  Klaus von Bismarck
from 1961 - 1976 head of the WDR
(West German Broadcasting) in Cologne
  Prof. Dr. Rudolf Haase
Founder of the Hans Kayser Institute for Fundamental Harmonical Research at the University of Music & Performing Arts Vienna
In the 60ies the great musicologist and renowned researcher in the field of the microcosm of music, Marius Schneider, was head of the Institute of Musicology of the University of Cologne; Rudolf Haase, the present living great expert for the investigation into the laws of harmony was his student. At that time Peter Hübner conducted research in the Phonetic Institute of the university which was affiliated to Professor Schneider’s institute and it was through him that Peter Hübner directed his attention profoundly to the aspect of what is harmonical in music: to the laws of harmony, and Marius Schneider inspired him to investigate them on his own.
Professor Schneider produced at that time also a rather extensive program in the WDR (West German Broadcasting) regarding the harmony laws of the microcosm of music and their application by the different ethnic peoples of the world – especially in Africa.

Interestingly, the head of this biggest radio and television broadcasting station of Germany, Klaus von Bismarck, personally made it possible for Peter Hübner, in a very unconventional way, to produce copies of his opera score “Fluch oder Segen: doch” (Curse or Blessing: yet) in the WDR.
