Claus-Frenz Claussen, (originally: Claußen) (28 May 1939 – 4 September 2022) was a German ENT-Medician and University teacher, author, editor, artist and inventor.

[1] During his academic years, he attended courses at the universities of Toulouse (France), Oxford (England), Oslo (Norway), Göteborg (Sweden), Copenhagen and Århus (Denmark), as a scholarship holder of the Studienstiftung des deutschen Volkes.

[2] His postdoctoral thesis was about the recording and evaluation of selected quantitative equilibrium function tests ("Über die Aufzeichnung und Auswertung ausgewählter quantitativer Gleichgewichtsfunktionsprüfungen“).

Analysis of the data made it possible to draw conclusions about diseases such as vertigo and double vision, and hearing disorders or tinnitus.

Claussen has organized and conducted a lot of international congresses, which often take place in his home town of Bad Kissingen, about neurotology and disorders of the cranial senses as well as their therapy.

This invention is named after him, the "Auto-Cyberno-Mobil“, and is designed to maintain the mobility of the increased elderly population, as a consequence of demographic transition.
