The magnet was made of 18 turns of bare copper wire (insulated wire had not yet been invented). [1] William Sturgeon (22 May 1783 – 4 December 1850) was an English physicist and inventor who made the first electromagnets, and invented the first practical electric motor.
But in 1914 when D. D. Sturgeon-founder of Sturgeon Electric-wanted to give his ill son some Christmas joy, he wrapped his pine trees with electric bulbs, which were dipped in red and green paint.
Sturgeon. Sturgeon (from Old English styrġa ultimately from Proto-Indo-European * str̥ (Hx)yón - [1]) is the common name for the 28 species of fish belonging to the family Acipenseridae. The earliest sturgeon fossils date to the Late Cretaceous, and are descended from other, earlier acipenseriform fish, which date back to the Early Jurassic ...
Electrical engineering is an engineering discipline concerned with the study, design, and application of equipment, devices, and systems which use electricity, electronics, and electromagnetism. It emerged as an identifiable occupation in the latter half of the 19th century after the commercialization of the electric telegraph, the telephone ...
William Sturgeon built an electric motor in 1832 and invented the commutator, a ring of metal-bristled brushes which allow the spinning armature to maintain contact with the electric current and changed the alternating current to a pulsating direct current. He also improved the voltaic battery and worked on the theory of thermoelectricity.
The Western Electric Company was an American electrical engineering and manufacturing company that operated from 1869 to 1996. A subsidiary of the AT&T Corporation for most of its lifespan, Western Electric was the primary manufacturer, supplier, and purchasing agent for all telephone equipment for the Bell System from 1881 until 1984, when the Bell System was dismantled.

1828, Ányos Jedlik. Hungarian, physicist and unsung father of the dynamo and electric motor; invented the first commutated rotary electromechanical machine with electromagnets. [3][5] He invented the commutator. In 1828 Jedlik demonstrated the first device to contain the three main components of practical DC motors: the stator, rotor and ...
