Sir Hans Sloane

Portrait of Sir Hans Sloane

Sir Hans Sloane (1660 – 1753) was born in Killyleagh, Ireland in relatively modest circumstances. Inspired by a childhood interest in natural history, he studied medicine in London and France. It was said of him by William Stukeley, the antiquary, that he was "an instance of the great power of industry which can advance a man to a considerable height in the world's esteem with moderate parts & learning..."

His career as a collector really began when in 1687, as personal physician, he accompanied the new Governor, the Duke of Albermarle, to Jamaica. He collected some 800 species of plants and other live specimens to bring back to London. An account of his travels was published in 1707 and 1725.

On his return to London in 1689 Sloane set up a successful medical practice at his home in No. 3 Bloomsbury Place - coincidentally just along the street from the present Museum building. He had a good bedside manner and accumulated wealthy and aristocratic patients, among them Queen Anne and Kings George I and II, but also participated in charitable work.

An innovative doctor, Sloane promoted inoculation against smallpox, the use of quinine (a treatment for malaria) and the health-giving properties of drinking chocolate mixed with milk. He became President of the College of Physicians in 1719 and in 1727 succeeded Sir Isaac Newton as President of the Royal Society.

In 1695 he married Elizabeth Langley, widow of Fulk Rose of Jamaica. They had two surviving daughters, Sarah who married George Stanley of Paultons, Hampshire and Elizabeth who became Lady Cadogan. He was created a Baronet in 1716.

He absorbed complete collections made by others, among them William Charlton (Courten) (1642-1702) and James Petiver (d.1718) and also received objects from friends and patients. One wit called him "the foremost toyman of his time". As a result his collection outgrew the house at No. 3 Bloomsbury Place and he purchased No. 4 as well.

In 1742 he moved with his collections to a manor house in Chelsea. His time there is still commemorated by such place names as 'Sloane Square' and 'Hans Crescent'.

Sloane died at the age of 93 in 1753 and was buried at Chelsea Old Church. His collection then amounted to more than 71,000 objects. Chiefly natural history specimens, the collection also included 1,125 "things relating to the customs of ancient times or antiquities" and 23,000 coins and medals. There were also 50,000 books, prints and manuscripts, together with a herbarium (a collection of dried plants).

A group of Trustees was appointed under the terms of his will to oversee the distribution of the collection which was left to King George II for the nation. Parliament intervened and Sloane's collection was acquired on payment of £20,000 to his two daughters and became the foundation of the British Museum.
