Grace Hopper
Grace Brewster Murray Hopper (December 9, 1906 – January 1, 1992), née Grace Brewster Murray, was an American computer scientist and United States Navy Rear Admiral. She was one of the first programmers of the Harvard Mark I computer in 1944, invented the first compiler for a computer programming language, and was one of those who popularized the idea of machine-independent programming languages which led to the development of COBOL, one of the first high-level programming languages. She is credited with popularizing the term "debugging" for fixing computer glitches (in one instance, removing a moth from a computer).
Owing to her accomplishments and her naval rank, she is sometimes referred to as "Amazing Grace". The U.S. Navy Arleigh Burke class guided-missile destroyer USS Hopper (DDG-70) is named for her, as is the Cray XE6 "Hopper" supercomputer at NERSC.
Early life and education
Hopper was born in New York City. She was the oldest in a family of three children. Her parents, Walter Fletcher Murray and Mary Campbell Van Horne, were of Dutch and Scottish descent, and attended West End Collegiate Church. Her great-grandfather, Alexander Wilson Russell, an admiral in the US Navy, fought in the Battle of Mobile Bay during the Civil War.
