Zuse worked on his computer concept after work at night.

The invention of the world's first fully programmable electronic computer didn’t  become a great sensation at that time.

He used plastic sheets to make mechanical switches.

Konrad Zuse worked at the Heinkel Aircraft Company where he tried to calculate the effect of wind on airplane wings.

Konrad Zuse was able to find the idea how to physically represent ones and zeros in a machine.

The computer was finished in December 1941.

Konrad Zuse replaced the cumbersome mechanical switches with relays from old telephones.

The inventor cooperated with his colleagues to develop the idea of such machine.

Konrad Zuse thought very few people might need a machine that could do complex calculations without having to input every tiny detail by hand.

In 1939 Konrad Zuse was called up to war and headed for the frontlines.
