Died. Sax Rohmer (pen name for Arthur Sarsfield Ward), about 76, creator of 20th century English fiction's most durable villain: Fu Manchu; after long illness ; in London. Modeled on a mysterious Chinese Rohmer spotted one night in 1913 in the Limehouse fog, wily, sinister Fu Manchu outwitted his Anglo-Saxon pursuers in and out of 13 books and the most exotic parts of the world, assembled a memorable team of Oriental ogres to dispose of his victims, lured such connoisseurs of evil as Boris Karloff and Warner (Charlie Chan) Oland to portray him on screen, almost died horribly at times but was so popular and profitable that he managed to survive and thrive: Rohmer sold him to movies, radio and TV. A mystery himself, Rohmer avoided people, tinkered with spiritualism, in later years wearied of Fu. His last book on Fu (Emperor Fu Manchu) will appear posthumously, fulfilling a prophecy that Fu once whispered to Rohmer's inflamed imagination: "It is your belief that you have made me; it is mine that I shall live when you are smoke."
