Grace Hopper invented the first compiler for a computer language, which is a program that transforms a set of coded instructions into a machine-readable language. Hopper was also one of the pioneering computer programmers who developed the Computer Business Oriented Language, popularly known as "COBOL."
Hopper, born Grace Brewster Murray, was a United States Navy rear admiral, mathematician and a prominent figure in the history of computer programming. Aside from inventing a compiler, she also provided the design for UNIVAC I, considered as the world's first commercial electronic computer. Due to her significant contributions in the field of computers, she was fondly called by her colleagues the "Grand Lady of Software," "Grandma COBOL" and "Amazing Grace."
