Moritz von Jacobi was a German-Russian electrical engineer and physicist who is usually credited with building, in May 1834, the first genuinely useful rotating electric motor, predating Thomas Davenport's independently developed and patented American motor by three years. Working at the Russian Academy of Sciences with the financial support of Tsar Nicholas I, Jacobi built a battery-powered electric boat that carried fourteen passengers against the current of the Neva River in 1839, discovered electrotyping (galvanoplastics) in 1838, and later formulated the maximum power transfer theorem that bears his name.

With the financial assistance of Tsar Nicholas I, Jacobi constructed in 1839 a 28-foot electric motor boat powered by battery cells. It carried 14 passengers on the Neva river against the current at three miles per hour. He had begun to study magnetic motors in 1834 and moved to Saint Petersburg in 1837 to research the use of electromagnetic forces for moving machines at the Russian Academy of Sciences. While studying the transfer of power from a battery to an electric motor he deduced the maximum power theorem.
