Gideon Algernon Mantell MRCS FRS (3 February 1790 – 10 November 1852) was an English obstetrician, geologist and palaeontologist. His attempts to reconstruct the structure and life of ''Iguanodon'' began the scientific study of dinosaurs: in 1822 he was responsible for the discovery (and the eventual identification) of the first fossil teeth, and later much of the skeleton, of ''Iguanodon''. Mantell's work on the Cretaceous of southern England was also important. == Early life and medical career == Mantell was born in Lewes, Sussex as the fifth-born child of Thomas Mantell, a shoemaker,〔Cadbury, p. 38.〕 and Sarah Austen.〔Dean, p. 7.〕 He was raised in a small cottage in St. Mary's Lane with his two sisters and four brothers. As a youth, he showed a particular interest in the field of geology. He explored pits and quarries in the surrounding areas, discovering ammonites, shells of sea urchins, fish bones, coral, and worn-out remains of dead animals.〔Cadbury, p. 34.〕 The Mantell children could not study at local grammar schools because the elder Mantell was a follower of the Methodist church and the 12 free schools were reserved for children who had been brought up in the Anglican faith. As a result, Gideon was educated at a dame school in St. Mary's Lane, and learned basic reading and writing from an old woman. After the death of his teacher, Mantell was schooled by John Button, a philosophically radical Whig who shared similar political beliefs with Mantell's father.〔Cadbury, p. 36.〕 Mantell spent two years with Button, before being sent to his uncle, a Baptist minister, in Swindon, for a period of private study. Mantell returned to Lewes at age 15. With the help of a local Whig party leader, Mantell secured an apprenticeship with a local surgeon named James Moore.〔Cadbury, pp. 36–37.〕 He served as an apprentice to Moore in Lewes for a period of five years, in which he took care of Mantell's dining, lodging and medical issues. Mantell's early apprenticeship duties included cleaning vials, as well as separating and arranging drugs. Soon, he learned how to make pills and other pharmaceutical products. He delivered Moore's medicines, kept his accounts, wrote out bills and extracted teeth from his patients.〔Dean, p. 14.〕 On 11 July 1807, Thomas Mantell died at the age of 57.〔Dean, p. 13.〕 He left his son some money for his future studies.〔Cadbury, p. 37.〕 As his time in apprenticeship began to wind down, he began to anticipate his medical education. He began to teach himself human anatomy, and he ultimately detailed his new-found knowledge in a volume entitled ''The Anatomy of the Bones, and the Circulation of Blood'', which contained dozens of detailed drawings of fetal and adult skeletal features.〔 Soon, Mantell began his formal medical education in London. He received his diploma as a Member of the Royal College of Surgeons in 1811.〔Dean, pp. 16–17.〕 Four days later, he received a certificate from the Lying-in Charity for Married Women at Their Own Habitations that allowed him to act in midwifery duties. He returned to Lewes, and immediately formed a partnership with his former master, James Moore. In the wake of the cholera, typhoid and smallpox epidemics, Mantell found himself quite busy attending to more than 50 patients a day and delivering between 200 and 300 babies a year.〔Cadbury, p. 41.〕 As he later recalled, he would have to stay up for "six or seven nights in succession" due to his overwhelming doctoral duties. He was also able to increase his practice's profits from £250 to £750 a year.〔Dean, p. 17.〕 Although mainly occupied with running his busy country medical practice, he spent his little free time pursuing his passion, geology, often working into the early hours of the morning, identifying fossil specimens he found at the marl pits in Hamsey.〔Cadbury, p. 42.〕 In 1813, Mantell began to correspond with James Sowerby. Sowerby, a naturalist and illustrator who catalogued fossil shells, received from Mantell many fossilised specimens. In appreciation for the specimens Mantell had provided, Sowerby named one of the species ''Ammonites mantelli''.〔Dean, p. 28.〕 On 7 December, Mantell was elected as a fellow of the Linnean Society of London. Two years later, he published his first paper, on the characteristics of the fossils found in the Lewes area.〔Dean, p. 31.〕 In 1816, he married Mary Ann Woodhouse, the 20-year-old daughter of one of his former patients who had died three years earlier. Since she was not 21 and still technically a minor under English law, she had to obtain permission from her mother and a special licence to marry Mantell. After obtaining consent and the licence, she married Mantell on 4 May at St. Marylebone Church.〔 That year, he purchased his own medical practice and took up an appointment at the Royal Artillery Hospital, at Ringmer, Lewes. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gideon Mantell」の詳細全文を読む スポンサード リンク
