When was the  Anglo-Irish physician, naturalist and collector died who's niece recovered from spinal deformity due to Sarah "Crazy Sally" Mapp?
Sally Mapp Sarah "Crazy Sally" Mapp (died 1737) was an English lay bonesetter, who gained fame both by performing impressive bone-setting acts in Epsom and London, and by being a woman in a male-dominated profession. Bone-setting was a medical practice used to manipulate and fix musculoskeletal injuries using manual force. Mapp grew up in Wiltshire, England, and learned about the practice from her father, who was also a bone-setter. She frequently fixed horse racing injuries, but her most famous case was fixing the spinal deformity of Sir Hans Sloane's niece.
Kate Marsden Kate Marsden (13 May 1859 – 26 May 1931) was a British missionary, explorer, writer and nursing heroine. Supported by Queen Victoria and Empress Maria Fedorovna she investigated the care of leprosy. She set out on a journey from Moscow to Siberia to find a cure, creating a leper treatment centre in Siberia. She returned to England and inspired Bexhill Museum, but she was obliged to retire as a trustee. Marsden was dogged after her journey by homophobia, her finances were questioned as were her motives for her journey. Her accusers almost succeeded in making her sexuality the basis for an "Oscar Wilde"-type trial. She was however elected a fellow of the Royal Geographical Society. She has a large diamond named after her and is still remembered in Siberia, where a large memorial statue was erected at Sosnovka village in 2014.
