Ernst Anton Nicolai

Ernst Anton Nicolai (7 September 1722, Sondershausen – 28 August 1802, Jena) was a German physician and chemist.

In 1745 he earned his medical doctorate from the University of Halle, where he was a disciple of Johann Heinrich Schulze and Friedrich Hoffmann. Soon afterwards, he obtained his habilitation in medicine, becoming an associate professor in 1748. At Halle, he gave lectures on theoretical subjects in the fields of pathology, physiology and pharmacology, later giving clinical lectures on diseases of the eye and childhood maladies.

In 1758 he was appointed professor of theoretical medicine at the University of Jena. During the following year, he became a professor of chemistry and clinical medicine at Jena, a position he held until his death in 1802. As a physician, he was a proponent of humoral pathology and the doctrine of vitalism. He was a follower of Leibniz' concept of monadism, reportedly seeking solutions to medical problems based on the philosophic viewpoints of Gottfried Leibniz.

He was the author of many works, being published in Latin and German. The following are his principal works that were written in the German language.
