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..
BELL started by manufacturing protective headgear for auto racing. BELL moved to the leading edge of helmetry in 1957, introducing the use of a non-resilient polystyrene liner. That same year, BELL also began to supply helmets to law enforcement agencies. One of the first open face BELL helmet, the 500-TX is selected by the Museum of Modern Art in New York for Excellence of Design. Four Bell helmet models are on continuous display at MoMA.
