John Clark was born in New Orleans, Louisiana, on August 21, 1945, where his family had resided for twelve generations.

[1] Some of Clark's earliest published works included a critique of Young Hegelian Max Stirner's egoism (1977), as well as The Philosophical Anarchism of William Godwin (1977).

With Camille Martin, this culminated in A Voyage to New Orleans: Anarchist Impressions of the Old South (2004) and Anarchy, Geography, Modernity: Selected Writings of Elisée Reclus (2005, 2013), for which he also provided commentary.

[3] In 2013, Clark published The Impossible Community: Realizing Communitarian Anarchism, a dialectical contribution to contemporary anarchist theory rooted in but differentiated from the social ecology of Murray Bookchin.

The John P. Clark Papers are housed in the Special Collections and Archives of the J. Edgar and Louis S. Monroe Library, containing primarily correspondence and publications.
