Thomas (Tommy) Harold Flowers, MBE (22 December 1905 - 28 October 1998) was a British engineer. During World War II, Flowers designed "Colossus", an early electronic computer, to help solve encrypted German messages. Flowers was born in London's East End on 22 December 1905, the son of a bricklayer. After an apprenticeship in mechanical engineering, he earned a degree in electrical engineering at the University of London. Wikipedia
