Marcel Deprez (12 December 1843 – 13 October 1918) was a Frenchelectrical engineer. He was born inAillant-sur-Milleron. He died inVincennes.
Deprez was born inAillant-sur-Milleron in rural France and attended the School of Mines in Paris. He was not able to complete the course; however, he must have made a good impression, as he was employed as a secretary to the director of the school,Charles Combes.[1]
AtCreil, from 1876 to 1886, Deprez conducted the first experiments to transmitelectrical power over long distances. At theInternational Exposition of Electricity, Paris, in 1881, Deprez undertook the task of presenting anelectricity distribution system based on the long-distance transmission ofdirect current. The first successful attempt took place in 1882 fromMiesbach toMunich at the occasion of the Exposition of Electricity in the Glaspalast organised byOskar von Miller. There he transmitted 1.5 kW at 2 kV over a distance of 35 miles.[2]
Deprez conducted experiments in La Chapelle, Grenoble, Vizille, Paris, and Creil. He eventually attainedtransmission over thirty-five miles for industrial purposes. In 1889,René Thury continued his approach of arranging generators in series, eventually developing commercial systems delivering 20 megawatts at 125 kV over 230 kilometers.[2]
