Birth of Samuel Haughton, Scientist, Mathematician & Doctor

samuel-haughtonSamuel Haughton, scientist, mathematician, and doctor, is born in Carlow, County Carlow on December 21, 1821. He is “famous” for calculating the drop required to kill a hanged man instantly.

Haughton is the son of James Haughton. His father, the son of a Quaker, but himself a Unitarian, is an active philanthropist, a strong supporter of Father Theobald Mathew, a vegetarian, and an anti-slavery worker and writer.

Haughton has a distinguished career at Trinity College, Dublin and in 1844 he is elected a fellow. Working on mathematical models under James MacCullagh, he is awarded in 1848 the Cunningham Medal by the Royal Irish Academy. In 1847 he has his ordination to the priesthood but he is not someone who preaches. He is appointed as professor of geology at Trinity College in 1851 and holds the position for thirty years. He begins to study medicine in 1859. He earns his MD degree in 1862 from the University of Dublin.

Haughton becomes registrar of the Medical School. He focuses on improving the status of the school and representing the university on the General Medical Council from 1878 to 1896. In 1858 he is elected fellow of the Royal Society. He gains honorary degrees from Oxford, Cambridge and Edinburgh. At Trinity College Dublin he moves the first-ever motion at the Academic Council to admit women to the University on March 10, 1880. Through his work as Professor of Geology and his involvement with the Royal Zoological Society, he has witnessed the enthusiasm and contribution of women in the natural sciences. Although thwarted by opponents on the Council he continues to campaign for the admission of women to TCD until his death in 1897. It is 1902 before his motion is finally passed, five years after his death.

In 1866, Haughton develops the original equations for hanging as a humane method of execution, whereby the neck is broken at the time of the drop, so that the condemned person does not slowly strangle to death. “On hanging considered from a Mechanical and Physiological point of view” is published in the London, Edinburgh, and Dublin Philosophical Magazine and Journal of Science, Vol. 32 No. 213 (July 1866), calling for a drop energy of 2,240 ft-lbs. From 1886 to 1888, he serves as a member of the Capital Sentences Committee, the report of which suggests an Official Table of Drops based on 1,260 ft-lbs of energy.

Haughton writes papers on many subjects for journals in London and Dublin. His topics include the laws of equilibrium, the motion of solid and fluid bodies, sun-heat, radiation, climates and tides. His papers cover the granites of Leinster and Donegal and the cleavage and joint-planes of the Old Red Sandstone of Waterford.

Haughton is president of the Royal Irish Academy from 1886 to 1891, and secretary of the Royal Zoological Society of Ireland for twenty years. In 1880 he gives the Croonian Lecture on animal mechanics to the Royal Society.

Haughton is also involved in the Dublin and Kingstown Railway company, in which he looks after the building of the first locomotives. It is the first railway company in the world to build its own locomotives.

Samuel Haughton dies on October 31, 1897 and is buried in the Church of the Holy Cross Cemetery in Killeshin, County Laois.

Birth of Sir Hans Sloane, Physician & Naturalist

Generated by IIPImageSir Hans Sloane, Irish physician and naturalist whose collection of books, manuscripts, and curiosities form the basis for the British Museum in London, is born on April 16, 1660 in Killyleagh, County Down in what is now Northern Ireland.

As a child Sloane possesses a strong curiosity of nature, and he develops a particular interest in plants. After studying medicine in London, he travels in France, taking an M.D. degree at the University of Orange in 1683. In 1685 he returns to London and is elected a fellow of the Royal Society. He proceeds to practice medicine as an assistant to British physician Thomas Sydenham. He is made a fellow of the Royal College of Physicians in 1687. That same year he accepts an opportunity to visit Jamaica, traveling as personal physician to the Christopher Monck, 2nd Duke of Albermarle, who had been appointed to govern the island.

The journey to Jamaica provides Sloane with the chance to pursue his interest in the natural sciences. During the 15 months of his travels, he visits multiple islands in the West Indies, including Saint Kitts, Nevis, and Barbados. He ultimately collects specimens of about 800 plants. He also records information on and collects specimens of various fish, mollusks, and insects, and he observes the local peoples and contemplates the natural phenomena of the area. His observations and the specimens he collects during the voyage lay the foundation for his later contributions to botany and zoology and for his role in the formation of the British Museum. He returns to England in 1689, his trip having been cut short by Monck’s death. His collection of plants from the West Indies is one of the first from that region to reach England.

Sloane’s trip to Jamaica also leads to his invention of a milk chocolate beverage. While on the island, he encounters a local drink made from a cacao plant. The beverage apparently makes him nauseous. To avoid this, he decides to mix the cacao material with milk. He finds this concoction to be not only more tolerable but also tasty and healthy. Shortly after his return to England, his milk-based concoction is sold by apothecaries as a medicinal product. His recipe later forms the basis for a milk chocolate product manufactured by Cadbury.

In 1696 Sloane publishes in Latin an elaborate catalogue, Catalogus Plantarum Quae in Insula Jamaica, on the plants he collected in Jamaica. He later publishes Natural History of Jamaica (2 Vol., 1707 and 1725), a comprehensive account of his studies of the natural phenomena of the island country.

Sloane also makes important contributions to medicine. He is physician to Queen Anne, King George I, and King George II. He is created a baronet in 1716, becoming the first medical practitioner to receive a hereditary title. He is relatively progressive as a physician, and, while serving George I, he adopts the practice of inoculation against smallpox for members of the royal family. In 1719 he is elected president of the Royal College of Physicians, a post he serves until 1735. In 1727 he becomes president of the Royal Society, succeeding physicist and mathematician Sir Isaac Newton. He holds the position until 1741. He earns a reputation as a specialist in eye diseases, and he eventually publishes Account of a Medicine for Soreness, Weakness and Other Distempers of the Eyes (1745).

Sloane is also known as an avid collector, and he benefits greatly from the acquisition of the cabinets of other collectors, including amateur scientist William Charleton and English apothecary and botanist James Petiver. When he retires from active work in 1741, his library and cabinet of curiosities has grown to be of unique value, and on his death he bequeaths his collection to the nation, on condition that parliament pay his executors £20,000. The bequest is accepted and goes to form the collection opened to the public as the British Museum in 1759.

Sloane has no son that survives beyond infancy, and the baronetcy becomes extinct upon his death in London on January 11, 1753.
