Samuel Haughton (21 December 1821 – 31 October 1897) was an Irish clergyman, medical doctor, and scientific writer. Biography The scientist Samuel Haughton was born in Carlow, the son of another Samuel Haughton (1786-1874) and grandson (by his second wife Jane Boake) of the three-times-married Samuel Pearson Haughton (1748-1828), a Quaker. Samuel Pearson Haughton was also father, by his third wife Mary Pim, of James "Vegetable" Haughton (1795–1873), a Unitarian, an active philanthropist, a strong supporter of Father Theobald Mathew, a vegetarian, and an anti-slavery worker and writer. The scientist Samuel Haughton had a distinguished career in Trinity College, Dublin and in 1844 he was elected a fellow. Working on mathematical models under James MacCullagh, he was awarded in 1848 the Cunningham Medal by the Royal Irish Academy. In 1847 he had his ordination to the priesthood but he was not someone who preached. He was appointed as professor of geology in Trinity College in 1851. He held the position for thirty years. Haughton began to study medicine in 1859. He earned his MD degree in 1862 from the University of Dublin. Haughton became registrar of the Medical School. He focused on improving the status of the school and representing the university on the General Medical Council from 1878 to 1896. In 1858 he was elected fellow of the Royal Society,. He gained honorary degrees from Oxford, Cambridge and Edinburgh. In Trinity College Dublin he moved the first-ever motion at the Academic Council to admit women to the University on 10 March 1880. He proposed that 'In the opinion of the Council, the time has come when the Degrees in Arts of the University should be opened to women, by examination, on the same terms as men' (Thomson, 2004). Haughton, through his work as Professor of Geology, and his involvement with the Royal Zoological Society had witnessed the enthusiasm and contribution of women in the natural sciences. Although thwarted by opponents on the Council he continued to campaign for the admission of women to TCD until his death in 1897. It was 1902 before his motion was finally passed, 5 years after his death. In 1866, Haughton developed the original equations for hanging as a humane method of execution, whereby the neck was broken at the time of the drop, so that the condemned person did not slowly strangle to death.
