ILLIAM HEY, known for Hey's ligament, Hey's saw, and Hey's internal W derangement of the knee, was born in England in 1736. He was apprenticed to a Mr. Dawson, surgeon and apothecary of Leeds, and later became a pupil of William Bromfield, a surgeon at St. George's Hospital in London. After study in London, H e y returned to Leeds and devoted his energies to surgery. In 1767 he was instrumental in founding the Leeds General Infirmary, which ill recent years was increased in fame by Berkeley Moynihan. In this hospital H e y was the spirit of a surgical era for forty-five years. In 1764 Hey described infantile hernia. His greatest triumph for modern surgery was a description of internal derangenlent of the knee joint, the first condition of which he observed in 1782. H e y published in 1803 his "Practical Observations in Surgery," which is a mine of information for orthopedic surgeons. William H e y was in the same period of a galaxy of such British and Scottish surgeons as John and Charles Bell, Astley Cooper, Abernethy, Brodie, and Lawrence. William Hey, who died in 1819, was noted as a provincial surgeon. In the United Kingdom or America this should not denote narrowness of view, thought, or interest, especially when a marl of Hey's stature leaves a surgical heritage for the world.
