The Helland family from Bø in Telemark is a Norwegian dynasty of Hardanger fiddle makers who made the most significant and important contribution to the development of the Norwegian Hardanger fiddle tradition. The celebrated Norwegian fiddler Ole Bull played on Helland fiddles. During nearly 200 years and four generations the family counted 14 fiddle makers, many of them among the most important in the fiddle-maker tradition in Norway. It may well be the largest fiddle maker family in history.
