Gustav Tauschek (April 29, 1899, Vienna, Austria – February 14, 1945, Zürich, Switzerland) was an Austrian pioneer of Information technology and developed numerous improvements for punched card-based calculating machines from 1922 to 1945.
During the years 1926 – 1930 he worked for the Rheinische Metallwaren- und Maschinenfabrik (Rheinmetall) in Sömmerda, Germany, where he developed a complete punched card-based accounting system, which was never mass-produced. The prototype of that system is currently stored in the archives of the Vienna Technical Museum. In the spring of 1928, Rheinmetall created a subsidiary company that was assigned to develop new punched card-based machines. In the fall of the same year, the subsidiary was bought by IBM, thereby assuring its monopoly on the market. Tauschek was awarded a five-year contract and sold 169 patents to IBM in his lifetime.
