From 1961 to 1965 Richard and John studied in London with the English pianist, Dame Myra Hess, who prepared them for their professional debut in London's Wigmore Hall on October 27, 1962. Its success led to recitals on the Continent, especially in the Netherlands, where they received enthusiastic critical acclaim, and to a contract to tour in the United States under the aegis of impresario Sol Hurok.
