CURTA Calculator
Contina AG Mauren

Notes: See Wikipedia Entry on Curta Calculators
1) Austrian Curt Herzstark designed this calculator while imprisoned in a Nazi concentration camp during WWII. Soon after the war, Herzstark established a factory in Liechtenstein with the backing of the Prince of Liechtenstein. The device, a very small and highly sophisticated calculating machine, was based on Leibniz's stepped drum concept. Herzstark called his invention "Curta", a name he had wanted to give the daughter he never had.
2)Production was started at April 1, 1947. In 1966 CONTINA AG was bought by the firm HILTI AG in Schaan. Production was stopped on November 1970. CURTAs were sold until early 1973. There are +/- 80000 Curta I and +/- 60000 Curta II machines. Curt Herzstark heard 150,000 to 160,000, maybe even more CURTAs were manufactured.


ISRM CURTA Type I

Owned by Ward Anthony, Littleton, Colorado. Provided by his son Russell Anthony
Ward Anthony was an aerospace engineer at Martin Marietta in Littleton, Colorado and worked on many of the launch systems. He used this CURTA in his profession as well as while competing in car rallye's
