The company was founded by John Tate Riddell, who invented the removable cleat. Riddell specialized in cleats until 1939, when John Tate Riddell invented the plastic shell helmet. This was followed by the invention of the plastic suspension helmet in the early 1940s, which was used by the United States Military during the Second World War. Throughout the latter half of the 20th century, the company introduced new helmet technologies, such as facemasks in the 1950s, air-filled padding in the 1960s, and helmets with multiple inflation points in the 1990s. Following the success of helmets designed to reduce concussions in addition to skull injuries, Dan Arment was appointed president of Riddell in 2008. Arment previously worked as executive vice-president and general manager of mass-market business. Riddell is owned by private equity firm
Fenway Partners. Fenway acquired the company in 2003 from
Lincolnshire Management. In 2008, Riddell sued competitor
Schutt Sports. Two years later, Schutt filed a lawsuit, also for patent-infringement, against Riddell. Riddell won, leading to Schutt filing for bankruptcy. == Products ==
