Weinstein's niece said her uncle died Sunday at Cabrini Hospital, the New York Times reported Tuesday.
Weinstein collaborated with William Bolcom on four volumes of cabaret songs as well as the operas "McTeague," "A View From the Bridge" with Arthur Miller and "A Wedding" with Robert Altman, the Times said.
He counted poet John Ashberry and painter Larry Rivers among his close friends and worked with Rivers in 1999 on "What Did I Do? The Unauthorized Autobiography."
A playwriting teacher at Yale and Columbia, his satire "The Red Eye of Love" had a long Off Broadway run and his adaptation of "Ovid's Metamorphoses" opened on Broadway in 1971.
He was married and divorced three times. Weinstein is survived by a sister, Gloria, in Greenlawn, N.Y., and four nieces.
