Grace Hopper (1906-1992), sometimes referred to as ‘Amazing Grace’, was a computer scientist and an Admiral in the US Navy. In 1944, she invented the first compiler for a computer programming language.

She earned her master’s and PhD in mathematics from Yale, and began teaching at Vassar in 1931. She was part of the US Navy Reserve during World War II, all while working for the Harvard Computation Lab, where she was part of the Mark I computer programming project. She remained on active duty well beyond the retirement age, becoming the oldest active-duty officer in the history of the Navy, at 79 years of age.
