Oskar Joost (9 June 1898 - 29 May 1941) was a German musician, who played violin, tenor saxophone and clarinet, as well as directing a dance orchestra.
Joost was born into a musical family in Wissembourg, Alsace on 9 June 1898. His father, Albert Joost, was a cellist in the military. Oskar attended high school in Leipzig and participated in the First World War as a volunteer.
In 1924, Oskar and his brother Ali formed the Oscar Joost Dance Orchestra, with Oskar spelling his name with a 'c' instead of a 'k'. Oscar played first violin, and his brother percussion. From 1930, the Orchestra began playing in the Berlin Eden hotel, which led to a recording contract with Electrola, followed by subsequent contracts with other record labels: Pallas (1931), Crystal (1931-1934), Ultraphon/Telefunken (1932), Grammophon/Polydor (1934-1941). In this time, he was also involved in film work.
In 1933, Oskar Joost joined the Nazi Party, again spelling his name with a 'k'. When Oskar was enlisted in January 1940, his orchestra continued under Rudi Juckeland. Oskar rose to the rank of lieutenant, continuing his musical activities by composing a piece of music for his army unit, a 'Bohemian Polka'. In 1941, he was moved from the Western Front to the Eastern Front, where he was severely wounded. He died in a hospital in Berlin from flu on 29 May 1941.
