Fact of the day: the world's first pocket calculator was designed by a concentration camp inmate.
Curt Herzstark's fate seemed to be sealed in 1943 when the Nazis sent him to Buchenwald concentration camp. But then Herzstark, the son of a Jewish industrialist, received the unexpected opportunity to become an Aryan.

The engineer had made a pact with the devil. Night after night, after daily forced labor in the camp, Herzstark made detailed design plans for the world's smallest mechanical calculating machine. He was given special rations as motivation, and he eventually survived the concentration camp. [...]
