Franz Mück (born October 3, 1898 in Vienna, Austria-Hungary; died November 3, 1957 in Bad Reichenhall) was a German jazz pianist, composer and arranger.
Franz Mück studied music and began composing in 1920. He worked in Oscar Joost's orchestra in Berlin from 1930; further recordings were made in that decade with Richard Forst, Eugen Wolff and Erwin Steinbacher. In the early 1940s, he played in Berlin with Hans Georg Schütz, Theo Reuter, Kurt Wege, Albert Vossen, Henk Bruyns, Horst Winter, Charlie and His Orchestra, Erhard Bauschke, Georg Trapp, Willi Stech, and Heinz Wehner. He wrote hot jazz-oriented dance music such as "Große Eile", and "Hallo Benny", as well as light music and hits such as "Storchenparade", "All meine kleine Wünsche", "Junger Mann im Frühling" (with Bruno Balz and Will Meisel), "Carlton" "Tanzstück 1742", "Maskerade" and "Anaconda", furthermore five chamber music oriented novelettes for six instruments, as well as numerous arrangements, e.g. for dance orchestra by Oscar Joost ("Tango Apasionado"), Willi Stech and Otto Kermbach. He also led his own ensemble, in which, among others, the pianist Helmuth Wernicke played. In the field of jazz, he was involved in 88 recording sessions from 1930 to 1944.
Mück was on the ''Gottbegnadeten list'' (God-gifted list or Important Artist Exempt List) of the Nazi Reich Ministry for Popular Enlightenment and Propaganda in 1944.
After the end of the war, Mück played as a jazz pianist in various clubs of the American occupation forces. He then moved to Salzburg and later to Bad Reichenhall.
