In 1905, Mogridge created the first crude protective head gear and was granted patent No. 780899 for a "head protector." This first attempt at a batting helmet was said to look like an "inflatable boxing glove that wrapped around the hitters head." Roger Bresnahan, Hall of Fame catcher who was injured after being struck in the head with a pitch, developed a leather batting helmet in 1908 which he began using. The helmets were not so much helmets as they were protective earmuffs. They did not protect the actual head of the batter but rather protected the ear and temple region. He also developed an aluminum protector for the back of the head that was covered in fake hair, but it is not known if it was ever used in the field.
