Casimir Oberfeld (16 November 1903 – January 1945) was a Jewish Polish-born French composer. He worked on many film scores and also wrote popular songs of the 1920s and 1930s. Following France's invasion by Germany in 1940 during the Second World War, Oberfeld faced increasing persecution. Having taken shelter in Italian-occupied Nice he was arrested when the area was taken over by the Germans. He was sent to Auschwitz where he died in January 1945
