Women have been programming since before it was a thing. Take Ada Lovelace: Daughter of Lord Byron, she's often credited as the first computer programmer. Her work on Charles Babbage's Analytical Engine contains notes of the first machine-implemented algorithm.

Hungarian-born Rózsa Péter studied number theory and poetry before becoming interested in the idea that would become recursion theory. She published her paper "Recursive Functions" in 1951, but it wasn't until the mid-50's that she began to apply her work to the realm of computers.

In her career with the Navy, Rear Admiral Grace Hopper worked on the first commercial computer (UNIVAC) and laid the groundwork for the programming language COBOL. But her most notable invention was the compiler, which can transform a source language into binary code. (In other words, it can translate the code you and I write into 0s and 1s.) She developed it in 1952, but she said "Nobody would touch it. They told me computers could only do arithmetic."

One of the first African-American women to earn a Ph.D in mathematics, Evelyn Boyd Granville focused on aeronautics and space during her career. In 1956, she worked with NASA and IBM on Project Mercury, the first manned space flight. She worked with NASA again a few years later on the Apollo Project.Videos from Vimeo are also easy to embed.

One of the first women (if not the first woman) to earn a Ph.D in computer science, Sister Mary Kenneth Keller also contributed to the development of the BASIC language during her time at Dartmouth College. She then founded the computer science department at Clarke College and directed it for the next 20 years.

A professor at Cambridge Computer Laboratory, Spärck Jones was interested in natural language processing and information retrieval. In 1972, she introduced the concept of inverse document frequency, which most search engines still rely on.

Often called "the Mother of the Internet," Radia Perlman's work on spanning tree protocol enabled the development of modern networking. She holds more than 100 patents, which is what mothers do best.
