William Orpen Portrait of Miss Sinclair

William Orpen (1878–1931) was an Irish artist who worked mainly in London. Orpen was a fine draughtsman and a popular, commercially successful painter of portraits for the well-to-do in Edwardian society, though many of his most striking paintings are self-portraits. During World War I, he was the most prolific of the official war artists sent by Britain to the Western Front.
