American electircal engineer, inventor and manufacturer noted for his electric instruments, especially his permanent-magnet movingcoil type of instrument introduced in 1888. He founded the Weston Electrical Instrument Company in Newark, NJ.

From Mitchell Charles Harrison, Prominent and progressive Americans: an encyclopædia of contemporaneous biography, (New York, 1904), Volume 2, 223-224:

"Before attaining his majority Mr. Weston came to the United States, arriving in New York in May, 1870. Here he promptly went to work in his chosen department of industry. His first engagement was in the employ of the American Nickel Plating Company, where he remained for three years as chemist and electrician. In December, 1873, he established a nickel-plating concern of his own, and conducted it successfully for two years.

Meantime he devoted much attention to the study of electrical engineering, especially of dynamo-electric machinery, with the result that in 1875 he organized a firm for the manufacture of such machines. This firm had a successful career for two years, and then, on July 10, 1877, was reorganized as the Weston Electric Light Company. In that new capacity it enjoyed greatly enlarged prosperity for a number of years. Consolidation of business enterprises was, however, then beginning to be the order of the day, and this company soon joined in the movement. In 1881 he formed a union with another company, the new corporation being known as the United States Electric Light Company of New York.

Mr. Weston has the distinction of having prepared the first copper-coated carbon pencils for use in electric arc-lights. This he did in 1873, and his invention is now in practically worldwide use. He is president and a director of the corporation publishing the well-known periodical "Electricity," and is a director of the Sixth Avenue Railroad Company in New York."
