|Jabberwocky||Fun facts about xerography!|| Xerography was invented by American physicist Chester F. Carlson (1906–1968) in 1938. After earning his physics degree from the California Institute of Technology in 1930, Carlson accepted a job working for the P.R. Mallory Company, an electronics business in New York. Working in the patent department, Carlson was frustrated by the difficulty of obtaining copies of patent drawings and specifications. He decided to use his time away from work to find a solution to the problem.
Focusing on the concept of electrostatics, Carlson spent four years before succeeding in production his first "dry-copy." The first successful copy was a notation of the date and location that read "10.-22.-38 Astoria." (Carlson lived in Astoria, Queens, New York at the time.) In 1940, Carlson obtained the first of many patents for his xerographic process. Wanting to find a company that would help him develop and market his idea, Carlson began showing his solution to many organizations. After more than twenty firms turned down his invention, Carlson finally reached an agreement in 1944 with the Battelle Memorial Institute, a nonprofit research organization. Three years later, the Haloid Company (later the Xerox Corporation) became a partner in the development of the xerography technology. Finally, after years of development, the first office copier—the Xerox 914—was introduced in 1959.
