Walter Richard Sickert (31 May 1860 – 22 January 1942) was an English painter and printmaker who was a member of the Camden Town Group in London. He was an important influence on distinctively British styles of avant-garde art in the 20th century.
Sickert was a cosmopolitan and eccentric who often favoured ordinary people and urban scenes as his subjects. His oeuvre also included portraits of well-known personalities and images derived from press photographs. He is considered a prominent figure in the transition from Impressionism to Modernism.
Sickert was born in Munich, Germany on 31 May 1860, the eldest son of Oswald Sickert, a Danish-German artist, and his wife, Eleanor Louisa Henry, who was an illegitimate daughter of the British astronomer Richard Sheepshanks. In 1868, following the German annexation of Schleswig-Holstein, the family settled in Britain, where Oswald's work had been recommended by Freiherrin Rebecca von Kreusser to Ralph Nicholson Wornum, who was Keeper of the National Gallery at the time. The family obtained British nationality. The young Sickert was sent to University College School from 1870 to 1871, before transferring to King's College School, where he studied until the age of 18. Though he was the son and grandson of painters, he first sought a career as an actor; he appeared in small parts in Sir Henry Irving's company, before taking up the study of art in 1881. After less than a year's attendance at the Slade School, Sickert left to become a pupil and etching assistant to James Abbott McNeill Whistler. Sickert's earliest paintings were small tonal studies painted alla prima from nature after Whistler's example.
