Poul Anderson (1926-2001) grew up bilingual in a Danish American family. After discovering science fiction fandom and earning a physics degree at the University of Minnesota, he found writing science fiction more satisfactory. Admired for his "hard" science fiction, mysteries, historical novels, and "fantasy with rivets," he also excelled in humor. He was the guest of honor at the 1959 World Science Fiction Convention and at many similar events, including the 1998 Contact Japan 3 and the 1999 Strannik Conference in Saint Petersburg, Russia. Besides winning the Hugo and Nebula Awards, he has received the Gandalf, Seiun, and Strannik, or "Wanderer," Awards. A founder of the Science Fiction & Fantasy Writers of America, he became a Grand Master, and was inducted into the Science Fiction and Fantasy Hall of Fame.
In 1952 he met Karen Kruse; they married in Berkeley, California, where their daughter, Astrid, was born, and they later lived in Orinda, California. Astrid and her husband, science fiction author Greg Bear, now live with their family outside Seattle.
