Colossus is thus regarded [2] as the world's first programmable, electronic, digital computer, although it was programmed by switches and plugs and not by a stored program. [ 3 ] Colossus was designed by General Post Office (GPO) research telephone engineer Tommy Flowers [ 1 ] based on plans developed by mathematician Max Newman at the ...
ENIAC (/ ˈ ɛ n i æ k /; Electronic Numerical Integrator and Computer) [1] [2] was the first programmable, electronic, general-purpose digital computer, completed in 1945. [ 3 ] [ 4 ] Other computers had some of these features, but ENIAC was the first to have them all.
Due to World War II, Zuse's work went largely unnoticed in the United Kingdom and United States. Possibly his first documented influence on a US company was IBM's option on his patents in 1946. [19] The Z4 also served as the inspiration for the construction of the ERMETH, the first Swiss computer and one of the first in Europe. [20]
The Z3 was a German electromechanical computer designed by Konrad Zuse in 1938, and completed in 1941. It was the world's first working programmable, fully automatic digital computer. [3] The Z3 was built with 2,600 relays, implementing a 22-bit word length that operated at a clock frequency of about 5–10 Hz. [1] Program code was stored on ...
This computer was destroyed in the bombardment of Berlin in December 1943, during World War II, together with all construction plans. The Z1 was the first in a series of computers that Zuse designed. Its original name was "V1" for Versuchsmodell 1 (meaning Experimental Model 1).
Thomas Harold Flowers MBE (22 December 1905 – 28 October 1998) was an English engineer with the British General Post Office. During World War II, Flowers designed and built Colossus, the world's first programmable electronic computer, to help decipher encrypted German messages.

The Z4 was arguably the world's first commercial digital computer, and is the oldest surviving programmable computer. [1]: 1028 It was designed, and manufactured by early computer scientist Konrad Zuse's company Zuse Apparatebau, for an order placed by Henschel & Son, in 1942; though only partially assembled in Berlin, then completed in Göttingen in the Third Reich in April 1945, [2] but not ...
