Abbot Howard "Abbie" Hoffman (November 30, 1936 – April 12, 1989) was an American social and political activist who co-founded the Youth International Party ("Yippies"). Later he became a fugitive from the law, living under an alias and working as an environmentalist following a conviction for dealing cocaine. Hoffman was arrested and tried for conspiracy and inciting to riot as a result of his role in protests that led to violent confrontations with police during the 1968 Democratic National Convention, along with Jerry Rubin, David Dellinger, Tom Hayden, Rennie Davis, John Froines, Lee Weiner and Bobby Seale. The group was known collectively as the "Chicago Eight"; when Seale's prosecution was separated from the others, they became known as the Chicago Seven. Hoffman came to prominence in the 1960s, and continued practicing his activism in the 1970s, and has remained a symbol of the youth rebellion and radical activism of that era.
