On June 1, 1979, the NHL enacted a rule requiring the wearing of helmets for anyone entering the league after that date, though a âgrandfatherâ clause allowed diehard veterans to continue to go hatless if they wished.
In 1964, the Phillies' Tony GonzÃ¡lez was the first to wear a batting helmet with a pre-molded earflap. Prior to this, earflaps had been improvised. GonzÃ¡lez was in the league top-ten in hit by pitches and the special helmet was constructed for his use.
