Philip José Farmer (January 26, 1918 – February 25, 2009) was an American author known for his science fiction and fantasy novels and short stories. He has often written about the pulp heroes Tarzan and Doc Savage, or pastiches thereof: In his novel The Adventure of the Peerless Peer, Tarzan and Sherlock Holmes team up. Farmer’s Lord Grandrith and Doc Caliban series portrays analogues of Tarzan and Doc Savage. It consists of A Feast Unknown (1969), Lord of the Trees (1970) and The Mad Goblin (1970). Farmer has also written two mock biographies of both characters, Tarzan Alive (1972) and Doc Savage: His Apocalyptic Life (1973), which adopt the premise that the two were based on real people fictionalized by their original chroniclers, and connect them genealogically with a large number of other well-known fictional characters in a schema now known as the “Wold Newton family.” Further, Farmer wrote both an authorized Doc Savage novel, Escape from Loki — Wikipedia & the official Philip José Farmer website.
