Emil Stöhrer and the development of electrical motor technology in the 1840s

After the discovery of the basic laws of electrophysics, many scientists, inventors, and mechanics ventured their work in this new field of physics. Among them was a Leipzig based mechanic Emil Stöhrer who is widely unknown today. However, in particular through a series of articles in prominent scientific journals, his work became known in the scientific community during his lifetime. This paper gives an introduction to his life and work in electrophysics.
