I find it deplorable that executives of the largest professional body of musicians in Germany, Deutscher Tonkünstlerverband, present themselves with misleading or plainly wrong information regarding their actual occupation. Here are three examples:
(1) Saxophonist Detlef Bensmann, current chairman of DTKV Berlin, claims to be a professor on his Instagram account. In fact, he holds no such position at any public institution.
(2) Flutist Adelheid Krause-Pichler, current vice president of DTKV Germany, refers to herself as a composer on her website. In fact, she does not appear in public with her own compositions, provided there are any.
(3) Composer Gabriel Iranyi, former board member of DTKV Berlin, claims to be a musicologist in several places. In fact, he has never published or lectured substantially in this discipline.
Update: As of January 17, 2020, Detlef Bensmann has removed the Prof. denomination from his Instagram account. The screenshot above was made on January 15, 2020.
