It has been sometime since I have posted – recent changes in my life situation have left me somewhat pre-occupied. For now here is a link to a paper on Reinier de Graaf, the doctor who first introduced Leeuwenhoek to the Royal Society in London:
In the second half of the 17th century, a young Dutch physician and anatomist left a lasting legacy in medicine. Reinier (also spelled Regner and Regnier) de Graaf (1641–1673), in a short but extremely productive life, made remarkable contributions to medicine. He unraveled the mysteries of the human reproductive system, and his name remains irrevocably associated with the ovarian follicle.
De Graaf was born in Schoonhaven, Holland. After studying in Utrecht, Holland, De Graaf started at the famous Leiden University. As a student, De Graaf helped Johannes van Horne in the preparation of anatomical specimens. He became known for using a syringe to inject liquids and wax into blood vessels. At Leiden, he also studied under the legendary Franciscus Sylvius.
