DeWitt Wallace, American publisher, co-founded Reader's Digest (born 1889)

William Roy DeWitt Wallace, publishing as DeWitt Wallace, was an American magazine publisher.

Reader's Digest is an American general-interest family magazine, published ten times a year. Formerly based in Chappaqua, New York, it is now headquartered in midtown Manhattan. The magazine was founded in 1922 by DeWitt Wallace and his wife Lila Bell Wallace. For many years, Reader's Digest was the best-selling consumer magazine in the United States; it lost that distinction in 2009 to Better Homes and Gardens. According to Media Mark Research (2006), Reader's Digest reached more readers with household incomes of over $100,000 than Fortune, The Wall Street Journal, Business Week, and Inc. combined.
