Felix Johannes Erdmann Grüneberg (8 Match 1876 – 15 November 1945)[1] was a German organ builder in Finkenwalde near Stettin.
[1] In 1906, a new organ-building workshop was built in Finkenwalde near Szczecin[1] at Lange Straße 61 (now ul.
Batalionów Chłopskich 61), with a large assembly hall, several workshops and a residence [de], which is the only one of these that has survived to this day.
Grüneberg was a member of the NSDAP after 1933, but according to his grandson, he saved the lives of some Jewish employees by sending them to work in the villages.
The son Barnim Albert Bogislaw Grüneberg (13 April 1914 in Stettin – 24 May 1963 in Munich) learned from his father and in France and was active in the workshop since 1935.
