Ernst Wallfisch (27 May 1920 in Frankfurt am Main – 8 May 1979 in Northampton, Massachusetts) was a prominent viola soloist, recording artist and pedagogue, primarily remembered along with his wife, pianist Lory Wallfisch, as partners of the Wallfisch Duo. Wallfisch was also a master viola da gamba player, even making recordings. Lory Wallfisch donated her husband's collection of viola music, approximately 300 items, to the Primrose International Viola Archive at Brigham Young University.
