The First Computer Bug Was an Insect - Apparently.
In 1947, a team of engineers working on the Harvard Mark II computer discovered a moth stuck in one of the relay switches, causing the machine to malfunction. The engineers taped the moth to the computer log with the note "First actual case of bug being found," thus coining the term "computer bug." This incident was documented by Grace Hopper, a pioneering computer scientist, and is still referenced today as the origin of the term "bug" in computing.
