Grace Brewster Hopper (December 9, 1906 to January 1, 1992) was an American computer scientist, mathematician, and United States Navy rear admiral. A pioneer of computer programming, Hopper was the first to devise the theory of machine-independent programming languages and used this theory to develop the FLOW-MATIC programming language and COBOL, an early high-level programming language still in use today. She was also one of the first programmers on the Harvard Mark I computer. She is credited with writing the first computer manual, "A Manual of Operation for the Automatic Sequence Controlled Calculator." The following audio recording is from a 1982 presentation.
