Allen Klein (December 18, 1931 July 4, 2009) was an American businessman, music publisher, writers' representative, filmmaker and record label executive, most noted for his tough persona and aggressive, innovative negotiation tactics, many of which established higher industry standards for compensating recording artists. He founded
ABKCO Music & Records Incorporated. Klein revolutionized the income potentials of recording artists, who previously had been routinely victimized by onerous record company contracts. He first scored massive monetary and contractual windfalls for
Buddy Knox and
Jimmy Bowen, one-hit rockabillies of the late 1950s, then parlayed his early successes into a position managing
Sam Cooke, and eventually managed
the Beatles and
the Rolling Stones simultaneously, along with many other artists, becoming one of the most powerful individuals in the music industry during his era.
