An Ulster-Scots born physician, scientist and avid collector, Sir Hans Sloane served as doctor to no less than three British monarchs during the 17^th and 18^th centuries and during his life amassed a vast collection of natural specimens and curiosities which after his death were used to form the core of the British Museum’s collection.

Born on 16^th April, 1660, at Killyleagh in County Down, Ireland, Sir Hans was the son of Alexander Sloane, a “receiver-general of taxes” who originally hailed from Scotland.

Even as a young man, he developed a keen interest in the natural sciences. Having suffered from some ill-health which, at the age of 16 is said to have kept him confined to a room for a year, in 1679, at the age of 19, he moved to London where he studied chemistry at the Apothecaries Hall and botany at the Chelsea Physic Garden – a period during which he befriended the botanist John Ray and chemist Robert Boyle.

Four years later, he travelled through France where he received his Doctorate of Physics. On his subsequent return to London in 1685, he was made a Fellow of the Royal Society and in 1687 a Fellow of the Royal College of Physicians.

Given the chance to travel to Jamaica as physician to the new Governor, Christopher, the 2nd Duke of Albemarle, he only spent 15 months there (the Governor died soon after arrival). But it was an important period during which not only did he document and collect a vast amount of flora and fauna (bringing some 800 specimens back to London), he also came up with the idea of drinking chocolate with milk after witnessing locals drinking the dark chocolate with water but finding the mix made him “nauseous” (back in England, his concoction was first sold as a medicine and was later manufactured as a drink by Cadburys).

Having returned to London in 1689, he published the information he had gathered in Jamaica, and in 1693 he become secretary to the Royal Society.

In 1695 he married a Jamaican sugar planter’s widow, Elizabeth Langley Rose (with whom he had several children but of whom only two daughters, Sarah and Elizabeth, survived) and, thanks in part to an ongoing association with the duke’s widow, was able to set up a fashionable medical practice at 3 Bloomsbury Place on the northern end of Bloomsbury Square.

The house, not far from where the British Museum now stands, become something of an attraction in its own right, filled with objects and specimens he had collected on his travels as well as those – in some cases complete collections – given to him by others including friends and patients (in fact, he had to purchase the property next door, number four, to find room for them all – this property is now marked with a Blue Plaque).

The composer Handel is said to have been among those who visited the property and there is a delightful tale that says Sir Hans was outraged when Handel placed a buttered scone on one of his rare books.

With his services as a physician highly prized, in 1696, he was appointed physician to Queen Anne, the first of the three monarchs he would serve. In 1712-13, with his collection still growing, he purchased the Manor of Chelsea to help house it (four acres of which were leased to the Chelsea Physic Garden, which had been founded in 1673 with the idea of providing a training ground for apprentice apothecaries, in perpetuity).

He subsequently moved his collection out to this property and his connection with Chelsea is still celebrated in place names such as name Sloane Square (not to mention Sloane Street, Sloane Gardens, Hans Street, Hans Crescent, Hans Road and Hans Place). There is also a statue of the bewigged man in Duke of York Square (pictured), not far from Sloane Square – this is a 2007 copy of 1737 original by John Rysbrack, another (older) copy of which can be found in the Chelsea Physic Garden.

Following Queen Anne’s death in 1714, in 1716 Sir Hans was appointed physician to her successor, King George I (he was also created a baronet the same year, becoming the first medical practitioner to receive a hereditary title).

Three years later, in 1719, he become president of the Royal College of Physicians, an office he held for 16 years, and in 1727, he was appointed physician to King George II. The same year he succeeded Isaac Newton as president of the Royal Society, an office which he held until 1741.

In 1742, Sir Hans retired to his property in Chelsea.

By the time of his death on 11^th January, 1753 at the ripe old age of 93, Sir Hans had collected more than 71,000 objects including books, manuscripts, drawings, coins and medals and plant specimens which he bequeathed to King George II in exchange for a payment of £20,000 to his executors.

Parliament agreed, following a lottery to raise the money, his collection went on to form the basis of the British Museum, first opened to the public in 1759 in Bloomsbury. It was also to form the basis of the museum’s later offshoot, the Natural History Museum at South Kensington.

Sir Hans was buried at Chelsea Old Church with his wife Elizabeth who died in 1724.
