[citation needed] After passing the assessor exam in 1919, he went on to study physics in Heidelberg and Karlsruhe, where he earned his doctorate in engineering.
[citation needed] In this capacity, he was involved in the establishment of the first German radio station, which was based in Berlin's Vox building.
[citation needed] In 1929, he accepted a lectureship at Berlin's Academy of Arts and started the development of the Trautonium, which it would be finished in 1930.
[citation needed] Trautwein started working at the Image and Sound Academy BIKLA in Düsseldorf in 1949, but it quickly closed down.
Subsequently, Trautwein went to the Düsseldorf Conservatory (now the Robert Schumann Hochschule) with his students and established the foundation for a degree in audio and video technology that still exists today.
