Hanning Schröder (born Hans Schröder; 4 July 1896 – 16 October 1987) was a German composer and violist. From 1927, he worked in Berlin as a violist in orchestras for opera, radio and film, and in the Havemann String Quartet of his teacher Gustav Havemann. He formed the Harlan Trio with his wife and violinist Peter Harlan, performing Renaissance and Baroque music as pioneers of historical instruments. Due to his wife's Jewish descent, he had to stop working under the Nazi regime from 1935. They hid a Jewish couple in the house in Berlin that they left for safety reasons, earning them a Righteous Among the Nations recognition. As a composer, Schröder is known for chamber music, especially a string quartet based on the song of the Moorsoldaten from the Börgermoor concentration camp.
