Ask The Experts | Detailing Colossus

The National Museum of Computing houses the world’s largest collection of working historical computers.

Among our collection is a rebuild of Colossus - a working example of the 10 cryptography code-breaking machines that cracked the secret communications of Hitler during World War II.

The 10 Colossus either disappeared into the security state or failed to survive the war; many of the technical materials were deliberately destroyed.

Gavin Clarke talks to National Museum volunteer guide Peter Hoath about the significance of one particular technical diagram; a diagram drawn years later from the memory of Tommy Flowers - the individual responsible for Colossus.
