1952- Grace Murray Hopper
COMPUTER-LANGUAGE CREATOR
One of the first women in the Navy to attain the rank of rear admiral, Hopper was a math whiz and a founding mother of computer languages; her focus was on making them more accessible to programmers. Your swift, snazzy software exists because of her. She coined the term "debugging" (1947) after removing an actual moth from the circuitry of a malfunctioning Havard Mark II computer.
