John Muir

<strong>John Muir</strong> (1838-1914) was one of the most influential conservationists and nature writers in American history. He was instrumental in the creation and passage of the National Parks Act, and founder of the Sierra Club, acting as its president until his death. Muir was a spirit so free that all he did to prepare for an expedition was to "throw some tea and bread into an old sack and jump the back fence."
