Hans Sloane

He had as a youth a taste for collecting objects of natural history and other curiosities. This led him to the study of medicine, which he went to London to pursue, directing his attention to botany, materia medica and pharmacy. His collecting propensities made him useful to John Ray and Robert Boyle.

After four years in London he travelled through France, spending some time at Paris and Montpellier, and taking his M.D. degree at the university of Orange[?] in 1683. He returned to London with a considerable collection of plants and other curiosities, of which the former were sent to Ray and utilized by him for his History of Plants.

Sloane was quickly elected into the Royal Society, and at the same time he attracted the notice of Thomas Sydenham[?], who gave him valuable introductions to practice. In 1687 he became fellow of the College of Physicians, and proceeded to Jamaica the same year as physician in the suite of the duke of Albemarle. The duke died soon after landing, and Sloane's visit lasted only fifteen months; but during that time he got together about 800 new species of plants, the island being virgin ground to the botanist. Of these he published an elaborate catalogue in Latin in 1696; and at a later date (1707-1725) he made the experiences of his visit the subject of two folio volumes. He became secretary to the Royal Society in 1693, and edited the Philosophical Transactions for twenty years.

His practice as a physician among the upper classes was large. In the pamphlets written concerning the sale by Dr William Cockburn[?] (1669-1739) of his secret remedy for dysentery and other fluxes, it was stated for the defence that Sloane himself did not disdain the same kind of professional conduct; and some colour is given to that charge by the fact that his only medical publication, an Account of a Medicine for Soreness, Weakness and other Distempers of the Eyes (London, 1745) was not given to the world until its author was in his eighty-fifth year and had retired from practice.

In 1716 Sloane was created a baronet, being the first medical practitioner to receive an hereditary title, and in 1719 he became president of the College of Physicians, holding the office sixteen years. In 1722 he was appointed physician-general to the army, and in 1727 first physician to George II. In 1727 also he succeeded Sir Isaac Newton in the presidential chair of the Royal Society; he retired from it at the age of eighty.

Sloane's memory survives more by his judicious investments than by anything that he contributed to the subject matter of natural science or even of his own profession. His purchase of the manor of Chelsea in 1712 has perpetuated his memory in the name of a "place," a street, and a square. His great stroke as a collector was to acquire (by bequest, conditional on paying of certain debts) in 1701 the cabinet of William Courten[?], who had made collecting the business of his life.

When Sloane retired from active work in 1741 his library and cabinet of curiosities, which he took with him from Bloomsbury to his house in Chelsea, had grown to be of unique value. On his death on January 11 1753 he bequeathed his books, manuscripts, prints, drawings, pictures, medals, coins, seals, cameos and other curiosities to the nation, on condition that parliament should my to his executors £20,000, which was a good deal less than he value of the collection.

The bequest was accepted on those terms by an act passed the same year, and the collection, together with George II's royal library, etc., was opened to the public at Bloomsbury as the British Museum in 1759. Among his other acts of munificence may be mentioned his gift to the Apothecaries' Company of the botanical or physic garden, which they had rented from the Chelsea estate since 1673.
