September 9,1945: First Computer Bug Revealed


1945 – Grace Hopper is forever immortalized in the computer world as the first person to find a bug in a computer system. Litterally. The bug was a moth in between Relay #70 on Panel “F” of the Harvard Mark II Aiken Relay Calculator.From there on end, “Bug” meant a problem in a computer system. I guess once the moth was removed, the word “Debug” was also added.BTW – The relay functioned properly after the moth was removed.

1947 – It sounds like that same relay finally failed 2 years later.
