Journalist Richard Stengel dedicated a chunk of his career to writing about the great Nelson Mandela. That work resulted in Mandela’s 1993 memoir, Long Walk to Freedom, and two other volumes about the activist and South Africa. His latest work, Mandela: The Lost Tapes (Audible Originals) includes exclusive audio from Stengel’s interviews with Mandela. This never-before-released audio includes 10 episodes that aim to get at the heart of who Mandela was and what shaped him into a revolutionary figure.
