Chester Carlson
and a fellow scientist Otto Kornei, made
the first copying device on October 22, 1938. Yet it was not ready for use because the copy was made out of fungus spores.
Carlson had a lot of
trouble finding a company to sponsor him for further research.
Large companies such as Kodak, IBM, General Electric, RCA and more turned
him down. Finally a non profit organization Battelle Memorial
Institute provided him the funding to help him finish his research. As
soon as the researchers made a dry ink, (toner) the process was complete.
They hired a small photography manufacturer Haloid to help make the
copiers. Ten years after Carlson's first copying device Battelle and Haloid showed the world
the newest, easiest way to make copies.
Haloid changed it's name to Xerography getting it from the Greek words xeros for dry and graphos for writing. It is estimated, worldwide 3,000,000,000 copies are made everyday! |
