The legendary actor James Earl Jones has died at the age of 93. Across a career that spanned film and stage, he won numerous acting awards and gave voice to iconic characters including Star Wars' Darth Vader and The Lion King's Mufasa. In tribute to Jones, we play an excerpt of his reading of Frederick Douglass's speech What to the Slave Is the Fourth of July?" from a performance of Voices of a People's History of the United States. He was introduced by the late historian Howard Zinn.
