The Xerox 914 was the first successful commercial plain paper copier. Introduced in 1959 by the Haloid/Xerox company. It revolutionized the document-copying industry. The culmination of inventor Chester Carlson's work on the xerographic process, the 914 was fast and economical. The copier was introduced to the public on September 16, 1959, in a demonstration at the Sherry-Netherland Hotel in New York, shown on live television. Background Xerography, a process of producing images using electricity, was invented in 1938 by physicist-lawyer Chester Floyd "Chet" Carlson (1906–1968), and an engineering friend, Otto Kornei. Carlson entered into a research agreement with the Battelle Memorial Institute in 1944, when he and Kornei produced the first operable copy machine. He sold his rights in 1947 to the Haloid Company, a wet-chemical photopaper manufacturer, founded in 1906 in Rochester, New York. Haloid introduced the first commercial xerographic copier, the Xerox Model A, in 1949. The company had, the previous year, announced the refined development of xerography in collaboration with Battelle Development Corporation, of Columbus, Ohio. Manually operated, it was also known as the Ox Box. An improved version, Camera #1, was introduced in 1950. Haloid was renamed Haloid Xerox in 1958, and, after the instant success of the 914, when the name Xerox soon became synonymous with "copy", would become the Xerox Corporation. In 1963, Xerox introduced the first desktop copier to make copies on plain paper, the 813. It was designed by Jim Balmer and William H. Armstrong of Armstrong-Balmer & Associates, and won a 1964 Certificate of Design Merit from the Industrial Designers Institute (IDI). Balmer had recently left Harley Earl, Inc., where he had been a designer since 1946, to co-establish Armstrong-Balmer & Associates in 1958. At Earl, Balmer had been involved in the Secretary copy machine designed for Thermofax and introduced by 3M in 1958, and Haloid Xerox had been impressed with the design, engaging Balmer to consult on the final design of the 914. A year later, in 1964, Balmer worked with Xerox to establish their first internal industrial design group. Among those first design employees were William Dalton and Robert Van Valkinburgh. Specifications and features The 914 model (so-called because it could copy originals up to 9 inches by 14 inches (229 mm × 356 mm) could make 100,000 copies per month (seven copies per minute). In 1985, the Smithsonian received a Xerox 914, number 517 off the assembly line.
