[REBROADCAST FROM February 23, 2021] For the third installment of our February “Full Bio” series, historian David W. Blight describes what made Frederick Douglass such an engaging speaker that he became one of the most powerful voices in 19th century America. Plus, we look at how the prominent abolitionist’s views on slavery evolved in the 1830’s and 1840’s. Blight’s Pulitzer Prize-winning biography is titled, Frederick Douglass: Prophet of Freedom.
