On July 5, 1880 Czech violinist and composer Jan Kubelik was born. 

Sixty years before the Beatles, the similarly mophaired Jan Kubelík took the musical world by storm, becoming the pin-up boy of the violin.

Kubelík has an equivocal place in violin history. He is acknowledged as a key figure in advancing technique, showing how cleanly and precisely the violin could be played and stressing that runs and scales should be practised slowly and brought up to speed only when the notes are thoroughly and evenly mastered (though this precept came from Ševčík). 

It was pointed out by Joseph Szigeti, however, that Kubelík hewed to a more old-fashioned style than Kreisler, Elman and Heifetz, who could caress a phrase in a way foreign to Kubelík. Musically, too, he had limitations, though Carl Flesch was wrong in diagnosing a lack of chamber music experience. Like all Prague Conservatoire alumni in the era of Bennewitz and Wihan, Kubelík knew and loved the chamber literature: in London in the early 1900s he even led a quartet including the cellist Paul Grümmer.
