From Today in Science History:
Hermann Boerhaave, born 31 Dec 1668; died 23 Sep 1738
Dutch physician and professor of medicine who was the first great clinical, or “bedside,” teacher. To combine practice with theory, Boerhaave founded a hospital in which he gave clinical instruction to his pupils, thus introducing the clinical method into medical education. In 1718 he became professor of chemistry, and in 1724 he published Elementa Chemiae (Elements of Chemistry), a work that did much to make the science of chemistry clear and intelligible. He also made contributions in the field of botany.
