Joining us to discuss Marable’s accomplishments and his final work are Michael Eric Dyson, Professor of Sociology at Georgetown University, and Melissa Harris-Perry, Associate Professor of Politics and African-American studies at Princeton University. Marable considered "Malcolm X: A Life of Reinvention" book his life's work. It is the definitive account of Malcolm X drawn from primary sources, explains Michael Eric Dyson.
