Embedded Player When Douglas Adams died in 2001 at the age of 49, he left behind a rich body of work including the hugely popular The Hitchhiker's Guide to the Galaxy. The science fiction humor series, which began in 1978 on BBC radio, spawned several books and was later televised. Adams was also working to bring the story to the big screen. NPR's Liane Hansen discusses Adams and The Hitchhikers' Guide with the author's biographer.
