First Computer

The Z1 was the first mechanical computer created by a construction engineer named Konrad Zuse who worked for the Henschel Aircraft Company in Berlin, Germany at the start of WWII. The Z1 made historical developments in floating-point arithmetic and high capacity memory and modules. It was the first of a series of computers including the Z2 and Z3. The Z3 was the world first electronic and fully programmable digital computer, completed in 1941 and made entirely of recycled materials donated by university staff and students. Konrad Zuse also wrote the first algorithmic programming language called "Plankalkul" in 1946. Unfortunately, Zuse could not convince the Nazi government to support his work and his research was discontinued. The Z1 through Z3 models were destroyed during the war including Zuse Apparatebau, the first ever computer company.
