Raised in Simcoe and Bradford, Ontario, James Alan Gardner earned Bachelor's and Master's degrees in Applied Mathematics from the University of Waterloo. A graduate of the Clarion West Fiction Writers Workshop, Gardner has published science fiction short stories in a range of periodicals, including The Magazine of Fantasy and Science Fiction and Amazing Stories. In 1989, his short story "Children of the Creche" was awarded the Grand Prize in the Writers of the Future contest. Two years later his story "Muffin Explains Teleology to the World at Large" won an Aurora Award; another story, "Three Hearings on the Existence of Snakes in the Human Bloodstream," won an Aurora and was nominated for both the Nebula and Hugo Awards. He has written a number of novels in a "League of Peoples" universe in which murderers are defined as "dangerous non-sentients" and are killed if they try to leave their solar system by aliens who are so advanced that they think of humans like humans think of bacteria. This precludes the possibility of interstellar wars. He has also explored themes of gender in his novels, including Commitment Hour in which people change sex every year, and Vigilant in which group marriages are traditional. Gardner is also an educator and technical writer. His book Learning UNIX is used as a textbook in some Canadian universities. A Grand Prize winner of the Writers of the Future contest, he lives with his family in Waterloo, Ontario.
