The "Father of the National Park Service"
John Muir was many things, inventor, immigrant, botanist, glaciologist, writer, co-founder of the Sierra Club, fruit rancher. But it was John Muir's love of nature, and the preservation of it, that we can thank him for today. Muir convinced President Teddy Roosevelt to protect Yosemite (including Yosemite Valley), Sequoia & Kings Canyon, Grand Canyon and MT. Rainier as National Parks.
