Curt Herzstark was born in 1902 in Vienna, and died October 27, 1988 in Nendeln , Liechtenstein. During World War II, Curt Herzstark's plans for a mechanical pocket calculator (the Curta) literally saved his life.
In 1938, while he was technical manager of his father's company Rechenmaschinenwerk AUSTRIA Herzstark & Co. Herzstark had already completed the design, but could not manufacture it due to the Nazi German annexation of Austria. Instead, the company was ordered to make measuring devices for the German army. In 1943, perhaps influenced by the fact that his father was a liberal Jew, the Nazis arrested him for "helping Jews and subversive elements" and "indecent contacts with Aryan women" and sent him to the Buchenwald concentration camp. However, the reports of the army about the precision-production of the firm AUSTRIA and especially about the technical expertise of Herzstark lead the Nazis to treat him as an "intelligence-slave". His stay at Buchenwald seriously threatened his health, but his condition improved when he was called to work in the Gustloff factory linked to the camp. There he was ordered to make a drawing of the construction of his calculator, so that the Nazis could ultimately give the machine to the Führer as a gift after the successful end of the war. The preferential treatment this allowed him ensured that he survived his stay at Buchenwald until the camp's liberation in 1945, by which time he had redrawn the complete construction from memory.
