John Muir (1838–1914) was a Scottish-born American naturalist, writer, and conservationist, widely regarded as the "Father of the National Parks." His advocacy for wilderness preservation played a crucial role in the establishment of Yosemite National Park and Sequoia National Park in California.
Muir emigrated to the United States in 1849, settling in Wisconsin. After an industrial accident nearly cost him his eyesight, he devoted himself to nature, traveling extensively and documenting his experiences. His writings, filled with spiritual reverence for the natural world, inspired public support for conservation efforts.
In 1892, Muir co-founded the Sierra Club, which became a leading environmental organization. His advocacy influenced President Theodore Roosevelt, who visited Yosemite with Muir in 1903, leading to stronger federal protections for national parks.
Muir’s legacy continues to shape environmental movements, and his writings remain influential in discussions on wilderness preservation and ecological awareness.
