Mark Leyner is an American postmodernist author known for his surreal, high-energy prose, absurd humor, and densely layered narratives. A graduate of Brandeis University and the University of Colorado, Leyner studied under postmodernist Steve Katz and launched his literary career with the short story collection I Smell Esther Williams (1983). He gained a cult following with My Cousin, My Gastroenterologist (1990) and Et Tu, Babe (1992), and continued to experiment with metafiction in novels like The Tetherballs of Bougainville and The Sugar Frosted Nutsack. His writing is characterized by sprawling imagery, extravagant vocabulary, and a wild mix of pop culture, medicine, and satire. Leyner’s nonfiction collaborations with Dr. Billy Goldberg, including Why Do Men Have Nipples?, became bestsellers that blended comedy and real medical facts. He has also worked as a columnist for Esquire and George, written for MTV’s Liquid Television, and co-authored the screenplay for War, Inc.. A lifelong innovator, Leyner has remained a singular voice in American fiction. His more recent books include Gone with the Mind, Last Orgy of the Divine Hermit, and the 2024 retrospective A Shimmering, Serrated Monster!: The Mark Leyner Reader. He lives in New Jersey and continues to influence readers and writers with his singular, genre-defying style.
