Anton Ludwig Ernst Horn

Anton Ludwig Ernst Horn (24 August 1774 – 27 September 1848) was a German physician who was a native of Braunschweig.

For a short period of time he was a professor of medicine at the Universities of Wittenberg (1804) and Erlangen (1805), and in 1806 went to work at the medical hospital at the Charité in Berlin.

In the early 19th century, psychology as a scientific discipline was in its infancy, and barbaric, coercive methods were generally used to treat mental patients.

Horn believed that mental illness was largely due to physical suffering, and used an assortment of mechanical devices for therapeutic purposes.

In 1803 Horn published a practical textbook on pharmaceuticals titled Handbuch der praktischen Arzneimittellehre für Ärzte und Wundärzte.
