History of the photocopier machine:
Chester Carlson, the inventor of photocopying, was originally a patent attorney, as well as a part-time researcher and inventor. Carlson used his kitchen for his "electrophotography" experiments, and, in 1938, he applied for a patent for the process. He made the first photocopy using a zinc plate covered with sulfur.
Inventor Chester Carlson used static electricity created with a handkerchief, light and dry powder to make the first copy on Oct. 22, 1938. The copier didn't get on to the market until 1959, more than 20 years later. When it did, the Xerox machine prompted a dramatic change in the workplace.
