Notes: Biographical/historical: Chester F. Carlson 1906-1968, patent attorney and inventor of xerography, was the son of poor Swedish immigrants. Carlson graduated from the California Institute of Technology in 1930. One of Carlson's first jobs was with the patent firm of P. R. Mallory. One of the aspects of patents is that multiple copies of patents are often needed. Prior to the 1930s, before xerography, the process was costly and slow. Carlson, therefore, sought to develop a quick and inexpensive copying machine. Through extensive research, with many hours spent at the New York Public Library and with the assistance of a refugee physicist, Otto Kornei, he perfected the process. On October 22 1938, the first image read "10-22- Astoria". Carlson's invention did not sell at first, because of a lack of commercial interest. During the year 1944, the Battelle Memorial Institute of Columbus, Ohio agreed to market the process. In January 1947, the Haloid Corporation later the Xerox Co., made a licensing agreement with the Battelle Corporation. The first xerox machine was marketed in 1950; the royalties eventually made Carlson a multi-millionaire. Carlson was also known as a philanthropist. Carlson died in 1968; he was survived by his wife Dorrie Carlson and a daughter, Catherine.; Content: The Chester F. Carlson Papers contain the papers of Chester F.
