Bartolomeo Campagnoli was a violinist and composer from Italy. Campagnoli was a virtuoso violinist who toured Europe spreading the Italian violin form of the 18th century. In 1797, he wrote Metodo per Violino, a treatise on violin playing that can be seen as illustrating the theme of the Baroque and Classical eras. He left the Duke of Courland's court and was named concertmaster of the Leipzig Gewandhaus Orchestra in 1797, a role he held until 1818. In 1801, he went to Paris and was blown away by the violinist Rodolphe Kreutzer's success. During Campagnoli's stay in Leipzig, violinist and composer Louis Spohr, who was in town for a performance, saw Campagnoli present a Rodolphe Kreutzer violin concerto.
