Jules Delsart (24 November 1844 – 3 July 1900)[1] was a French cellist and teacher. He is best known for his arrangement for cello and piano of César Franck's Violin Sonata in A major. Musicologist Lynda MacGregor described Delsart as "one of the foremost French cellists of the period, with faultless technique, a precise bow and a sweet, though not large, tone."[1] He was the owner of the 1689 'Archinto' Stradivari.[1]
