The First Computer Bug Was an Insect - Apparently.
In 1947, a team of engineers at Harvard University was working on the Mark II computer when they encountered a problem that would become the first recorded computer bug. The team was trying to debug the system, but it wasn't until they found a moth stuck in one of the relays that they realized the cause of the malfunction. The moth was taped into the computer's log with the note "First actual case of bug being found" – a term that would stick as a metaphor for errors in programming.
