Bill Berkeley is a former reporter and editorial writer for The New York Times and the author of The Graves Are Not Yet Full -- Race, Tribe and Power in the Heart of Africa (2001).

Prof. Berkeley has just returned from his second journey to Iran this year. He will give an update on his current book project, a reexamination of the Iran hostage crisis as seen from the vantage point of a generation later. He is focusing on the surviving Iranian hostage-takers, some of whom have emerged in middle age as leading figures in Iran's embattled reformist movement, in vehement opposition to the ruling mullahs in whose name they acted in their youth.

The talk was videotaped and can be viewed at http://www.columbia.edu/cu/news/media/04/291_iran_hostage_crisis_reform
