Curta Calculators

July 3rd, 2013

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.

"Look, Herzstark," one of the camp commandants said to him, "we know that you are working on a calculating machine. We will permit you to make drawings. If the thing is worth its salt, we'll give it to the Führer after the final victory. He'll certainly make you an Aryan for that."

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. [...]

I'd seen a CURTA Calculator before, but I didn't know the story behind it.
