Just read my GenTips for May 19 and saw your notice. Several weeks ago I posted a two part writing about the Western Pennsylvania Hospital and the first medical school recognized in the 'Colonies' US. There were several methods by which a man became a doctor---by just practicing, by apprenticeship, and by school either here or overseas. If you contact the Antiquity Center, West Penn Hospital, 4815 Liberty AV, Pittsburgh PA 15224 with your questions, I am sure they will either be able to answer your questions or advise what booklets hold the information.
