Sir Sidney Robert Nolan (22 April 1917 – 28 November 1992) was one of Australia's best-known painters and printmakers.
Sidney Nolan was born in Carlton, an inner working-class suburb of Melbourne, on 22 April 1917. He was the eldest of four children. His parents, Sidney (a tram driver) and Dora, were both fifth generation Australians of Irish descent. Nolan later moved with his family to the bayside suburb of St Kilda. He attended the Brighton Road State School and then Brighton Technical School and left school aged 14. He enrolled at the Prahran Technical College (now part of Swinburne University), Department of Design and Crafts, in a course which he had already begun part-time by correspondence. From 1933, at the age of 16, he began almost six years of work for Fayrefield Hats, Abbotsford, producing advertising and display stands with spray paints and dyes. From 1934 he attended night classes sporadically at the National Gallery of Victoria Art School.
Nolan was a close friend of the arts patrons John and Sunday Reed, and is regarded as one of the leading figures of the so-called "Heide Circle" that also included Albert Tucker, Joy Hester, Arthur Boyd and John Perceval. Boyd and Perceval were members of the Boyd family who were centered at "Open Country", Murrumbeena.
In 1938, he met and married his first wife Elizabeth, but his marriage soon broke up because of his increasing involvement with the Reeds. He joined the Angry Penguins in the 1940s, after deserting from the army during World War II.
He lived for some time at the Reeds' home, "Heide" outside Melbourne (now the Heide Museum of Modern Art). Here he painted the first of his famous, iconic "Ned Kelly" series, reportedly with input from Sunday Reed. Nolan also conducted an open affair with Sunday Reed at this time although he married John Reed's sister, Cynthia in 1948, after Sunday refused to leave her husband. In 1978, Nolan married Mary née Boyd (1926- ), youngest daughter within the Boyd artistic family and previously married to John Perceval.
