  6. 22. März 2018 · More than a century ago, in 1902, American Engineer Peter Cooper Hewitt (1861-1921) derived the mercury-arc rectifier, enclosed in a glass bulb, from his mercury-vapor lamp of the previous year. He devised its use for feeding dc motors from alternating currents. As the first rectifier for power uses (two years before John Ambrose ...

  7. Peter Cooper Hewitt. 1861-1921. American electrical engineer who invented the mercury-vapor lamp. Between 1901-03 he made his mercury-vapor lamp commercially available as a reliable form of industrial lighting. His quartz-tube mercury lamp was widely used in the biological sciences.
