Grace Hopper was an American computer scientist and United States Navy rear admiral. In 1949, Hopper joined the team developing the UNIVAC I, which was the first known large-scale electronic computer. She believed that a programming language based on English was possible and that it would be much easier to work with a computer by giving commands in English, which the computer then would translate to machine code by itself. Her idea was very quickly denied and wasn’t accepted for three years. In 1952, her programming team developed the first computer language compiler called A-0, which translated mathematical code into machine-readable binary code. Still, Hopper didn’t forget her initial idea that it could be done with language too. So her team continued the work and developed Flow-Matic, the first programming language to use English-like commands. In 1959, she participated in the development of one of the first modern programming languages—COBOL.
