Danny Sugerman, who managed the Doors and authored three books on rock ‘n’ roll, died Wednesday after a lengthy battle with lung cancer. He was 50.

Sugerman, an L.A. native, saw the Doors in 1967 and landed a job opening their fan mail when he was 13. He eventually became the band’s co-manager with Jeff Jampol and the Firm. Sugerman would also later manage Iggy Pop, but he worked mostly on Doors projects over the last 30 years.

He wrote the Jim Morrison biography “No One Here Gets Out Alive” in 1981, which became a best seller. He alos penned a rock ‘n’ roll lifestyle tome, “Wonderland Avenue,” and a book on Guns N’ Roses. He was a consultant on Oliver Stone’s film “The Doors.”

Sugerman is survived by his wife Fawn (formerly Fawn Hall), a brother and a sister. Sugerman was active in organizations including the Drug Policy Foundation, Musicians Assistance Program and NARAS’ MusiCares Foundation.
