Bio:Marshall Ganz played a key role in shaping Barack Obama’s 2008 campaign. He is a lecturer in Public Policy at the John F. Kennedy School of Government. In 1964, a year before graduating, he left to volunteer as a civil rights organizer in Mississippi. In 1965, he joined Cesar Chavez and the United Farm Workers; over the next 16 years he gained experience in union, community, issue, and political organizing and became Director of Organizing. During the 1980s, he worked with grassroots groups to develop effective organizing programs, designing innovative voter mobilization strategies for local, state, and national electoral campaigns. In 1991, in order to deepen his intellectual understanding of his work, he returned to Harvard College and, after a 28-year “leave of absence,” completed his undergraduate degree in history and government. He was awarded an MPA by the Kennedy School in 1993 and completed his PhD in sociology in 2000. He teaches, researches, and writes on leadership, organization, and strategy in social movements, civic associations, and politics.
