Educated at London's Royal College of Music as well as local universities USC and UCLA, he landed his first motion picture assignments during the 1970s, scoring B-movies like The Lady in Red, Humanoids of the Deep, and Battle Beyond the Stars for producer Roger Corman's New World organization. By 1982, Horner had moved on to major studio fare including 48 Hrs. and Star Trek II: The Wrath of Khan, and four years later he notched his first Academy Award nominations for his score to the science fiction classic Aliens as well as for the song "Somewhere Out There," from the animated picture An American Tail. In 1989, Horner earned a second Oscar nomination for his score to Field of Dreams, that same year winning a Grammy for his work on the Civil War drama Glory; in 1995 he was honored with two more Academy Award nominations, for Braveheart and Apollo 13.

Horner finally struck Oscar gold in 1997, taking home statuettes for his score to the blockbuster Titanic as well as the film's original song "My Heart Will Go On," a hit for Celine Dion. After writing scores for movies like Commando and The New World, Film Music Masterworks: Original Soundtracks, which contained pieces from some of Horner's best-known work (Apollo 13, Braveheart, Willow, and of course, Titanic, among others), was issued in 2006. Horner's output in the 2000s was not nearly as prolific as in the 1990s, but he continued to produce sterling work, earning three further Oscar nominations for A Beautiful Mind (2001), House of Sand and Fog (2003), and Avatar (2009), the colossal success of which almost rivaled that of Titanic. He also wrote the theme to the CBS Evening News program, heard daily by millions of Americans. He continued to be an in-demand presence in film well into the 21st century, scoring big-budget box office smashes like The Amazing Spider-Man and Ender's Game. The year 2012 saw the release of a lavish, four-disc, 25th anniversary edition of his most popular work, Titanic -- the most successful orchestral score album in history. Horner died on June 22, 2015 when the single-engine turboprop aircraft he was piloting alone crashed in California's Los Padres National Forest west of Santa Barbara. He was 61 years old. ~ Jason Ankeny
