Lanford Wilson, an American playwright who won the Pulitzer Prize for his play Talley’s Folly and whose work often broke ground in the depiction of homosexuality, died today of complications from pneumonia, according to the New York Times. He was 73. Born in Lebanon, Mo., Wilson co-founded the off-Broadway theater company the Circle Repertory Company, which debuted several of Wilson’s plays, including The Hot l Baltimore (1973), Fifth of July (1978), and Talley’s Folly (1980), a one-act play set in real time about a man and a woman deciding whether to get married.
