Summary
The article recounts how Colossus, the first large-scale programmable electronic digital computer, was built at Bletchley Park to decrypt the Lorenz cipher ('Tunny') during WWII. It highlights key figures—Flowers, Turing, Tutte, Tiltman—and the machine's leap from relays to tubes, its scientific methods like Turingery, and its lasting impact on computing and cryptography. It also notes the IEEE Milestone dedication and the secrecy surrounding Colossus after the war.
