William Cheselden

William Cheselden (; 19 October 168810 April 1752) was an English surgeon and teacher of anatomy and surgery, who was influential in establishing surgery as a scientific medical profession. Via the medical missionary Benjamin Hobson, his work also helped revolutionize medical practices in China and Japan in the 19th century.

Life

Cheselden was born in Somerby, Leicestershire on 19 October 1688. He studied anatomy in London under William Cowper (1666–1709), and began lecturing anatomy in 1710. That same year, he was admitted to the London Company of Barber-Surgeons, passing the final examination on 29 January 1711.

He was elected as a Fellow of the Royal Society in 1712 and the following year saw the publishing of his Anatomy of the Human Body, which achieved great popularity becoming an essential study source for students, lasting through thirteen editions, Cheselden presented the celebrated case of a boy of thirteen who gained his sight after removal of the lenses rendered opaque by cataract from birth. Despite his youth, the boy encountered profound difficulties with the simplest visual perceptions. Described by Cheselden: When he first saw, he was so far from making any judgment of distances, that he thought all object whatever touched his eyes (as he expressed it) as what he felt did his skin, and thought no object so agreeable as those which were smooth and regular, though he could form no judgment of their shape, or guess what it was in any object that was pleasing to him: he knew not the shape of anything, nor any one thing from another, however different in shape or magnitude; but upon being told what things were, whose form he knew before from feeling, he would carefully observe, that he might know them again;

Philosopher George Berkeley claimed that his visual theories were “vindicated” by Cheselden's 1728 report on this congenital cataract patient. In 2021, the patient's name was published for the first time: Daniel Dolins. Berkeley knew the Dolins family, had numerous social links to Cheselden, including the poet Alexander Pope, and Princess Caroline, to whom Cheselden's patient was presented. The report misspelled Cheselden's name, used language typical of Berkeley, and may even have been ghost-written by Berkeley. Unfortunately, Dolins was never able to see well enough to read, and there is no evidence that the surgery improved Dolins' vision at any point prior to his death at age 30.

Works Cheselden is famous for the invention of the lateral lithotomy approach to removing bladder stones, which he first performed in 1727. The procedure had a short duration (minutes instead of hours) and a low mortality rate (approximately 50%). Cheselden had already developed in 1723 the suprapubic approach, which he published in A Treatise on the High Operation for the Stone. In France, his works were developed by Claude-Nicolas Le Cat.

He also effected a great advance in ophthalmic surgery by his operation, iridectomy, described in 1728, to treat certain forms of blindness by producing an artificial pupil. Cheselden also described the role of saliva in digestion. He attended Sir Isaac Newton in his last illness and was an intimate friend of Alexander Pope and of Sir Hans Sloane.
