Joseph Joachim 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.

Johannes Brahms was a German composer, pianist, and conductor of the mid-Romantic period. Born in Hamburg into a Lutheran family, he spent much of his professional life in Vienna. He is sometimes grouped with Johann Sebastian Bach and Ludwig van Beethoven as one of the "Three Bs" of music, a comment originally made by the nineteenth-century conductor Hans von Bülow.
