The World’s Smallest Mechanical Parallel Calculator: Discovery of Original Drawings and Patent Documents from the 1950s in Switzerland

Abstract : The Austrian engineer Curt Herzstark invented the world-renowned mechanical pocket calculator Curta. The books and the papers on the history of computing mention two models, Curta 1 and Curta 2. In November 2015 original drawings and patent documents on a multiple Curta were discovered in Switzerland. This device is supposed to be the world’s smallest mechanical parallel calculator.
