The "Grösstonorgel" was a vacuum tube oscilator based organ, notable for having been witnessed by Adolf Hitler at the 1936 Olympic games. The "Grosstonorgel" was designed by Oskar Vierling, Winston.E.Kock and the staff of the Heinrich-Hertz-Institut in Berlin. Vierling was an important member of the institute which was responsible for most of the intensive activity in electronic music and musical instruments in Germany in the 1930's.
he Electronic Orchestra of the Heinrich Hertz Institut at the
Berlin Radio Show in 1932. Daily lectures were given by
Prof. Dr. Gustav
Leithauser and his assistant
Wolja Saraga. Up to six
performances took place per day during the 10-day show.
The instruments of the orchestra comprised:
- 2 Theremins (Leon Termen) played by Martin Taubmann and
Tscharikoff
- 1 Trautonium (Dr F Trautwein) played by Oskar Sala
- 1 Hellertion (Helberger and Dr Lertes) played by Helberger
- 1 Neo-Bechstein Grand Piano (Prof Nernst and Bechstein/Siemens)
played by Narath and Padua
- 1 Electric Grand Piano (Oskar Vierling) played by Frl Wolfsthal
- 1 Electric Violin (Oskar Vierling) played by Frau Sugowolski
- 1 Electric Cello (Oskar Vierling) played by Dr Reinhold
Vierling's previous work had been designing electro-acoustic instruments such as an electric Cello and Violin, the electro-acoustic Elektrochord and assisted in the development of the Neo-Bechstein-Flügel. The Neo-Bechstein-Flügel was essentially an electro-acoustic adaption of a Bechstein grand piano. The vibrations of the strings were amplified through magnetic pickups and coloured using a simple filter system. Oskar Vierling also assisted Jörg Mager in the construction of the Klaviatursphäraphon at Darmstadt.

Other designers who studied at the Heinrich-Hertz-Institut included Harald Bode, designer of the
Warbo Formant Organ and the
Melochord. The institutes director Karl W.Wagner was himself responsible for half of the electronic instruments built in Germany during the 1930's and developed a voice synthesiser that influenced the work in the USA on the
Voder and Vocoders in the 1940's.
