Moth in relay is a bug. Maybe the earliest bug discovered?

Ah geek... I had seen this one before. This is the first incidence of a "bug" where an actual physical bug got stuck in the machine.

first computer bug

bug in code came from moth in relay...? during the punch card days the computational machine must have had relays in it (on-off mechanism)

The First "Computer Bug":
Moth found trapped between points at Relay # 70, Panel F, of the Mark II Aiken Relay Calculator while it was being tested at Harvard University, 9 September 1945. The operators affixed the moth to the computer log, with the entry: "First actual case of bug being found". They put out the word that they had "debugged" the machine, thus introducing the term "debugging a computer program". In 1988, the log, with the moth still taped by the entry, was in the Naval Surface Warfare Center Computer Museum at Dahlgren, Virginia.
