The first one.......

Hi friends, do you know who invented the first xerox machine. If not, I am ready to explain it for you people. In 1937, the process called Xerography was invented by American law student Chester Carlson. Carlson had invented a copying process based on electrostatic energy. Xerography became commercially available in 1950 by the Xerox Corporation. Xerography comes from the Greek for "dry writing".Chester Carlson had been frustrated with the slow mimeograph machine and the cost of photography and that lead him to inventing a new way of copying. He invented an electrostatic process that reproduced words on a page in just minutes. Carlson had a hard time finding investors in his new invention. He was turned down by IBM and the U.S. Army Signal Corps, it took him eight years to find an investor, which was the Haloid Company later to become the Xerox Corporation. Thus the Xerox Corporation trademarked the name "Xerox" and has protected the name carefully. So if today xerox machine is not there, we would still depend on photography and printing. Thus xerography saved our money and time…..
