A great physician, born near Leyden, and son of a pastor; ultimately professor of Medicine and Botany there, as well as of Chemistry; chairs of which he filled and adorned with the greatest distinction; his reputation spread over Europe, and even as far as China—a letter from which bore the simple address, "To M. Boerhaave, Europe," and found him; his system was adopted by the profession, and patients from far and wide came to consult him—among others, Pope Benedict VIII. and Peter the Great; his character was as noble as his abilities were great; his principal works were "Institutiones Medicae," "Aphorismi de Cognoscendis et Curandis Morbis," "Libellus de Materia Medica," and "Institutiones Chemicae" (1668-1738).
