Émile Armand (Paris 1872-Roven 1962), pseudonym of Ernest Lucien Juin, is perhaps the most accessible and penetrating of the theorists of anarchist individualism. Essayist, poet, journalist, translator and editor, exercised great influence in certain Spanish libertarian media of the first decades of the twentieth century. He was a man of tremendous vitality and great breadth of vision, as evidenced by his extensive literary production. The thought of É. Armand revolves around three key ideas: anarchist individualism, amorous camaraderie - or unhindered sexuality - and the free grouping of individuals for life in common, without State or authority. His efforts to break down moral and sexual prejudices placed him outside his time, and ours.
