On 28th of May 1892 The Sierra Club was formed in San Francisco by the Scottish environmentalist John Muir and others.

The Sierra Club was founded in 1892 by a group of Californians who wished to sponsor wilderness outings in “the mountain regions of the Pacific Coast.” The naturalist John Muir was its first president (1892–1914) and very soon involved the club in political action to further nature conservation. Among its first successes was the defeat of efforts to constrict the size of Yosemite National Park, which in 1905 was transferred from state to federal control.
