James or Jim Morrison (3 May 1893 – 1947), known as "The Professor", was a notable South Sligo-style Irish fiddler.
Morrison grew up in a community steeped in traditional Irish culture especially music and at the age of 17 he was employed by the Gaelic League to tutor the Connacht style of step dancing at the Gaelic League school in County Mayo.
Morrison become associated with other leading Irish musicians such as Michael Coleman, Paddy Killoran who were also from County Sligo.
This repertoire included predominantly reels, rather than jigs and hornpipes, and were often played by Irish musicians in the same order as on the original recordings.
According to Seamus MacMathuna, "More than thirty years after Coleman's death ... one seldom hears 'Bonny Kate' without 'Jenny's Chickens'.
