Turing has definitely increased in visibility over the last few decades. Von Neumann was considered the "father of digital computing", because he set down in detail how a general purpose stored-program digital computer ought to work. One was built, and it worked. A few billion Von Neumann architecture machines later...

Turing's automata theory work was obscure and not very usable. Turing's code breaking work was very specialized. The real theoretician of cryptanalysis was Friedman, who gave the field a theoretical basis, along with breaking the Japanese Purple cypher and founding the National Security Agency.

"Colossus", the electronic codebreaking machine at Bletchley, was not a general purpose computer. It was a key-tester, like a Bitcoin miner. Its predecessors, the electromechanical "bombes", were also key-testers.

Almost forgotten today are Eckert and Mauchly. They were the architects of the ENIAC, which was a semi general purpose computer programmed with plugboards and knobs. This was a rush job during WWII, when naval gunnery and navigation tables were needed in a hurry. It did the job it was supposed to do. After the war, they formed Eckert-Mauchley Computer Corporation, and produced the BINAC.[1] This was the minimum viable product for a commercial electronic digital computer. All the essential subsystems were there - CPU, memory, magnetic tape drive, printer. Everything was duplicated for checking purposes. That got them acquired by Remington Rand, and their next machine was the famous UNIVAC I, with more memory, better tape drives, a full set of peripherals, and profitable sales. Eckert had a long career with Remington Rand/UNIVAC/Unisys. Mauchley stayed for a few years and then did another startup. More like a good Silicon Valley career.
