Walter Richard Sickert (31 May 1860 – 22 January 1942) was a German-born EnglishImpressionistpainter and a member of the Camden Town Group. Sickert was a cosmopolitan and eccentric who often favoured ordinary people and urban scenes as his subjects, but whose oeuvre also included portraits of well known personalities and friends, as well as images derived from press photographs. He is considered a prominent figure in the transition from Impressionism to modernism, and an important influence on distinctively British styles of avant-garde art in the 20th century.
Walter Sickert had been tangentially implicated in the Ripper crimes as early as the 1970s, with the release of the now infamous “Royal Conspiracy” theory. But it wasn’t until the early 1990s, with the release of Jean Overton Fuller’s Sickert and the Ripper Crimes, that the peculiar artist became a Ripper suspect in his own right. More recently, Patricia Cornwell has claimed to have found DNA evidence linking Sickert to at least one “Ripper letter”.
