Jerry Clyde Rubin (July 14, 1938 – November 28, 1994) was an American social activist, anti-war leader, and counterculture icon during the 1960s and early 1970s. Despite being known for holding radical views when he was a political activist, he ceased holding his more extreme views at some point in the 1970s and instead opted for a successful career as a businessman. In the 1960s, during his political activism heyday, he was known for being one of the co-founders of the Youth International Party (YIP) whose members were referred to as Yippies, and standing trial in the Chicago Seven case.
