Charles F. Brush
Born: 17 March 1849
Died: 15 June 1929
Early Life and Education
Charles Francis Brush , an American pioneer in the commercial development of electricity, was born 17 March 1849, on his parents' farm, about 10 miles east of Cleveland. He developed an interest in science and electricity at an early age, building his first static electric machine at age 12. Brush's parents realized that Charles would benefit greatly from a good education and they made the financial sacrifice to send him to Cleveland's Central High School. It was there that Brush fulfilled his boyhood dream of constructing an arc light. He graduated from Central High in 1867 with honors. An uncle of Charles' from his mother's side of the family provided a loan which enabled him to continue his education at the University of Michigan, from where he graduated in June 1869 at the age of twenty.
After graduation Brush returned to Cleveland where he established himself as an analytical and consulting chemist. Around 1873 he became reacquainted with a boyhood friend, George Stockly, who was vice president and general manager of the Telegraph Supply Company of Cleveland. Brush related some of his early experimentation with electricity to Stockly and discussed his vision for the development of arc lighting. The lighting system would need an efficient means of generating electricity, which Brush proposed to do by using a dynamo. Stockly was very impressed with Brush and his ideas and agreed to financially support his effort to construct a small dynamo. Brush assembled his first dynamo in the summer of 1876 while "vacationing" at his parents' farm. He used a horse-drawn treadmill to power the dynamo and was able to generate electricity with his new machine. He returned to the Telegraph Supply Company later that summer to continue the development work. These early efforts resulted in U.S. Patent No. 189 997, "Improvement in Magneto-Electric Machines", issued April 24, 1877.
Brush Arc Lights Illuminate Cities
In order to keep pace with the rapidly increasing demand for Brush lighting systems, the Telegraph Supply Company of Cleveland underwent significant restructuring, giving birth to the Brush Electric Company in the summer of 1880.
Later Career and Recognition
In 1889 the company merged with competitor Thompson-Houston Electric Company. Only two years later, in 1891, the new formed company merged again, this time with the Edison General Electric Company, to form the General Electric Company still known by the same name today. These mergers marked Brush's exit from the emerging electrical industry. He sold his interest in Brush Electric and moved on to other fields of endeavor, never to return to the electric industry.
In 1913 he was awarded the AIEE Edison Medal "For meritorious achievements in invention and development of the series arc lighting system." He passed away on 15 June 1929.
