Zuse Computers

Z22 electronischer programm-rechenautomat

Despite early unreliability, Zuse’s vacuum tube Z22 became a workhorse for academic and industrial research. Zuse sold 56 in the face of fierce competition from IBM.

Zuse Computers

A computer in every engineering office. That was the vision of Germany’s Konrad Zuse, who in 1936 began developing his Z1 computer, the first of a series.

After World War II, Zuse rescued his unfinished Z4 from bombed-out Berlin and regrouped. A Swiss university installed the completed Z4 in 1950, continental Europe’s only computer.

The transistorized Z23 was a compatible successor to the vacuum tube Z22. It was an even bigger success: 98 units were made.
