Описание:

In October 1937 Chester Carlson, a patent attorney in New York, invented a process called electro photography. In 1938, this was renamed Xerography and the first known photocopy was the "10-22-38 Astoria". The Xerography copying process went on to become one of the most well-known inventions of the 20th century. Carlson received world acclaim and became extremely wealthy as his invention created a billion-dollar industry. It is estimated that Carlson gave away almost $100 million to charity and foundations before his death in 1968.
