His academic positions included Syracuse University, New England Conservatory, Boston University and Boston Conservatory, and his voice clients included President John F. Kennedy, President Lyndon B. Johnson, Gov. Michael S. Dukakis, sportscaster Curt Gowdy, actors Faye Dunaway, Al Pacino, Jill Clayburgh and Ruth Gordon, and folksinger Joan Baez.
