‎First printing of Hertz' doctoral dissertation on the electromagnetic induction in rotating conductors, a purely theoretical work that took him only three months to complete.""It was not a pioneering work but a thorough study of the problem that had been partially treated by many others, from Arago and Faraday to Emil Jochmann and Maxwell. He submitted the dissertation in January 1880 and took his doctoral examination the following month, earning a magna cum laude, a distinction rarely given at Berlin.""(DSB).‎
