Salt was born in
Chicago, Illinois, the son of Winifred (née Porter) and William Haslem Salt, an artist and business executive. He graduated from
Stanford University in 1934. The first of the nineteen films he wrote or co-wrote was released in 1937 with the title
The Bride Wore Red. Salt's career in
Hollywood was interrupted when he was
blacklisted after refusing to testify before the
House Committee on Un-American Activities in 1951. Like many other blacklisted writers, while he was unable to work in Hollywood, Salt wrote under a pseudonym for the British television series
The Adventures of Robin Hood. After the collapse of the blacklist, Salt won
Academy Awards for
Best Writing, Screenplay Based on Material from Another Medium and
Best Writing, Screenplay Written Directly for the Screen for his work on
Midnight Cowboy and
Coming Home respectively, as well as earning a nomination for the former for
Serpico. 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. ==Personal life==
