Numberphile - The Curta, an amazing old calculator

(6:51) The Curta is a mechanical pocket digital calculator invented by an Austrian Jew by the name of Curt Herzstark. After an eventful development period that included working for the Nazis during WW2, the Curta was introduced in 1948. Curtas were considered the best portable calculators available until they were displaced by electronic calculators in the 1970s.
