Underwood & Underwood, c. 1912; Library of Congress (public domain) · Library of Congress Prints and Photographs Division, '[John Muir, seated, reading a book]', photographer Underwood & Underwood, dated c1912 May 29 on the record, with the note 'J169749 U.S. Copyright Office' (a 1912 U.S. copyright entry), call number BIOG FILE - Muir, John, reproduction number LC-DIG-ppmsca-18943. The Library's rights statement is 'No known restrictions on publication', but the basis relied on here is item-level: a professional studio photograph published and registered in the United States in 1912, so its U.S. protection has expired by age (works published before 1931). Muir was about 74 and the sitting was a documented photograph of him, so it is a likeness.

Key Achievements

Naturalist and writer whose magazine articles led Britannica to call him largely responsible for the 1890 creation of Sequoia and Yosemite national parks; he founded the Sierra Club in 1892 and was its first president.

Wrote books that remain important in American nature literature, including The Mountains of California (1894), Our National Parks (1901) and The Yosemite (1912), plus posthumous journals such as A Thousand-Mile Walk.

In 1874-75 attributed Yosemite's formation to glacial erosion, against the then common cataclysm view; Britannica says he was the first to present this theory and that it is now generally accepted.


Moments That Reveal Them

In the early 1870s he spent his Sunday excursions from a Yosemite sawmill making detailed studies of the valley's geology, plants and animals, including the water ouzel, and worked out the idea that glaciers had shaped the valley.

This is consistent with self-directed curiosity, though the detail comes largely from Muir's own journals as retold. Curiosity

Without formal geological training he argued that glaciers, not a sudden earthquake collapse, had carved Yosemite; Joseph LeConte was impressed enough to encourage his first article, while a later geographers' review says he overstated the glaciers' extent.

This is consistent with independent thinking against the prevailing view, with some overreach. Independent Thinking


Turning Points

In 1867 an industrial accident nearly cost him an eye; he abandoned mechanical inventing and set out on a thousand-mile walk, then went to Yosemite in 1868 to devote his life to nature.

This is consistent with a self-chosen change of direction toward independent work in nature. Need for Autonomy
