John Muir was born on April 21, 1838, in Dunbar, Scotland. He was an extremely skilled inventor who won prizes. Muir got an eye-blinding injury at work that would change his life path completely. He turned to protect the environment, going to all different places. He came across Yosemite in California, and it captivated him. He was angry to see it being destroyed by miners and loggers, so he wrote articles urging laws to protect the wilderness. By 1890, John Muir's writings gained enough public support that Congress was finally convinced to create Yosemite National Park. He later was involved with many other important projects, and with many of his supporters, they eventually founded the Sierra Club. Later on, he became friends with Theodore Roosevelt and together helped to save the wilderness. Muir eventually died on December 24, 1914, after visiting his daughter in the hospital. With all he has done, many say that he was perhaps this country's most famous and influential naturalist and conservationist.
Starting at 1876, John Muir wrote articles in popular periodicals to urege the feseral government to adopt a forest conservation polocy. In 1892, he founded the Sierra Club and server as its first president until his death.
