Helmets were made mandatory in 1971 but were in use by many players as far back as the 1940s. Hall of Fame Catcher Roger Bresnahan played between 1897 - 1915. Bresnahan most notable contributions to the game were in protective equipment. In 1905 after getting "beaned" in the head with a baseball began experimenting with head gear similar to the leather football helmet of the period that were made by A.J. Reach. Sliced vertically: one half for covering the left side of a right handed batter's head, the other for the lefty hitter. Two years later in 1907 he devised catcher's shin guards. He was the only catcher using them. Ignoring the ridicule, it was not thought to be gentlemanly to use them. By 1909 the design was refined, and became accepted, and more wildly used. I will leave a link below for more information. -Steven KeyMan
Hockey helmets were also not used till the 1970s and were directed by the National Hockey League during 1979-1980.
The NFL (National Football Leage) did not make the plastic helmets mandatory until the year 1943 because of concussions from the rubber helmets that were used before.
