Mischa Spoliansky (28 December 1898 – 28 June 1985) was a Russian-born composer renowned for his cabaret and revue songs during the Weimar Republic in the 1920s and early 1930s. Born into a Jewish musical family in Białystok, then part of the Russian Empire, Spoliansky's early life was marked by frequent relocations due to family circumstances, including moves to Warsaw, Kalisz, and Vienna. He began his musical education at a young age, studying piano, violin, and cello, and made his public debut at the age of 10.

Following the death of his father, Spoliansky moved to Königsberg and later fled to Berlin in 1914 due to the war. In Berlin, he continued his musical education at Stern'sches Konservatorium while working as a pianist in a coffeehouse. His compositions gained attention, leading to collaborations with notable figures such as Friedrich Hollaender and Werner Richard Heymann. Spoliansky became a significant figure in Berlin's cabaret scene, setting texts by writers like Kurt Tucholsky and accompanying stars such as Marlene Dietrich.

In 1920, under the pseudonym "Arno Billing," he composed "Das lila Lied" (The Lavender Song), considered the first homosexual anthem. Spoliansky's work in musical revues, including "Es liegt in der Luft" and "Zwei Krawatten," showcased his ability to blend American jazz and Argentine tango influences with traditional cabaret music.

The rise of Hitler in 1933 forced Spoliansky to emigrate to London, where he reinvented himself as a composer of film scores, remaining in Britain for the rest of his life. His contributions to music, particularly in the realms of cabaret and film, left a lasting legacy.
