The organization was founded on June 4, 1892, by a group of 162 California residents. The Sierra Club's first president was John Muir, a pioneer in the promotion of national parks and the protection of the environment.
An article (abbreviated to ART) is a word (prefix or suffix) that is used alongside a noun to indicate the type of reference being made by the noun. Articles specify grammatical definiteness of the noun, in some languages extending to volume or numerical scope.
