Mark Rudd gained world-wide fame as the leader of the 1968 student uprising at Columbia University, where he was chairman of the school's chapter of SDS, Students for a Democratic Society, the largest radical student organization in the country during the Vietnam War.  Rudd later co-founded the Weatherman faction of SDS, and in June 1969, he was elected national secretary of SDS. In early 1970, he helped found the notorious Weather Underground Organization, dedicated to the violent overthrow of the United States government. He was a fugitive for seven and a half years, surrendering in 1977. Rudd is now a teacher in New Mexico, where he lives with his family.  Mark will talk with Eric Mann, fellow veteran of Students for a Democratic Society, about his years as an activist in SDS, a fugitive in the Weather Underground, and what  reflections and lessons learned from that period can teach movement activists today.
