Full context:   Josiah Warren is widely regarded as the first American anarchist and The Peaceful Revolutionist, the four-page weekly paper he edited during 1833, was the first anarchist periodical published. For American anarchist historian Eunice Minette Schuster, "[i]t is apparent [...] that Proudhonian Anarchism was to be found in the United States at least as early as 1848 and that it was not conscious of its affinity to the Individualist Anarchism of Josiah Warren and Stephen Pearl Andrews. [...] William B. Greene presented this Proudhonian Mutualism in its purest and most systematic form". Henry David Thoreau was an important early influence in individualist anarchist thought in the United States and Europe. Thoreau was an American author, poet, naturalist, tax resister, development critic, surveyor, historian, philosopher and leading transcendentalist, who is best known for his book Walden, a reflection upon simple living in natural surroundings, and his essay Civil Disobedience, an argument for individual resistance to civil government in moral opposition to an unjust state. Later, Benjamin Tucker fused Stirner's egoism with the economics of Warren and Proudhon in his eclectic influential publication Liberty.
