Sir Sidney Robert Nolan OM, AC (22 April 1917 – 28 November 1992) was one of Australia's leading artists of the 20th century. 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.
