Sebaldus Jnstinus Brugmans, a Dutch physician and naturalist, born in Franeker, March 24, 1763, died in Ley den, July 22, 1819. The academies of Dijon, Bordeaux, and Berlin awarded prizes to several of his disquisitions on natural history and botany. Becoming professor of philosophy and physical sciences at Franeker, he promoted the study of natural history in the Netherlands, and founded a museum of comparative anatomy which became famous. King Louis Bonaparte attached him to his service, and being appointed professor of botany at Leyden, he also taught there other branches of natural history and chemistry and organized the sanitary institutions of Holland, of which he was made chief director. After the annexation of Holland to France, Napoleon made him rector of the university of Leyden, which he cleared of debt. He especially improved the condition of military hospitals, and it was mainly due to his efforts that relief for over 20,000 wounded soldiers was provided after the battle of Waterloo. In 1815 King William placed him at the head of the sanitary service of the army and navy, and sent him to France to demand the restitution of the collection of natural history which had been taken away during the French domination.

He was the chief editor of the Pharmacopoeia Batava, and published numerous writings on medical science and natural history.
