Andrew Sean Greer (born 1970) is an American novelist and short story writer.
He is the bestselling author of The Story of a Marriage, which The New York Times has called an “inspired, lyrical novel,” and The Confessions of Max Tivoli, which was named one of the best books of 2004 by the San Francisco Chronicle and received a California Book Award.
The child of two scientists, Greer studied writing with Robert Coover and Edmund White at Brown University, where he was the commencement speaker at his own graduation, where his unrehearsed remarks, critiquing Brown's admissions policies, caused a semi-riot. After years in New York working as a chauffeur, theater tech, television extra and unsuccessful writer, he moved to Missoula, Montana, where he received his Master of Fine Arts from The University of Montana, from where he soon moved to Seattle and two years later to San Francisco where he now lives. He is currently a fellow at the New York Public Library Cullman Center. He is an identical twin.
While in San Francisco, he began to publish in magazines before releasing a collection of his stories, How It Was for Me. His stories have appeared in Esquire, The Paris Review, The New Yorker and other national publications, and have been anthologized most recently in The Book of Other People, and The PEN/ O. Henry Prize Stories 2009. His first novel, The Path of Minor Planets, was published in 2001.
