Roger Bresnahan

On Opening Day at the Polo Grounds against the Phillies in 1907, future Hall of Famer Roger Bresnahan became the first catcher to wear the full suit of armor, or "tools of ignorance" -- glove, mask, chest protector, and shin guards -- in a regular-season appearance. The crowd reacted with derision. Bresnahan ignored them. (NATIONAL BASEBALL HALL OF FAME LIBRARY, COOPERSTOWN, N.Y.)
