Prof Hyman Levy was a Scottish-Jewish philosopher, Emeritus Professor of Imperial College London, mathematician, political activist and fellow of the Royal Society of Edinburgh. Levy was in the Labour Party from 1920 to 1931, and then in 1931 he joined the Communist Party of Great Britain. Despite his theoretical allegiance to the principles of communism, Levy became disappointed by the way the Russian communists treated Jews, and published on the topic, leading to his expulsion from the party in 1958
