Google Doodle celebrating the birthday of computer scientist Grace Hopper (1906-1992).
Grace was teaching math at Vassar College when she joined the Naval Reserves in 1943 at age 37. When she finally retired fully in 1986, she was the oldest member of the US armed forces. During her long career, Grace led the team that created the programming language COBOL. COBOL allows computers to communicate using language in addition to numbers. Grace also coined the phrase “debug” for fixing computer glitches after a moth flew into her machine and upset the system. She is buried at Arlington National Cemetery.
