Prince Albert Victor, Duke of Clarence and Avondale. Halftone print.

Prince Albert Victor, Duke of Clarence and Avondale, son of King Edward VII, heir to the throne. "His health had been undermined by heavy drinking, gout, and probably venereal disease; his dissipated lifestyle was unrelieved by any serious interests. He was said to be a regular patron of a homosexual brothel in Cleveland Street, central London, raided by the police in 1889, though his apparent involvement was kept a closely guarded secret for many years afterwards. He was also suspected, albeit on the flimsiest evidence, of being Jack the Ripper, responsible for murdering several East End prostitutes in 1888" (Oxford dictionary of national biography)
