Clarence Lee Swartz (1868–1936) was an American individualist anarchist, whose best-known work, What is Mutualism?
He worked in the mechanical department of Liberty beginning in 1891,[2] edited an anarchist journal called Voice of the People[3] and served as assistant editor for Moses Harman's journal Lucifer, the Light-Bearer in 1890.

[5] In 1908, Tucker's publishing business, including most of his books and plates, were destroyed in a fire and after Tucker retired from publishing and moved to Europe, "practically all of the literature of individualist anarchism [went] out of print".
In 1923 he worked together with Charles T. Sprading and J. William Lloyd on The Libertarian, a magazine opposed to blue laws, Prohibition and the censorship of arts and entertainment.
