A television writer who helped shape the voice of The Simpsons during the 1990s, writing episodes including "Lisa the Vegetarian" and coining the invented-but-plausible word "cromulent" for "Lisa the Iconoclast." He went on to co-develop Futurama with Matt Groening, serving as head writer and an executive producer on the animated series' distinctive blend of science-fiction premise and sharp character comedy.
