Ernst Rothauser (7 July 1931 – 4 August 2015)[1][2] was an Austrian computer scientist. As member of Heinz Zemanek's "Mailüfterl-Team", he worked on the country's first transistor computer. After finishing his dissertation he was hired by IBM Zurich Research Laboratory, retiring in 1995.[3][4]
Rothauser owned several patents patented by the IBM Research Laboratory Zurich, including one for a network switches.[7]
