The first goaltender to wear a mask in an organized ice hockey game was Elizabeth Graham of Queen’s University in 1927. The first National Hockey League (NHL) goalie to wear a mask full-time was Jacques Plante of the Montreal Canadiens; he wore a face-hugging fibreglass mask created by Bill Burchmore beginning in 1959. The construction and design of goalie masks gradually improved to include a caged section over the eyes and nose. This hybrid-style fibreglass mask was adapted for use in baseball by Toronto Blue Jays catcher Charlie O’Brien in 1996. However, concerns have arisen over the safety of goalie masks and goalie-style catcher masks, particularly their ability to protect against concussions.
