On this date in 1947, the operators of the Mark II Aiken Relay Calculator removed a moth that was blocking a relay. While the term “bug” had been in use in engineering circles for quite a while before then, this was the first known incident of an actual bug causing a computer to malfunction. The operators preserved the bug in their log, which you can see in the photo below.
