Howard Duane Allman (November 20, 1946 – October 29, 1971) was an American guitarist, session musician, and founder and leader of the Allman Brothers Band.

The Allman Brothers Band was formed in Jacksonville, Florida in 1969, and achieved its greatest success in the early 1970s. Allman is best remembered for his brief but influential tenure in the band and in particular for his expressive slide guitar playing and inventive improvisational skills. In 2003, he was ranked number 2 in Rolling Stone magazine's list of the 100 greatest guitarists of all time. In 2011, he was ranked number 9. His guitar tone (achieved with a Gibson Les Paul and two 50-watt bass Marshall amplifiers) was named one of the greatest of all time by Guitar Player.
