Sir Sidney Robert Nolan (22 April 1917 – 28 November 1992) was one of Australia's leading artists of the 20th century. Working in a wide variety of mediums, his oeuvre is among the most diverse and prolific in all of modern art. He is best known for his series of paintings on legends from Australian history, most famously Ned Kelly, the bushranger and outlaw. Nolan's stylised depiction of Kelly's armour has become an icon of Australian art.
Ernst Ludwig Kirchner (6 May 1880 – 15 June 1938) was a German expressionist painter and printmaker and one of the founders of the artists group Die Brücke or "The Bridge", a key group leading to the foundation of Expressionism in 20th-century art. He volunteered for army service in the First World War, but soon suffered a breakdown and was discharged. His work was branded as "degenerate" by the Nazis in 1933, and in 1937 more than 600 of his works were sold or destroyed.
