Stylized blueprint portrait of Edward Weston

Edward Weston

1850 – 1936

Made precision electrical measurement an industrial commodity.

A British-American chemist and inventor, Weston developed the portable precision electrical instruments and the manganin resistance alloy that made calibrated current and voltage measurement an industrial reality in the 1890s.

The shunt-resistor tools here trace to his near-zero-temperature-coefficient alloy and the meters built around it. His standard cell defined the volt for decades.
