Letters written by Ralph Vaughan Williams to fellow composer Robert Müller-Hartmann between 1938-1950. Müller-Hartmann was a Jewish German composer exiled in England. Vaughan Williams, Imogen Holst and Genia Hornstein helped him find work and establish a new life in a foreign land. Robert Müller-Hartmann was a significant composer in his own right and he also collaborated with Vaughan Williams to help translate some of RVW's works into German.
