John Challis (1907–1974) was a pioneering American builder of harpsichords and clavichords, recognized as the only harpsichord maker in the United States at one time. He apprenticed in England with Arnold Dolmetsch and later established his workshop in Ypsilanti, Michigan. Challis's instruments featured innovative materials like aluminum and brass, leading to unique tonal qualities and stability. Renowned for his craftsmanship, Challis influenced future makers, although his work represents a shift away from traditional historical construction methods toward modern technology in instrument making.
