John Muir was a prominent Scottish-American biologist, author, ecological philosophy, botanist, zoologist, glaciologist, and early supporter for the conservation of wilderness in the US of America. He was also called "John of the Mountains" and "Dad of the National Parks."

Countless people have listened to his letters, essays, and books on his exploits in nature, especially in the Sierra Nevada. His effort contributed to the defense of Yosemite Valley and Sequoia National Forest, and his example has motivated the conservation of many other natural areas. The Sierra Club, which he co-founded, is a popular preservation group in the United States. Muir spent much of his later life to the conservation of the Western woods. Muir released two landmark posts on wilderness conservation in The Century Publication as part of the project to make Yosemite a national forest, "The Treasures of the Yosemite" and "Functions of the Proposed Yosemite National Forest," which helped support the push for the U.S.A. Congress to pass an expense developing Yosemite National forest in the year 1890. His works have motivated listeners, including but not limited to presidents and legislators, to do something about it to help save huge natural areas simply because of the spiritual character and enjoyment for nature shown in them.
