Lyttelton Stewart Forbes Winslow (January 31, 1844 - June 8, 1913) was an English psychiatrist famous for his involvement in the Jack the Ripper and Georgina Weldon cases during the late Victorian era. He was brought up in lunatic asylums owned by his father. He spent his medical career in an attempt to persuade the courts that crime and alcoholism were the result of mental instability. He managed his father's asylums after his death, but these were removed from his control following a family feud, so he turned his attention to solving crimes by using the deductive and reasoning methods of Arthur Conan Doyle's Sherlock Holmes. In 1874 he changed his surname to Forbes-Winslow. In 1888, with a little manipulation of the evidence, Winslow came to believe he knew the identity of Jack the Ripper, and believed that if he was given a team of six Police Constables he could catch the murderer. He founded the British Hospital for Mental Disorders in London, and was a lecturer on insanity at Charing Cross Hospital and was a physician to the West End Hospital and the North London Hospital for Consumption. He of a heart attack aged 69 in 1913.
