Philip José Farmer R.I.P

Philip José Farmer (January 26, 1918 - February 25, 2009) passed away. I read a lot of his stuff in the 80's. I really liked the first four Riverworld books. It was mostly his take on historical persons like Richard Burton, the explorer not the actor, and Samuel Clemmens that attracted me to the series. Can't say I liked his other works much. Rest in Peace.
