Ancient Greek philosopher Thales of Miletus described static electricity by rubbing fur on substances such as amber. 1600: English scientist William Gilbert coined the word electricus after careful experiments. He also explained the magnetism of Earth. 1660: German scientist Otto von Guericke invented a device that creates static electricity ...
The invention of the industrial generator in 1866 by Werner von Siemens – which did not need external magnetic power – made a large series of other inventions possible. In 1873, James Clerk Maxwell published a unified treatment of electricity and magnetism in A Treatise on Electricity and Magnetism which stimulated several theorists to ...
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 commutator.
The first half of the 700-page book is a history of the study of electricity. It is parted into ten periods, starting with early experiments "prior to those of Mr. Hawkesbee", finishing with variable experiments and discoveries made after Franklin's own experiments.

Voltages used for electric power transmission increased throughout the 20th century. [50] The first "high voltage" AC power station, rated 4-MW 10-kV 85-Hz, was put into service in 1889 by Sebastian Ziani de Ferranti at Deptford, London. [33] The first electric power transmission line in North America operated at 4000 V.
Safety lamps based on Clanny's improved design were used until the adoption of electric lamps. 1814: James Fox invents the modern planing machine, though Matthew Murray of Leeds and Richard Roberts of Manchester have also been credited at times with its invention. 1816: René Laennec invents the first Stethoscope.

Thomas E. Murray (October 21, 1860 – July 21, 1929) was an American inventor and businessman who developed electric power plants for New York City as well as many electrical devices which influenced life around the world, including the dimmer switch and screw-in fuse. It has been said that he "invented everything from the power plant up to ...
