Biography
Deprez was born in Aillant-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

at the occasion of the Exposition of Electricity in the Glaspalast organised by Oskar von Miller. There he transmitted 1.5 kW at 2 kV over a distance of 35 miles.
Deprez conducted experiments in La Chapelle, Grenoble, Vizille, Paris, and Creil. He eventually attained transmission over thirty-five miles for industrial purposes. In 1889, Rene Thury continued his approach of arranging generators in series, eventually developing commercial systems delivering 20 megawatts at 125 kV over 230 kilometers.
