We lost a co-inventor of ENIAC, John Mauchly, on this day in 1980. ENIAC is claimed to be the "first general purpose electronic digital computer", but I guess it comes down to a matter of definition[*], as every culture likes to be the "first" (just ask the Penguins, for example); for "computer" you could go all the way back to the Mk-I Antikythera (Hellenic variation, from about the 100BC production run)...
