Manchester: birth of the first working computer
Two University of Manchester scientists, Freddie Williams and Tom Kilburn, are credited with running the world's first stored program computer.
I grew up thinking that one of ENIAC/EDSAC/EDVAC was the first stored-program computer. It turns out that ENIAC came close to being one, but didn't. There's more info at Wikipedia. According to Wikipedia, the Manchester "Baby" was developed in 1948, which was more than 50 years ago :)
