In the 1970s, Tunnicliffe led the development of a standard called GenCode for the publishing industry. He served as the first chair of the International Organization for Standardization committee that developed the first international standard for markup languages, ISO 8879.

Tunnicliffe was a member and former chairman of the Printing Industries of America, and held the rank of captain in the US Navy and Navy Reserves until 1982.^[1]
