Joseph Joachim (28 June 1831 – 15 August 1907) was a Hungarian violinist, conductor, composer and teacher who made an international career, based in Hanover and Berlin. A close collaborator of Johannes Brahms, he is widely regarded as one of the most significant violinists of the 19th century. Joachim quit service in Hanover in 1865, and the family moved to Berlin, where he was entrusted with founding and directing a new department at the Royal Conservatory, for performing music. He formed a string quartet, and kept performing chamber music on tours. His playing was recorded in 1903.
