Ole Bull 1810-1880
One of the greatest violin virtuosos of his time.
He was a violin solist of international repute. Born in Bergen, he travelled all over Europe and North America to give concerts. He sought to make the folk musik and culture of Norway more widely known. As a violin virtuoso, he was widely acclaimed for his brilliant improvisations, and for the rich tone of his play. Around 1860 he conceived the idea of a Norwegian Academy of Folk Music, but was never able to gain public sponsorship for this project.
