Robert Ingersoll Wilder (January 25, 1901 in Richmond, Virginia ? August 22, 1974) was an American novelist, playwright and screenwriter. The son of a minister-turned-lawyer-turned-doctor-turned-dentist who was still going to college when his son was born, Wilder's childhood was spent at Daytona Beach, Florida. Following a stint in the U.S. Army during World War I, he was educated at Stetson University and Columbia University. At various times in his life, Mr. Wilder was a soda jerk, a ship fitter, a theater usher, a shipping clerk, a newspaper copyboy, a publicity agent (Claudette Colbert was among his clients), a radio executive, and a journalist (for The New York Sun).

Mr. Wilder traveled widely and contributed stories to The New Yorker, among other magazines. He was author of two plays, Sweet Chariot, based on the life and career of African-American activist Marcus Garvey, and Stardust, both produced on Broadway. He also wrote the screenplay for the epic Western, The Big Country, in 1958.

His novel, Written on the Wind (1945) was adapted into a movie of the same name in 1946. It was directed by Douglas Sirk and starred Rock Hudson, Lauren Bacall, Robert Stack and Dorothy Malone.
