John Muir (21 April 1838 – 24 December 1914[1]) was a Scottish-born American naturalist, author, writer, and early advocate of preservation of wilderness in the United States.

His letters, essays, and books telling of his adventures in nature, especially in the Sierra Nevada mountains of California, have been read by millions of people. John Muir walked from the Midwest to the Gulf of Mexico and kept a journal of his travels called A Thousand-Mile Walk. Muir felt that the national parks and forests needed to be preserved and some resources which should be off-limits to industrial use.[2] His activism helped to preserve the Yosemite Valley, Sequoia National Park and other wilderness areas all over the United States. The Sierra Club, which he founded, is now one of the most important conservation organizations in the United States.

One of the most well-known hiking trails in the U.S., the 211-mile (340 km) John Muir Trail, was named in his honor.[3] Other places named in his honor are Muir Woods National Monument, Muir Beach, John Muir College, Mount Muir, Camp Muir and Muir Glacier. For his outstanding accomplishments in preserving America's environment, he is known to many as the "Father of the National Parks".

In 1867, when he was 29, he was blinded in a factory accident when his right eye was pierced by a file.[4]
