Josef Slavík

Josef Slavík (also known as Josef Slawjk or Joseph Slawik; 26 March 1806 – 30 May 1833) was a Czech violin virtuoso and composer, who was expected by Viennese musical critics to become Paganini's successor after composing a supposedly unplayable Concerto in F-sharp minor and teaching himself to play Paganini's "La Campanella" after a single hearing.
