The Origins of Electrical Measuring Instruments
|Edward Weston (1850 - 1936) was one of the most
significant persons in the history of electrical measuring instruments.
In the field of measurement, he developed three important components:
the Standard Cell, the Manganin resistor and the electrical indicating
instrument. The New Jersey Institute of Technology in Newark, NJ has
established an archive in honor of Edward Weston and his work.
Newark is located south of New York across the Hudson River. It was settled by Connecticut Puritans in 1666, and was one of the first areas to be urbanized in the United States, following Boston and New York on the East Coast. From the late-19th to early-20th century, Newark became a major hub for such prosperous industries as leather, chemical fertilizers, metals, jewels and electrical appliances.
A number of factories and laboratories run by well-known inventors and entrepreneurs were established in Newark. One example is Thomas Edison (1847 - 1931) who manufactured stock tickers and also built a large-scale laboratory in the suburb, West Orange. Newark is also known as the place where John Wesley Hyatt (1837 - 1920) invented the synthetic plastic resin "celluloid" that replaced the ivory used to make billiard balls.
Weston was both - an inventor and an entrepreneur. As an inventor, he acquired more than 200 patents from the time direct-current generators and arc lamps emerged. He also set up a number of companies, the most successful of which seemed to be the Weston Electrical Instrument Company.
