About John Muir

John Muir (1838-1914) was America's most famous naturalist and conservationist. He is also one of California's most important historical personalities. He has been called "The Father of our National Parks", "Citizen of the Universe", Wilderness Prophet." As an explorer, he is famous for his exciting adventures in California's Sierra Nevada, Alaska's glaciers, and world wide travels in search of nature's beauty. As a writer, he has taught millions the importance of enjoying and protecting our natural wildlife. His writings contributed greatly to the creation of Yosemite, Sequoia, Mount Rainier, Petrified Forest, and The Grand Canyon National Parks. Muir has many places named in his honor such as the Muir Woods National Monument, the John Muir Trail, and Muir College (UCSD).

His words and deeds helped inspire President Theodore Roosevelt's innovative conservation programs, including establishing the first National Monuments by Presidential Proclamation, and Yosemite National Park by congressional action.


In 1892, John Muir and other supporters formed the Sierra Club "to make the mountains glad." John Muir was the Club's first president, an office he held until his death in 1914. Muir's Sierra Club has gone on to help establish a series of new National Parks and a National Wilderness Preservation System.

The Sierra Club now has over 1.3 million members and supporters and it is the oldest, largest, and most influential environmental organization in the United States.
