Ernst Rothauser

Ernst Rothauser (born July 7, 1931 in Vienna ; † August 4, 2015 in Reichenburg ) was an Austrian scientist. As a member of the so-called “Mailüfterlteam” of the computer pioneer Heinz Zemanek , Rothauser worked on Austria's first transistor computer . After completing his dissertation, Rothauser was hired by the IBM research laboratory in Zurich . Rothauser worked there until his retirement in 1995.

life and work

Ernst Rothauser was married to Erni Rothauser. The daughter Veronika and son Martin emerged from the marriage, and they are also active in the IT sector today.

Team Mailüfterl

Team Mailüfterl

Starting in 1954, Heinz Zemanek and a team of students developed the Mailüfterl , the first transistor computer in Europe. This team included:

dissertation

In 1960 Ernst Rothauser completed his dissertation on vocoder at the Technical University of Vienna . The vocoder, part of the Siemens synthesizer , was available for musical use for the first time in the early 1960s. Towards the end of the 1970s, vocoders became popular as a commercially produced effects device or stand-alone instrument equipped with a keyboard.

Further scientific work

Rothauser has a number of patents that were patented as part of his scientific work in the IBM research laboratory. An outstanding patent dates from 1980 and deals with switches . Switches became widespread in the late 1990s and early 21st century as the need for fast networks increased rapidly.
