Anna Kingsford, (16 September 1846 - 22 February 1888), was anti-vivisection, vegetarian and women's rights campaigner. She was one of the first English women to obtain a degree in medicine, and the only medical student at the time to graduate without having experimented on a single animal. She pursued her degree in Paris, graduating in 1880 after six years of study, so that she could continue her animal advocacy from a position of authority. This present work for was published in 1881 and originally was wrote in French at the Facult' de M'decin of Paris as a thesis on her degree.
