Konrad Zuse

Verified Timeline

Lore & Background

The Z1 was a floating-point binary mechanical calculator with limited programmability, but it never worked well due to insufficient mechanical precision. In 1939, Zuse was called to military service, where he was given resources to build the Z2, a revised version using telephone relays. In 1941, he completed the Z3, a binary 22-bit floating-point calculator with programmability and loops, but it lacked conditional branching in its original design and was not Turing-complete. During World War II, he also built the S1 and S2 computing machines for the German military, the S2 being the first process control computer.

Reader's Guide

Konrad Zuse's significance lies in his independent creation of the first programmable computer, the Z3, which became operational in May 1941. His early patents from 1937 anticipated the von Neumann architecture. Despite intellectual isolation from 1936 to 1945, Zuse's innovations laid foundational groundwork for modern computing. His company, Zuse KG, produced a series of computers, including the Z11 and Z22, the latter being the first with magnetic storage memory. His legacy is that of a self-taught inventor whose machines, though initially funded by the Nazi regime, ultimately contributed to the global development of digital computers.
