uric-acid-discovery
Assertion
Van Leeuwenhoek described tophus crystals in 1679; Scheele identified uric acid in a kidney stone in 1776; Wollaston found urate in a tophus in 1797; and Alfred Baring Garrod's 'thread test' measured uric acid in blood, leading him in 1859 to call deposited urate the cause of gouty inflammation.
Quote
In 1776 the chemical identity of uric acid was first established as a constituent of a renal calculus by the Swedish chemist Scheele, and the English chemist Woolaston demonstrated urate in a tophus from his own ear in 1797. Fifty years later, Sir Alfred Baring Garrod described his famous 'thread test' ... Garrod stated that, "the deposited urate of soda may be looked upon as the cause, and not the effect, of the gouty inflammation".
