His publicist said that Manzarek died Monday at the RoMed Clinic in Rosenheim, Germany surrounded by his family. He had been battling bile duct cancer.
A Chicago native, Manzarek founded The Doors after meeting then-poet Jim Morrison at UCLA film school. The Doors, which also included guitarist Robby Krieger and drummer John Densmore, released their first studio album, The Doors, in 1967. The group went on to sell more than 100 million albums, thanks to iconic hits such as "Hello, I Love You," "Light My Fire" and "Riders on the Storm."
The Doors put out eight more studio albums before Morrison's untimely death in 1971. After that, Manzarek survived as vocalist for a short period of time before the group fell apart. He went on to play in bands including Nite City, and collaborated with "Weird Al" Yankovic and guitarist Roy Rogers in recent years.
However, Manzarek's ties to The Doors remained strong. Kyle MacLachlan played him in the 1991 Oliver Stone biopic The Doors and Manzarek released a best-selling memoir about his experiences, Light My Fire: My Life with The Doors, in 1998. Manzarek also reunited with Krieger to tour as The Doors in recent years.
Manzarek is survived by his wife Dorothy, son Pablo and three grandchildren.
