Biography
He was born at Zeulenroda, in Upper Saxony, on 17 February 1756. His parents were the physician Johann Samuel Ackermann (1705-1762) and the Eva Rosine Oberreuther (1722-1776), the daughter of the tanning master Paul Steinmüller. Attending the University of Jena at only fifteen years old, Johann found a teacher in Ernst Gottfried Baldinger. The two relocated to Göttingen where he studied, apart from medicine, the classical sciences, as a student of Christian Gottlob Heyne. Ackermann was promoted in 1775 to private lecturer at the medical faculty of Halle, Saxony-Anhalt, Halle, where he lived for two years. Afterwards, he returned to Zeulenroda to practice medicine and physics. In 1786, he followed a call to Altdorf bei Nürnberg, Altdorf, where he was appointed professor of chemistry. In 1794 he accepted a position as chair of applied medicine and - at the same time - a position as the head of the local hospital for the poor. He died at the age of 45 from tuberculosis. The main focus of Ackermann's scientific works lies in his historical studies of the medical sciences during the Middle Ages. He collected several rare medical writings and translated foreign publications into German. He wrote ''Institutiones Historiae Medicinae'' (Nuremberg, 1792) and ''Institutiones Therapiae Generalis'' (Nuremberg and Altdorf, 1784-1795).Publications
