Albrecht von Haller

Haller revolutionised physiology. Boerhaave and Albinus taught him at Leiden, and Winsløw in Paris (he also studied mathematics with Bernoulli in Basel). Pringle was a fellow-student and close friend, corresponding for decades and instrumental in Haller’s opium addicition. Haller met Sloane and Cheselden in London, corresponded in Latin with Linnaeus for 30 years, and called Morgagni his master. Réaumur, Bodmer, Sulzer, Gottsched, Voltaire, Euler and Morgagni were among his extensive correspondents. Casanova visited him, describing him as a physical as well as mental colossus.
