James Douglas "Jim" Morrison (December 8, 1943 – July 3, 1971) was an American singer, songwriter and poet best remembered as the lead singer of The Doors. Due to his songwriting, baritone voice, wild personality and performances, he is regarded by critics and fans as one of the most iconic and influential frontmen in rock music history, and, due to the dramatic circumstances surrounding his life and death, in the latter part of the 20th century, he was one of the popular culture's most rebellious and oft-displayed icons, representing generational gap and youth counterculture. He was also well known for improvising spoken word poetry passages while the band played live. Morrison was ranked number 47 on Rolling Stone's list of the "100 Greatest Singers of All Time", and number 22 on Classic Rock Magazine's "50 Greatest Singers In Rock".Ray Manzarek said that Morrison "embodied hippie counterculture rebellion..." Morrison was sometimes referred to by other monikers, such as "Lizard King" and "King of Orgasmic Rock". Morrison developed an alcohol dependency. He died at the age of 27 in Paris, probably of an accidental heroin overdose. No autopsy was performed, and the exact cause of Morrison's death is still disputed. Jim Morrison's grave is located at Père Lachaise cemetery in eastern Paris.
