"Romberg's career as a violinist can hardly been separated from that of his cousin Bernhard... His symphonies, string quartets, and quintets with flute or clarinet are original and independent. Works in other genres... have been underestimated. Romberg's craftsmanship is evident not only in obligato writing but also in his mastery of strict counterpoint, which he uses against the prevailing trend of his time." Klaus G. Werner in MGG2.
