Franchomme’s student at the Conservatoire Jules Delsart (1844–1900) succeeded him upon his death. Delsart’s interest in the viola da gamba and its music led him to found the Societé des Instruments Anciens, which performed all over Europe. In 1891 in London, Delsart, Popper, and Edward Howell premiered Popper’s Requiem for three cellos and orchestra, written in memory of Popper’s friend and publisher Daniel Rahter.
