John Hopkinson
John Hopkinson, FRS, (27 July 1849 – 27 August 1898) was a British physicist, electrical engineer, Fellow of the Royal Society and President of the IEE (now the IET) twice in 1890 and 1896. He invented the three-wire (three-phase) system for the distribution of electrical power, for which he was granted a patent in 1882. He also worked in many areas of electromagnetism and electrostatics, and in 1890 was appointed professor of electrical engineering at King's College London, where he was also director of the Siemens Laboratory.
Hopkinson's law, the magnetic counterpart to Ohm's law, is named after him.

Famous quotes containing the word john:
“I do not wish to see John ever again,—I mean him who is dead,—but that other, whom only he would have wished to see, or to be, of whom he was the imperfect representative. For we are not what we are, nor do we treat or esteem each other for such, but for what we are capable of being.”
—Henry David Thoreau (1817–1862)
