Franz Mittler (April 14, 1893 in Vienna – December 28, 1970 in Munich) was an Austrian (and later on an American) composer, musician, and humorist.
His maternal grandmother financed his earliest musical education which started out under Mr. Deutsch and later Oscar Stock (violin).
He studied theory with Joseph Labor (also teacher of Julius Bittner and Arnold Schoenberg), later composition with Richard Heuberger and Karl Prohaska.
Further studies included Fritz Steinbach and Carl Friedberg at the Vienna University and the Conservatory in Cologne.
In 1913 Mittler volunteered for a one-year stint in the Imperial and Royal Austrian Army in the supply and logistics division.
