when did they start wearing helmets in baseball
Batting helmet In 1905, Mogridge[1] 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."[2] 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.[1] 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.
Logos and uniforms of the Pittsburgh Steelers The Steelers are the only NFL team that puts its logo on only one side of the helmet (the right side). Longtime field and equipment manager Jack Hart was instructed to do this by Art Rooney as a test to see how the logo appeared on the gold helmets; however, its popularity led the team to leave it that way permanently.[6] Since then, several college football teams such as Michigan State have followed the Steelers approach at one point or another and had their logo on only one side of the helmet. At the end of the 1962 season, they switched to black helmets for the 1962 Playoff Bowl to make it stand out more, and adopted the black helmets full time from the 1963 season onward. In 1977, the Steelers switched facemask colors from gray to black.
