8175 Boerhaave           Discovered 1991 Nov. 2 by E. W. Elst at the European Southern Observatory.
Named in memory of the Dutch physician and professor of medicine Hermann Boerhaave (1668-1738). He was a brilliant teacher of botany, medicine and chemistry at the University of Leiden, where students came from all parts of Europe to hear him. Baron d´Holbach and de Lamettrie studied with him. He is credited with founding the modern system of teaching medical students at the patient's bedside. He is the author of Institutiones Medicae and Aphorismi de Cognoscendis et Curandis Morbis, two textbooks widely used during and after his lifetime.
