Frederik Pohl is 93 years old, and apart from a few years in the 1940s, when he was busy defeating Adolf Hitler with the assistance of the U.S. Army Air Force, has been involved in science fiction activities since the age of 11.
First he was a compulsive reader of sf magazines, then a faan who was a publisher of fanzines and a member and sometimes organizer of six or seven fan clubs in the New York area, including the fabled Futurians. At 16, he took part in the first sf con ever, in Philadelphia in 1936.
At 19, he became the editor of two professional sf magazines, and somewhere in that period he began writing sf., by now having published some 60 or 70 novels, half of them written alone and the other half being collaborations with C.M. Kornbluth, Jack Williamson, Isaac Asimov, Arthur C. Clarke and several other writers. He has received six Hugos, three Nebulas and forty or fifty other awards, some of which he has given himself.
Meanwhile he can be read in his blog, The Way the Future Blogs.
