Cecil John Weeks, a nephew by marriage of General Leather Goods owner R.H. Cameron, worked with Cameron, who had founded the company in 1905. Jack Cooper, who also worked with GLG, joined Weeks in purchasing the company in 1949. The company was re-styled as Cooper Weeks. On June 15, 1971, the company was renamed Cooper of Canada, when Cecil Weeks sold out to Jack Cooper.
Innovation
Prior to Cooper and Weeks's purchase, the company had made ski and snowshoe harness sets. With the Great Depression impacting sales, they switched focus to economy-priced protective ice hockey shin guards and gloves. Frank Selke, manager of the Montreal Canadiens in the 1950s and early 1960s, worked with Cooper to decrease the weight and improve the durability and safety of hockey equipment. In 1969, the company introduced the plastic hockey stick replacement blade widely used in road hockey. Cooper employees and customers worked closely together to develop innovations like goaltenders' throat protection and professional grade lacrosse equipment. In the 1970s, when few professional athletes were paid to endorse equipment, Dave Dryden, brother of Ken Dryden, assisted the company in their Custom Pro Shop, sharing his latest thoughts on how to improve goaltenders' protective gear.
Some Cooper products met with limited consumer acceptance. A hockey pant and girdle called Cooperalls, Cooper shin pads, and the Cooper XL7 helmet have been named by critics among the worst hockey products of all time. They were designed by Steve Copeland and Len Clement of Cooper Design Group. Though used in the National Hockey League, the Cooper XL7 helmet met with particular criticism as being unsafe because of a plastic clip that could break upon face checking or puck impacts, detaching the faceguard.
Dissolution
Canstar Sports Inc., the parent company of hockey product manufacturer Bauer Hockey, acquired the hockey division of Cooper in 1990, and was itself acquired by Nike five years later. Former Cooper lead staff purchased the baseball bat manufacturing division in spring 1999 to form KR3. Jack Cooper was elected to the U.S. National Sporting Goods Association's Sporting Goods Industry Hall of Fame in 1979 and the Canadian Business Hall of Fame in 1989. As of 2008, the Cooper branding is applied to budget-line volleyballs and basketballs sold at discount stores. In Ireland, the Cooper brand is used for GAA equipment since Cooper ice hockey helmets made their way into hurling during the 1960s. By now, Cooper is "seen as the market leader" of hurling equipment in Ireland.
