William Goldman (August 12, 1931 – November 16, 2018) was an American novelist, playwright, and screenwriter. He first came to prominence in the 1950s as a novelist, before turning to screenwriting. He won two Academy Awards for his screenplays, first for the western Butch Cassidy and the Sundance Kid (1969) and again for All the President's Men (1976). His other works include his thriller novel Marathon Man and comedy-fantasy novel The Princess Bride, both of which Goldman adapted for the film versions. Author Sean Egan has described Goldman as "one of the late twentieth century's most popular storytellers. An early draft of No Way to Treat a Lady was read by Cliff Robertson, who hired Goldman to adapt a short story, Flowers for Algernon, for the movies. Before Goldman had even finished the script, Robertson recommended him to do some rewriting on a spy spoof Robertson was starring in, Masquerade (1965). Goldman did that, then finished the Algernon script. However, Robertson disliked it and hired Stirling Silliphant instead to work on what became Charly (1968). Film rights to Boys and Girls Together had been optioned by the producer Elliot Kastner. While they were discussing the novel, Goldman suggested Kastner make a film of the Lew Archer novels of Ross Macdonald, and offered to do an adaptation. Kastner agreed, saying he would option whatever of the novels Goldman suggested; Goldman chose the first, The Moving Target. The result, Harper (1966), was a big hit. Goldman wrote an unfilmed sequel, The Chill.
