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.
