Miss Liebenthal, herself an able violinist, was best known for the lunch hour concerts she ran in the National Gallery of Scotland, from the Second World War until her death in 1970. She was particularly interested in introducing younger musicians to the public, and many of the players and singers she brought to Edinburgh went on to make distinguished careers. The papers deal with the organisation of these concerts, and include Miss Liebenthal's large correspondence with musicians and artists. The remainder of her papers are primarily of family interest. They include letters from her father's relations in Germany, many of whom became refugees before or during the Second World War, and from her own nephews and nieces, one of whom, Geoffrey Lamarque, was Deputy High Commissioner at Engu shortly after Nigeria became independent.
