Konrad Zuse

Konrad Zuse (1910-1995) was an under-credited but highly fruitful German computer designer. Working in relative isolation in pre-war Germany, Zuse built three prototype electronic computers (V1, V2 and V3) which computed using the binary number system and other advanced design concepts. His third model, the Z3, was completed well before any of the computers shown below. However, Zuse was in a chaotic German wartime environment and lacked official support, and all three of the working models were destroyed during World War II. Despite being drafted into the German army, Zuse survived the war, built another computer in Switzerland (the V4), and later was the first designer to propose pipelining the computations of a computer processor. In 1949, Zuse formed Zuse KG, where he worked until 1966. Zuse KG grew into a leading manufacturer of small scientific computers, employing a thousand people.
