Fritz Dietrich (* February 13, 1905 in Pforzheim; † January 1945 near Stablak (East Prussia) was a German musicologist and composer. After one semester at the Technical University of Karlsruhe (majoring in natural sciences), he decided to study musicology. He studied in Freiburg im Breisgau from 1925, in Heidelberg (1928) and for a short time in Leipzig. After receiving his doctorate on the history of the German organ chorale in the 17th century, Dietrich was an assistant at the musicological seminar in Heidelberg from 1931 to 1934. During World War II he was drafted into the Wehrmacht. During 1945, Dietrich was classified as missing in action on the Eastern Front in the area around Heiligenbeil near Stablak (East Prussia, now Poland).
Dietrich wrote music for organ and recorder as well as vocal music, including a Struwwelpeter (shock-headed Peter) cantata. He played the piano, organ, oboe and viola himself.
