Arthur Francis Gresham Leveson Gower was educated at Eton. He was a diplomat and antiquary.
His diplomatic career lasted 30 years. In 1899 he was appointed Secretary to the British Legation at the Hague, where he appears to have come into contact with Whistler, who was ill there for some weeks in 1902 (see #11292).
