On invitation by Anton Rubinstein, Wieniawski moved to St. Petersburg where he stayed until 1872. There, he taught a large number of violin students, led the Russian Musical Society's orchestra and string quartet. Fro, 1872 to 1874, Wieniawski toured throughout the United States together with Rubinstein and in 1875, he replaced Henri Vieuxtemps as a violin teacher at the conservatory of Brussels.
