David Ritz (born December 2, 1943 in New York City) is an American author. He has written novels, biographies, magazine articles, and over a hundred liner notes for artists such as Aretha Franklin, Ray Charles, and Nat King Cole. He has coauthored 36 autobiographies, including some celebrities’ autobiographies.

As a journalist - “Happy Song: Soul Music in the Ghetto,” Ritz’s first critical essay, was published in Salmagundi (1970). Dozens of other articles have followed, including “History of the Jews of Dallas,” D Magazine (1974); “Kids’ Stuff: Jackson Pollock, Jimmie Vaughan and the Architecture of Las Vegas,” Art Connoisseur (1998); “Show and Tell,” introduction to Rolling Stone’s Tattoo Nation (2002); the forward to Lady Sings the Blues, the 50th-anniversary edition of the autobiography of Billie Holiday (2006); and “The Last Days of Brother Ray,” included in Da Capo's Best Music Writing of 2005.

As a biographer - Ritz’s first collaboration was Brother Ray (1978), the autobiography of Ray Charles. Ritz has said that his initial intention was to write a biography until becoming intrigued by the idea of rendering the book entirely in Charles' voice. "That's when I discovered I had a gift for channeling voice", Ritz told the L.A. Times' Patrick Goldstein in 2012. "That discovery changed the course of my literary life."

As a novelist - Ritz’s fiction ranges from sports fantasies--The Man Who Brought the Dodgers Back To Brooklyn (1981)-- to jazz fantasies--Blue Notes Under a Green Felt Hat (1989) and Barbells and Saxophones (1989). Ritz collaborated with Mable John on three Christian novels: Sanctified (2006), Stay Out of the Kitchen (2007) and Love Tornado (2008). He has also collaborated with rapper T.I. on two novels— Power and Beauty (2011) and Trouble and Triumph (2012).

Ritz graduated from the University of Texas in Austin, Phi Beta Kappa (1966) and received a Masters of Arts from the State University of New York at Buffalo (1970) where he studied with literary critic Leslie Fiedler.[citation needed]
