Henri Casadesus
Henri Casadesus (September 30, 1879 – May 31, 1947) was a violist and music publisher. He was the brother of Marius Casadesus, uncle of the famous pianist Robert Casadesus, and grand-uncle of Jean Casadesus. He founded the Society of Ancient Instruments with Camille Saint-Saëns in 1901. The society, which operated between 1901 and 1939, was a quintet of performers who used obsolete instruments such as the viola da gamba, or Casadesus's own instrument, the viola d'amore.
