John Muir (1838–1914) was a Scottish-American naturalist, author, environmental philosopher, and early advocate for the preservation of wilderness in the United States. His letters, essays, and books narrating his adventures in nature, especially in the Sierra Nevada mountain range, have been read by millions. Muir's enthusiasm for nature was boundless, and his written works expound upon his naturalist philosophy and his adventures in the wild. His book 'Steep Trails' is a collection of articles and essays that he wrote over a number of years, celebrating the beauty, spirit, and challenges of the mountain landscapes he held dear, specifically the Sierra Nevada and areas in California (Muir, 1918). In the literary realm, Muir is known for his poetic and evocative style, which not only reflects his deep knowledge of the landscapes he explored but also his personal transcendentalist philosophy that espoused a direct connection between nature and the human soul. Muir was not just an author but also an activist, his advocacy was instrumental in the establishment of national parks and his legacy is strongly tied to the conservation movement. Muir's passion and literary contribution have cemented his place as an icon in American environmentalism, earning him the nickname 'Father of the National Parks.' He co-founded the Sierra Club, an organization that is a testament to his commitment to protecting natural spaces. The club remains a leader in environmental causes to this day.
