Until 1936, all arithmetic machines were manually operated.Konrad Zuse realized that an automatic-calculating device
would require three basic elements:
- A Control
- A Memory
- A Calculator for the arithmetic
In 1936, he developed a mechanical calculator called the Z1, which was the first binary computer.![]()
In 1946, Konrad Zuse also wrote the first programming language called 'Plankalkul' which he used to program all his computers with.
He also used 'Plankalkul' to program the worlds first chess-playing program.
