The term ''bug'', in the sense of defect, dates back at least to 1878 when [[Thomas Edison]] wrote "little faults and difficulties" in his inventions as "Bugs".

A popular story from the 1940s is from [[Admiral Grace Hopper]].<ref>{{Cite web |url=https://books.google.com/books?id=JT0EAAAAMBAJ&pg=RA1-PA33 |title=InfoWorld Oct 5, 1981 |date=5 October 1981 |access-date=July 17, 2019 |archive-date=September 18, 2019 |archive-url=https://web.archive.org/web/20190918012636/https://books.google.com/books?id=JT0EAAAAMBAJ&pg=RA1-PA33&lpg=RA1-PA33&focus=viewport |url-status=live }}</ref>. While she was working on a [[Harvard Mark II|Mark II]] computer at Harvard University, her associates discovered a [[moth]] stuck in a relay that impeded operation and wrote in a log book "First actual case of a bug being found". Although probably a [[word play|joke]], conflating the two meanings of bug (biological and defect), the story indicates that the term was used in the computer field at that time.

Similarly, the term ''debugging'' was used in aeronautics before entering the world of computers. A letter from [[J. Robert Oppenheimer]], director of the [[WWII]] atomic bomb [[Manhattan Project]] at Los Alamos, used the term in a letter to Dr. [[Ernest Lawrence]] at UC Berkeley, dated October 27, 1944,<ref>{{Cite web |url=https://bancroft.berkeley.edu/Exhibits/physics/images/bigscience25.jpg |title=Archived copy |access-date=2019-12-17 |archive-date=2019-11-21 |archive-url=https://web.archive.org/web/20191121001830/https://bancroft.berkeley.edu/Exhibits/physics/images/bigscience25.jpg |url-status=live }}</ref> regarding the recruitment of additional technical staff.
