Sten Åke Henry "Stan" Hasselgård (October 4, 1922, in Sundsvall, Sweden – November 23, 1948, in Decatur, Illinois, United States)[1] was a Swedish jazz clarinetist.
[3] Under the stage name Stan Hasselgard, he made his acclaimed recording of Swedish Pastry, and in 1948 he joined Benny Goodman's septet, alongside Wardell Gray, Mary Lou Williams and others.
Hasselgård was the "famous bop clarinetist [who] had died in an Illinois car-crash recently" the memory of which spooked Sal Paradise on his journey to Chicago in Jack Kerouac's On the Road (1957).
Hasselgård was second cousin to former Swedish Prime Minister Ingvar Carlsson; their common great-grandparents were Per August Magnusson (1822–1899) and his wife Kristina Charlotta Hjellström (1817–1880).
[5] Hasselgård's niece Åsa Hasselgård-Rowe is married to Richard Rowe, an Australian who served simultaneously as ambassador (2003–2007) to Sweden, Estonia, Finland, Latvia and Lithuania.
