Mr. Cady contributed many articles and reports for publication in AATCC proceedings.  His work in connection with Light Fastness is foremost as is his work on Print Pastes.  Dr. Olney reported that seventeen papers and reports were published.  He served on fourteen different committees and was Chairman of at least six.

He was invited to attend the small group of textile chemists that gathered at the Engineers Club in Boston August 21, 1921 to consider forming an association for textile chemists and colorists.  He organized the Rhode Island Section with 26 signatory members by November 18th, two weeks after the formation of the American Association of Textile Chemists and Colorists.
