Paul Nash (1889-1946) played a key role in the development of Modernism in English art. He was among the most important landscape artists of the first half of the twentieth century, and the artworks he produced during World War I are among the most iconic images of the conflict. Nash attended the Slade School of Art, where the remarkable generation of artists who studied under the influential Henry Tonks (1862-1937) included, too, Harold Gilman (1876-1919), Spencer Gore (1878-1914), David Bomberg (1890-1957), Stanley Spencer (1891-1959), Mark Gertler (1891-1939), and Roger Hilton (1911-1975).
