  5. Há 2 dias · Electrical inventor Peter Cooper Hewitt built on the mid-19th century work of German physicist Julius Plücher and glassblower Heinrich Geissler. By passing an electric current through a glass tube containing tiny amounts of a gas, Plücker and Geissler found they could make light.

  6. 29 de jan. de 2019 · American Peter Cooper Hewitt (1861-1921) patented (U.S. patent 889,692) the first mercury vapor lamp in 1901. The low-pressure mercury arc lamp of Peter Cooper Hewitt is the very first prototype of today's modern fluorescent lights. A fluorescent light is a type of electric lamp that excites mercury vapor to create luminescence.

  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.
