The Kraft durch Freude Grösstonorgel(1936)
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.

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. 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.
