Computer Bug



In 1945, Grace Murray Hopper was working on the Harvard University Mark II Aiken Relay Calculator. On the 9th of September, 1945, when the machine was experiencing problems, an investigation showed that there was a moth trapped between the points of Relay #70, in Panel F. The operators removed the moth and affixed it to the log. (See the picture above.) The entry reads: "First actual case of bug being found."
