Ewald Kienle

After World War II in 1945, he concentrated on improving and repairing radio and the first television sets.

They were so well constructed that even the Physikalisch-Technische Bundesanstalt (Federal Institute of Physics and Technology) validated it had a lively sound.

[2] Simultaneously, Kienle started to experiment with resonator tubes to improve the sound quality of the loudspeaker.

In Europe, the first digital church organ (Model Kienle PK II),[3] was installed in the European Parliament in Strasbourg in 1985 and was inaugurated with a Bach concert.

During an approximately 50-year period, Kienle installed more than 3,000 organs worldwide: in Europe, South Africa, Peru, and Russia.
