Born Feb. 8: Chester Carlson
By Michael Baadke
Chester Carlson, the inventor who developed the technology that led to office copiers, was honored on a 21¢ stamp issued Oct. 21, 1988 (Scott 2180). The stamp is a Great Americans series definitive then paying the rate for postcards mailed to Canada.
Chester Floyd Carlson was born in Seattle, Wash., on Feb. 8, 1906. He earned a degree from the California Institute of Technology in 1930, and worked for P.R. Mallory and Co., a manufacturer of batteries and electronics.
Looking for a way to conveniently reproduce patent specifications, Carlson experimented with photoconductivity rather than photography, and in 1938 invented the technology that would be called “xerography,” from the Greek for “dry printing.”
Working with Battelle Development Corp. and the Haloid Co. (later renamed Xerox Corp.), Carlson’s efforts led to the development of xerographic equipment, offered commercially in 1950.
“Although Carlson is hardly a household name,” the Postal Service wrote in its Philatelic Release No. 68 in 1988, “the process he invented in 1938 is today embodied in an indispensable business tool used by millions of people around the world. But, though his invention has become one of the most profitable products of all time, to those who knew him, Carlson is remembered more for his determination, his kindness and his extraordinary generosity.”
Carlson’s invention brought him great wealth, and he donated $100 million to charity before his death in 1968.
Oct. 22, 1988, the 50th anniversary of Carlson’s invention of xerographic printing, was proclaimed as National Chester F. Carlson Recognition Day with a Congressional House Joint Resolution signed by President Ronald Reagan.
