lyn47414

(London, Richard and John E. Taylor, 1837). No wrappers. Extracted fron "Scientific Memoirs, selected from The Transactions of Foreign Academies of Science and Learned Societies. Edited by Richard Taylor.", Vol. I. Pp. 503-531 and 1 large folded lithographed plate, showing "Jacobi's Electro-Motive Machine" with diagrams. With titlepage to volume 1. ¶ First apperance in English of Jacobi's description of his invention of the first real electric motor. The original pamphlet appeared in Potsdam in 1835, written in French. This first electric motor set a world record in performance that stood for four years and was improved in September 1838 only by Jacobi himself. It was not before 1839/40 when other developers worldwide managed to build motors of similar and later also of higher performance.

"In 1838 his motor drove a twenty-eight-foot boat carrying a dozen Russian officials on the Neva River at a speed of one and one-half miles per hour. His hopes of covering the Neva with a fleet of magnetic boats were doomed from the beginning, however, by the cost of battery-powered operation and by the fumes that such batteries emitted." (DSB).

In May 1834 Moritz Jacobi built the world's first real electric motor in Königsberg. There had been other rotating electromagnetic devices before but none of them developed a significant mechanical output power. The first rotating device was already created in 1822 by Peter Barlow (Barlow's wheel).
Jacobi's electric motor developed as much as 15 watt. This first electric motor set a world record in performance that stood for four years and was improved in September 1838 only by Jacobi himself. It was not before 1839/40 when other developers worldwide managed to build motors of similar and later also of higher performance.

In January 1834 he writes a letter to Poggendorf, editor of the Annalen der Physik und Chemie of his successes. He now turns to the construction of a real electric motor, which he completes in May 1834.

Moritz Hermann Jacobi (German-speaking Prussian, naturalized Russian) is born in Potsdam in 1801. He moves to Königsberg (then Prussia, now Russia) in the beginning of 1833 and starts with experiments on horseshoe-shaped electromagnets.
