Joel Hirschhorn, 67, who shared two Academy Awards for the theme songs to "The Poseidon Adventure" and "The Towering Inferno," died Sept. 18 at a hospital in Thousand Oaks, Calif., after a heart attack.
Mr. Hirschhorn's songs sold more than 90 million records, were featured in 20 movies and were recorded by artists including Elvis Presley.
With longtime collaborator Al Kasha, he won his first Oscar in 1973 for "The Morning After" from "The Poseidon Adventure," a film about a luxury cruise ship capsized by an enormous wave.
They received another Oscar in 1975 for "We May Never Love Like This Again" from "The Towering Inferno," a film about a catastrophic blaze in a high-rise building.
Mr. Hirschhorn and Kasha were nominated for two Oscars in 1977: for their original score for the Disney animated film "Pete's Dragon" and for the song "Candle on the Water," sung by Helen Reddy in that film.
Mr. Hirschhorn and Kasha also received two Tony Award nominations: in 1981 for their score for the musical "Copperfield" and in 1983 for songs in a revival of "Seven Brides for Seven Brothers."
Mr. Hirschhorn, who was born in the Bronx, N.Y., graduated from High School for the Performing Arts and attended Hunter College. He worked as a nightclub singer and pianist and performed in the rock band the Highlighters before establishing himself as a songwriter.
Survivors include his wife of 20 years, Jennifer Carter Hirschhorn; two stepsons; his mother; a sister; and a grandson.
