Alex North (born Isadore Soifer, December 4, 1910 – September 8, 1991) was an American composer best known for his many film scores. North managed to integrate his modernism into typical film music leitmotif structure, rich with themes. One of these became the famous song, "Unchained Melody". Nominated for fifteen Oscars but unsuccessful each time, North is one of only two film composers to receive the Lifetime Achievement Academy Award, the other being Ennio Morricone.
