one of the most learned men of his age, the son of a Lutheran minister in Denmark, was born in 1626. He applied himself to physic in the university of Copenhagen, and began to practise during a most terrible plague that made great havoc in that city. He travelled: but before his departure, in 1660, he was appointed professor in poetry, botany, and chemistry; and at his return discharged his duties with great assiduity, of which the works he published afford full proof. He was raised to the office of counsellor in the supreme council of justice, in 1686; to that of counsellor of the royal chancery, in 1689; and died of the operation for the stone, in 1690. He published, 1. Lingua pharmacopoeorum. 2. Dissertations de poeticiis Graecis et Latinis. 3. De ortu et progressi chemiae; and several other works.
