Born in Florence of American parents, John Singer Sargent (1856-1925) studied in Paris until 1884, the year he first achieved fame with his provocative portrait of Mme Gautreau (Metropolitan Museum of Art, New York), first exhibited as Madame X. His bravura handling of paint (developed through a close study of Velazquez and Hals) won him great success as a portraitist, both in the United States, and in Britain, where he came to live after Paris. He was a friend of Monet, whom he painted around 1885 (Tate Gallery, London). In 1907 he gave up his successful portrait practice and, apart from a few distinguished exceptions (for example, his friend Henry James, 1913, National Portrait Gallery, London, and President Woodrow Wilson, 1917, National Gallery, Dublin), he devoted himself to landscapes, murals and watercolours from his travels. As an official War Artist in the First World War (1914-18), he produced the powerful and monumental Gassed (1918, Imperial War Museum, London).This fresh, bright but uncharacteristically personal watercolour shows the view from Sargent's hotel, with the artist's sketchbook and paintbox propped open by the window.
