Daniel Rubin (1931-December 1, 2015) was a longtime leader of the Communist Party, USA. During the 1960s youths and student upsurge, Rubin served as the CPUSA’s youth secretary. He wrote frequently on various questions of Marxism, Zionism, and anti-Semitism. In 1991, during the tumult of the collapse of the Soviet Union and world socialism, as well as internal divisions within the CPUSA, Rubin – along with Angela Davis, Charlene Mitchell, Herbert Aptheker, and others – left the CPUSA to form the Committee of Correspondence for Democracy and Socialism. However, by 2000 a number of former Communists, including Rubin, began to rejoin the CPUSA.
