John Muir was the founder of the Yosemite National Park. Also known as “Father of National Parks” or “John of the Mountains,” he was an environmental philosopher, zoologist, and botanist in the USA.   John inspired travelers of Yosemite to look under the surface through his magical, poetic imagery — “Climb the mountains and get their good tidings.” His books, magazine articles, and letters raised awareness about the distinctive beauty of Yosemite.  Muir had spent years studying everything he could about the valley. He started a campaign to preserve Yosemite Valley as a national park after realizing the increasing rate of the devastation of nature’s beauty by humans and other species.  On 1st October 1890, the Yosemite Valley region became a national park.
