I saw this a while ago on Wikipedia and included it in our company journal. I was amazed at how many people had not heard the story. I am posting it here now in recognition of a similar article on "help i found a bug in mycode" where he draws comparison to a more modern day version.
The similarity is strange, because only recently I had been recounting to colleagues an experience with my son (10 years old). A storm fly, one of those tiny little things about 1mm by 2mm had some how crept into my LCD screen on my monitor and to all appearances, was crawling all over my document. I called my son over remarking, “Come take a look at this bug in my screen”. His response was naïve but endearing as he responded, “Wow, Dad is that a virus?” much to my delight.
The picture above relates to the following text. “While Grace Hopper was working on the Harvard Mark II Computer at Harvard University, her associates discovered a moth stuck in a relay and thereby impeding operation, whereupon she remarked that they were "debugging" the system. Though the term computer bug cannot be definitively attributed to Admiral Hopper, she did bring the term into popularity. The remains of the moth can be found in the group's log book at the Smithsonian Institution's National Museum of American History in Washington, D.C.”
