The podcast description goes:
Journalist, broadcaster, and bestselling author, Simon Winchester, tells the remarkable story of Joseph Needham, an eccentric English chemist who wrote a vast book on Chinese science which remains the longest book about China ever written in the English language. Winchester's lecture on The Man Who Loved China was delivered at the Royal Ontario Museum on October 14, 2010.
This should be enough, but let me add that apart from Joseph Needham coming alive and having us share his fascination with China, also Winchester comes alive. He manages to take you in with his fascination for Needham and has some spectacular tales about the road to his book.
