Winner of the 1995 Nobel Prize in Literature, Irish poet Seamus Heaney died ten years ago when he was 74. Known for poems that engage with the immediacy of the natural world and its physicality, Heaney spoke to Eleanor Wachtel in 2010 about his book Human Chain. It won UK's £10,000 Forward Prize, among Heaney's many other honours. *This interview originally aired May 23, 2010.
