Stephen Mather, a millionaire businssman, mobilized public support in 1916 for creation of a new agency, the National Park Service, whose sole responsibility would be protecting the parks. He then became its first director and molded the haphazard collection of parks into a cohesive system. Noted for his enthusiasm and energy, Mather was also prone to crippling bouts of depression. He sought solace in the parks. Source: Harper's Ferry Center, Historic Photo Collection.
