Discovered First Computer Bug
Grace Hopper
Born December 9, 1906 d. 1992
American computer pioneer, U.S. Navy Rear Admiral. While she was working on a Mark II Computer in 1947, her team discovered a moth stuck in a relay causing the computer to malfunction, causing the first "computer bug." Though the term "bug" had been used in engineering since the 1800s, this is the first recorded instance of a literal "computer bug." The moth can be seen in their log book at the Smithsonian Institution's National Museum of American History.
