Isaac Rab (1893 Ð 1986) was a well-known agitator for Socialism in the Boston area, as a soap-box orator, a lecturer and a teacher, for most of the Twentieth Century. He was among the founding members of the World Socialist Party and organized a Boston Local in 1932, in which he was a central figure for many years. Today the WSP(US) remains a companion party of the World Socialist Movement.
