Chester Carlson, American physicist and lawyer, invented Xerography (d. 1968)

Chester Floyd Carlson (February 8, 1906 – September 19, 1968) was an American physicist, inventor, and patent attorney born in Seattle, Washington.

He is best known for inventing electrophotography, the process performed today by millions of photocopiers worldwide. Carlson's process produced a dry copy, as contrasted with the wet copies then produced by the Photostat process. Carlson's process was renamed xerography, a term that means "dry writing."
