The original handheld calculator.
Curta
This was designed in Buchenwald, the German concentration camp, the first prototypes built from the original hand drawings worked. It was manufactured from 1948 till ~1970 when cheap electronic calculators came on the market.
I would love to hold one of these mechanical beauties and feel the gears at work! (Can be had for ~$1000 on Ebay.)
There is a article about the history of the man and the machine in the Jan 04 Sci. Am.
