Grace Hopper’s Bug Discovery
1945 On Sept. 9, the Mark II computer system at the Computation Laboratory at Harvard University was on the fritz. The colossal calculator, which famously took up hundreds of cubic feet in the lab, was plagued by a mysterious glitch. When the team members, led by Grace Murray Hopper, a budding computer scientist from the U.S. Naval Reserve, open the computer for a closer look, they discover the first true computer bug.
Lodged between points in relay #70 in panel F was a 2-inch moth that had flown into the machine and caused the ruckus. While the term computer bug was part of computer users’ vocabulary before 1945, Hopper and her team are credited with the discovery of the world’s first computer bug and coin the phrase “debugging a computer program.” This legend even helped one young man become a millionaire. In March 2000, 25-year-old Joe Trela correctly answers “moth” to the final question (was it a moth, roach, fly or Japanese beetle that shorted out an early supercomputer?) on ABC’s Who Wants to Be a Millionaire to claim the $1 million grand prize.
