…The company was founded as Haloid Co. In 1950, the company acquired the patent for electrostatic imaging (xerography, patented in 1940) invented by Chester F. Carlson (1906-1968), and began selling the Xerox A in the same year. In 1958, the company changed its name to Haloid Xerox Inc., and in 1961 to its current name. … From [Electronic Photography]...plain paper copy) and photocopy. Chester F. Carlson (1906-68), an American patent attorney, began researching ways to make transcription more efficient by using machines. In 1938, he succeeded in obtaining a photographic image by applying a static charge to a layer of sulfur molten on a zinc plate by frictional charging, and developing this with ruthenium powder (a type of electroscopic powder). He invented the basic principle of modern electrophotography and obtained a patent (1940). Later, the American company Xerox improved on this method by using amorphous selenium instead of sulfur and corona discharge instead of frictional charging, and in 1950, it was commercialized under the name Xerox. *Some of the terminology that mentions "Carlson, CF" is listed below.
