TORONTO—David Marsh, until recently the president and owner of Sydney R. Stone, passed away suddenly yesterday of a heart attack, PrintCan has learned. He was 60. He is survived by his wife Dorothy, five children and 6 grandchildren.

Marsh emigrated to Canada from England in 1975, and worked at various companies, including Computerized Cutters for several years, before buying Sydney R. Stone in 1989. He sold that company late last year.
