Author of 'The Snow Leopard', co-founder of the Paris Review and the only writer to have ever won the National Book Award for both fiction and nonfiction, Peter Matthiessen was a towering figure of twentieth-century American literary culture. He was also, briefly, an undercover agent for the fledgling CIA; an environmental activist; an advocate for Native American rights and California farmworkers; friends with the likes of Truman Capote and William Styron; and a daring explorer who visited every continent on Earth, scaling the Himalayas and floating through the Amazon on a balsawood raft. This kaleidoscopic biography profiles the life of an American literary giant.
