1942 Electrophotography Patent Print, Electrophotography Invention Poster, Xerography Patent Poster Print, First Photo copier patent

1942 Electrophotography Patent designed by Chester Carlson. The patent was issued by the United States Patent Office on October 6, 1942.
History:
Chester Carlson (USA) invented the first photocopying machine and the technology to do so in 1938.
Carlson’s technology was turned away by many of the large corporations of the time including GE and IBM. However, Carlson continued developing his process until 1947, when a company called Haloid (a photographic paper company) sought a license to develop a market around his technology.
It was decided around this time that the phrase ‘electro photography’ was too complex, so, after consultation with a linguist, they chose the word ‘Xerography,’ which means ‘dry writing’ in Greek.
Haloid called the new devices Xerox machines, which was trademarked in 1948.
The company then changing its name to Xerox Corporation in 1961 which led to the creation of the verb ‘Xeroxing.’
