Manny Nosowsky (born January 1932, in San Francisco, CA) is a U.S. crossword puzzle creator. A medical doctor by training, he retired from a San Francisco urology practice and, beginning in 1991,[1] has created crossword puzzles that have been published in The New York Times, the Wall Street Journal, and many other newspapers. Will Shortz, the crossword puzzle editor for The New York Times, has described Nosowsky as "a national treasure"[1] and included four Nosowsky puzzles in his 2002 book Will Shortz's Favorite Crossword Puzzles.[2] Since Shortz became editor of the Times crossword in November 1993, Nosowsky has published nearly 250 puzzles there, making him by far the most prolific published constructor in the Times. [2] Nosowsky is frequently chosen to produce puzzles for the American Crossword Puzzle Tournament.[3]
