Who was Grace Hopper?

All of this is impressive enough, but Grace Hopper’s work on projects like Mark I and II, and most especially UNIVAC I, one of the first commercial computers, was more than just impressive. It was groundbreaking.
Grace Hopper’s biography is undoubtedly impressive. Born in New York City in 1906, she studied mathematics and physics at Yale, earned her doctorate, and then taught mathematics herself at the elite Vassar College. In 1944, she joined the U.S. Navy to do her part in World War II. At the end of her military career in 1986, she was a Rear Admiral. For several years, she worked at the Harvard Computer Laboratory and for an influential computer company. She even returned from retirement to active duty when the Navy asked her to help with computer problems.
