Walter Richard Sickert (31 May 1860 – 22 January 1942) was a German-British painter and printmaker. He was a member of the Camden Town Group of Post-Impressionist artists in early 20th-century London. He was an important influence on British styles of avant-garde art in the mid- and late 20th century. His works were often about Jack the Ripper, which led some to believe he might have been the actual killer.
