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.
He was the doctoral advisor of Georg Gottlob Richter. In 1680, he became a member of Leopoldina.
