Johann Ludwig Hannemann (1640–1724) was a professor of medicine who famously opposed the idea of the circulation of the blood. He studied the chemistry of phosphorus, gold, and hematite; wrote articles on metallurgy, botany, theology, and various medical topics. He was an adherent of the views of the ancients and pre-Renaissance alchemists. He trained his medical students according to the schools of Galen, Hippocrates, and Aristotle.
He first studied theology before studying medicine.
In 1675, he became a Full Professor at the University of Kiel.
He was the doctoral advisor of Georg Gottlob Richter. In 1680, he became a member of Leopoldina.
