Under the London Company, the physicians and surgeons in Virginia had the same education, training, and met the same standards as their counterparts in England. This was, in part, because the Company had good reason to supply adequate medical service, and because the men sent were but Englishmen transplanted to America. Walter Russell, who came to Virginia in 1608 was a "Doctour of Physicke" and Lawrence Bohun, De la Warr's physician, had the same degree. Pott, who succeeded Bohun as physician-general of Virginia in 1621, came recommended as a Master of Arts well-practiced in surgery and physics. After the Company's charter was annulled, few physicians or surgeons with the advanced medical degrees came to Virginia. Some of the persons, however, who practiced medicine in Virginia without medical degrees had acquired skills and knowledge in Europe or England before coming to the New World. Patrick Napier who came to Virginia about 1655 as an indentured servant and subsequently had a large medical practice, probably learned his profession in England or on the Continent, as might have Francis Haddon, another who came under terms of indenture and who later, also, had a considerable medical practice. To these two examples of persons with training and experience acquired prior to their arrival in America might be added the similar experiences of John Williams and John Inman. Medical knowledge and practices brought over from England were cross-fertilized with the European even in the New World. While the majority of newcomers were Englishmen, French, German, and other European physicians and surgeons came to Virginia. These European medical men appear, in general, to have prospered in Virginia and were anxious to become naturalized "denizens to this country." George Hacke, born in Cologne, Germany, settled in Northampton County, Virginia, in 1653 and was known as a doctor and practitioner of medicine. He was typical of the European-trained medical man settling in Virginia in becoming naturalized and in leaving a considerable estate, including thousands of acres of land. Little is known of his medical activities and interests except that he was summoned to treat the victim of a duel and that he left a large library which probably included volumes on medicine. Paul Micou, a young French physician who seems to have acquired his education abroad, settled on the shores of the Rappahannock river, near a place afterward called Port Micou, during the last decade of the seventeenth century. Cultured and educated, he soon won prominence and wealth as a physician (and surgeon), attorney, and merchant. County records in Virginia make numerous references to suits brought by him for nonpayment of fees, suggesting an extensive practice.
