got a job at the National Advisory Committee on Aeronautics, the precursor to the National Aeronautics and Space Agency (NASA). She was assigned first to work on an all-woman team analyzing flight data.

In 1962, she performed the calculations for John Glenn's Friendship 7 orbital flight. She also did some calculations for the Apollo 11 and Apollo 13 missions and continued working at NASA until 1986.

Johnson is one of the women profiled in the book, "Hidden Figures," which was later adapted into an Oscar-nominated film. In recognition of her importance to STEM, Johnson received numerous awards, including the National Medal of Freedom in 2016.

Sister Mary Kenneth Keller

Born in 1913 in Ohio, Sister Mary Kenneth Keller joined the Sisters of Charity of the Blessed Virgin Mary in 1932. Keller became the first woman in the United States to earn a Ph.D. in computer science in 1965, after previously earning degrees in math and physics from DePaul University.

She also completed graduate work at other universities, including at Dartmouth College's computer lab, which typically excluded women at that time. While at Dartmouth, Keller helped develop the BASIC programming language, which made coding more accessible to people in fields beyond math and science.

After graduating with her Ph.D. from the University of Wisconsin Madison, she founded the department of computer science at Clark University in Iowa and remained there for about 18 years. Keller worked to attract more women to the computer science field and invited students to bring their children to class.

Joy Buolamwini

Born in 1989, Joy Buolamwini is a Black computer scientist and researcher at MIT. She is the founder of the Algorithmic Justice League, which focuses on making tech more equitable and accountable. She is also on the Global Tech Panel, advising governments around the world on using AI technology appropriately.

She holds a master's degree and Ph.D. in media arts and sciences from MIT. Her groundbreaking graduate thesis discusses gender and racial basis in artificial intelligence technology at companies like Amazon, Microsoft, and IBM. She describes herself as a "poet of code" and writes about AI in the popular press.

She has received recognition for her role as one of the most influential women in computer science, including being named as one of Forbes' 30 Under 30, MIT Tech Review's 35 under 35, and Fortune's World's 50 Great Leaders. More than 1.4 million people viewed her 2017 TED talk on algorithmic bias.
