Dr. Joy Buolamwini is a computer scientist and poet of code who uses art and research to illuminate the social implications of artificial intelligence. She founded the Algorithmic Justice League to create a world with more equitable and accountable technology.

Grace Hopper was one of the first people to work with modern digital computers and developed the first compiler for a computer programming language. She had the idea that programs could be written in a language that was close to English rather than in machine code.

Radia Joy Perlman is an American computer programmer and network engineer. She is a major figure in assembling the networks and technology to enable what we now know as the internet.

Born two centuries ago, Ada Lovelace was a pioneer of computing science. She took part in writing the first published program and was a computing visionary, recognizing for the first time that computers could do much more than just calculations. The second Tuesday in October has become Ada Lovelace Day, on which the contributions of women to science, technology, engineering, and mathematics are honored.

Margaret Hamilton was responsible for the software that allowed astronauts Neil Armstrong and Buzz Aldrin to land on the Moon. She is also credited with inventing the term software engineering. The Apollo 11 moon landing nearly ended in failure -- until Margaret Hamilton's flight software saved the day.

Cynthia Breazeal was the associate director of MIT Media Lab and founder and director of the Personal Robots Group. In 2002 she co-created a robot named Leonardo. Leonardo acknowledges faces, changes expressions, and reacts to touch. Breazeal also supervised the development of robots made for specific purposes.

Marie Curie was a Polish and naturalized-French physicist and chemist who conducted pioneering research on radioactivity. She was the first woman to win a Nobel Prize, the first person to win a Nobel Prize twice, and the only person to win a Nobel Prize in two scientific fields. Marie Curie is remembered for her discovery of radium and polonium, and her huge contribution to finding treatments for cancer.

Chien-Shiung Wu was a Chinese American experimental physicist who made significant contributions in the research of radioactivity. She was known as the "First Lady of Physics." Dr. Chien-Shiung Wu’s pioneering work is regarded as a standard among physicists today. Her later research focused on the causes of sickle-cell anemia. Wu retired in 1981 and devoted her time to educational programs in China, Taiwan, and the United States.

Kamala Sohonie was the first Indian woman to receive a PhD in a scientific discipline; in her case biochemistry. Her acceptance into and work at the Indian Institute of Science, Bangalore, paved the way for women to be accepted into the institution for the first time in its history.
