George McCulloch retired to the UK a rich man, about 1891. He married his housekeeper,
Mary Agnes Mayger, the widow of an employee at Mount Gipps, in 1893, and they went to live at 184 Queens Gate, London. Between 1893 and his death, in 1907, George became an internationally known art collector and was a patron of the artist
John Singer Sargent. At the time of his death, he owned one of the finest collections of paintings by modern British artists in the world. He made it his rule not to acquire a picture unless it was painted in his own lifetime. An authoritative, well-illustrated text book about the McCulloch collection was published in 2018 by George McCulloch's biographer, Lawrence Robert McCallum (see references). McCulloch died in 1907, the year before his son
Alexander McCulloch won a silver medal in the Single Sculls at the
1908 London Summer Olympic Regatta. George's widow, Agnes, married the Scottish painter
James Coutts Michie in 1908. In 1909, the McCulloch Collection of Modern Art was exhibited at the Royal Academy Winter Exhibition at Burlington House. The bulk of the collection was sold by auction in 1913, with many pictures being purchased by
Viscount Lever. McCulloch's house at Queens Gate was used as a
British Red Cross Voluntary Aid Detachment hospital during the
Great War when it became known as the
Michie Hospital. For her war work, McCulloch's widow, Agnes Coutts Michie, received the
CBE in 1920. In 1928, she donated a painting of George McCulloch by artist
Barnett Samuel Marks to the Broken Hill Art Gallery. ==Citations==
