About Jerry Rubin
Jerry Clyde Rubin 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. Before returning to social and political activism, Rubin made a visit to Havana, to learn first-hand about the Cuban revolution. Rubin turned his attention to political protest, his first in Berkeley, protesting against the refusal of a local grocer to hire African Americans.
