Eric Herz, distinguished Boston harpsichord maker, died on May 25 in Barton, Vermont, after having suffered from Alzheimer's disease for many years. Born in Cologne, Germany, in 1919, Herz emigrated to Palestine in 1939, eventually joining the Israel Philharmonic Orchestra as a player of flute and piccolo. He moved to Canada in 1951, and to Boston in 1953, where he joined the Hubbard and Dowd harpsichord shop before opening his own workshop in 1954. By the time of his retirement in 1996, Herz had produced nearly 500 instruments.
