Annie Easley

Annie Easley was a computer scientist, rocket scientist, and mathematician based in America. She worked for the Lewis Research Center, which is now Glenn Research Center of the National Aeronautics and Space Administration. She also worked for NASA’s predecessor-the National Advisory Committee for Aeronautics as a leading member. During her leadership at NACA, the Centaur rocket stage-the first Africans-Americans software to work at NASA was developed.

Grace Hopper

She was a brilliant mathematician and computer scientist who joined the United States Navy and became a rear admiral. She pioneered computer technology and was an accomplished computer programmer.

Ada Lovelace

Ada Lovelace is the world’s first computer programmer. She was the first person to write a program - a series of commands that Charles Babbage’s mechanical computer could use to do complicated calculations. Ada believed machines could do more than just math and correctly predicted many of their future uses, such as creating graphics and music.
