Swedish bandleader, pianist, vibraphonist and composer, born June 18, 1919 in Stockholm, died December 08, 1988 in Stockholm.

He wrote his first composition as a 16-year-old. He studied music with Stig Holm. He was involved in the dance orchestra White Star in 1935–1936 and later played with several orchestras including Sten Axelson, Miff Görling, Håkan von Eichwald, Charles Redland, Arne Hülphers, Arthur Österwall and Simon Brehm. He formed his own orchestra in 1949. The band was guested by the American saxophonist James Moody in October 1949, and disc recordings were made in which, among others, Swanerud participated. I’m in the mood for love with piano solo by Swanerud, was a great success, not least in America, and is today considered a jazz classic. He was awarded the SKAP scholarship in 1975.
