Hermann Conring, a German philosopher and author, born at Norden, East Friesland, Nov. 9,1606, died at Helmstedt, Dec. 12, 1681. He was the son of a clergyman, studied at Leyden, and was professor of philosophy, medicine, jurisprudence, and political science at Helmstedt, privy councillor to the duke of Brunswick, adviser of the emperor of Germany, and author of more than 100 works on German history and jurisprudence, and on scientific and theological subjects. Queen Christina of Sweden in vain sought to attach him permanently to her service. The duke of Brunswick and the kings of Sweden and Denmark conferred titles on him, and Louis XIV. granted him a pension. He encouraged the study of chemistry and pharmacy, and was one of the first to teach Harvey's doctrine of the circulation of the blood. A complete edition of his writings, with a biography, was published by Gobel (6 vols., Brunswick, 1730). - His daughter Elisa Sophie, baroness von Reichenbach, was distinguished as a poet; she died April 11, 1718.
