12 May - Konrad Zuse presented the Z3 world's first working fully automatic computer

 

On 12 May 1941, Konrad Zuse presented the Z3, the world's first working programmable, fully automatic computer, in Berlin.

Konrad Zuse's Z3 is considered by many to be the world's first programmable digital computer. It was a significant milestone in the history of computing, demonstrating the feasibility of automatic computation using binary logic and electromechanical components. The Z3 was primarily designed to perform complex calculations for engineering and scientific purposes. Zuse's work laid the groundwork for the development of modern computers.
