Birth of the Baby

On June 21st, 1948, at Manchester University, shortly after 11 o'clock in the morning, the world's first stored-program electronic digital computer successfully executed its first program. That program was written by Tom Kilburn who, along with Freddie Williams designed and built the machine. It was called the Small-Scale Experimental Machine, but was soon nicknamed "The Baby".
