Raphael David Blau (August 11, 1912 – March 31, 1996) was an American screenwriter who co-wrote the story for Bedtime for Bonzo (1951), among other film productions.
Based on seeing research speculation that a chimpanzee might be able to be raised like a human child, he conceived of the Bedtime for Bonzo story.
He shared a script with his brother-in-law, Ted Berkman, and becoming partners on this and other projects, both received a story credit for the film.
[1][2][3] Fear Strikes Out (1957) about the baseball player Jimmy Piersall brought Blau and Berkman their greatest acclaim.
Their son Joel Blau is a professor at Stony Brook University School of Social Welfare in New York.
