Gary Fisher - In 1974 Gary Fisher grafted a mixture of road bike and motorcycle parts onto a 1940s Schwinn Excelsior and created the first reliable, low-maintenance mountain bike. Soon after, Gary founded Mountain Bikes, the first company to build production mountain bikes. Today, Gary Fisher Bicycles is one of the world's leading brands of performance bicycles sold through specialty retailers. As chief designer Gary Fisher continues to be one of the most creative forces in cycling with a bicycle line that includes highly engineered, American-made mountain, luxury and children's bikes. http://fisherbikes.com/
