Title: Weston Dynamo, 19th Century
Caption: A dynamo is an electrical generator that produces direct current with the use of a commutator. Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current alternator, and the rotary converter. Edward Weston (May 9, 1850 - August 20, 1936) was an American chemist noted for his achievements in electroplating and his development of the electrochemical cell, named the Weston cell, for the voltage standard. Weston was a competitor of Thomas Edison in the early days of electricity generation and distribution. Realizing the need for a constant source of current, he developed an interest in power generation and invented several dynamos and generators.
