He studied under Albrechtsberger, Salieri and Clementi, and was pall-bearer at Clementi’s funeral. Moscheles raised money for his idol Beethoven as he was dying, and translated his biography into English. Moscheles’ extemporised piano-duets with his close friend Meyerbeer were famed. He taught Mendelssohn and his sister as youngsters, the start of an intense lasting relationship with Mendelssohn, the two often playing together in public (Thalberg and Clara Schumann sometimes playing third keyboard). Grieg and Sullivan were also taught by him. Joachim was one among a wide network of Jewish composers and musicians he maintained links with.
