Life
Coehn received his doctorate in 1888 with a thesis on electrolytic investigations . He was an employee of Walther Nernst in Göttingen and headed the photochemistry department, the underfunding of which he compensated with his own funds (he was wealthy). He dealt in particular with electrochemistry and photochemistry. Coehn's rule is named after him, according to which, in the case of static electricity, the positive charges generally arise in the substance with a higher dielectric constant . He also demonstrated that with static electricity, even close contact is sufficient for charge separation (and friction is not absolutely necessary). He worked for the handbook of physics .
After the handover of power to the National Socialists, Coehn was removed from university service for racist reasons.
