A new dry method of photography and printing by electrostatics was demonstrated by R. M. Schaffert and Joseph C. Wilson at the annual meeting of the Optical Society of America in Detroit. The process, called xerography, substitutes powders for ordinary developers and ink, and involves no chemical reaction. It was invented by Chester F. Carlson and developed by Battelle Memorial Institute, and the Haloid Company has arranged to use and license it.
