Philip José Farmer was born on January 26, 1918 in Terre Haute, Indiana, USA. He’s famous especially for his science fiction cycles such as the World of Tiers and Riverworld and for other works that were controversial due to their sex and religion themes.

In the last phase of his career, Philip J. Farmer lost much of his innovative and iconoclastic strength but at that point certain taboos had been eliminated from the world of science fiction and part of the merit is his. The author died on February 25, 2009 leaving an important legacy and not only in the field of science fiction and fantasy.
