Director of the Wallace Collection, London. World War II broke out while he was in Europe. His assistant, Trenchard Cox was left to move the collection into safe hiding. Cox later became the director of the Victoria and Albert Museum. He was the Deputy Director of the Courtauld until 1938 we he was appointed director of the Wallace Collection. Mann astutely brought with him Francis John Bagott Watson, then only the registrar for the Courtauld, but a person of strong self-education.
