Salt was born in Chicago, Illinois, the son of Winifred (née Porter) and William Haslem Salt, an artist and business executive.[2] He graduated from Stanford University in 1934.[3] The first of the nineteen films he wrote or co-wrote was released in 1937 with the title The Bride Wore Red.
Salt is featured in the extras for the Criterion Collection's Midnight Cowboy blu-ray release, specifically in an audio interview with Michael Childers; many photos of Waldo Salt can be seen here as he was a collaborator for the screenplay. The documentary listed below, Waldo Salt: A Screenwriter's Journey, is also featured on the disc.[citation needed]
Personal life and death
Salt was married four times. The first was to Amber Dana (1938-1941), then to actress Mary Davenport (married in 1942) with whom he had two children, actress/writer/producer Jennifer, and Deborah; both marriages ended in divorce.[5] After his divorce from Davenport, he married Gladys Schwartz in 1969, and remained together until her death in 1981. He was married to playwrightEve Merriam from 1983 until his death in Los Angeles on March 7, 1987; he was 72.[5][6]
The Waldo Salt Screenwriting Award, first presented in 1992, is awarded at the Sundance Film Festival annually. It is determined by the dramatic jury, and recognizes outstanding screenwriting in a film screened at the festival that year.[7]
