Alphonse Toussenel (March 17, 1803 – April 30, 1885) was a French naturalist, writer and journalist born in Montreuil-Bellay, a small meadows commune of Angers; he died in Paris on April 30, 1885. A utopian socialist and a disciple of Charles Fourier, he was anglophobic and anti-semitic. He was at one time editor-in-chief of the newspaper La Paix, and his studies of natural history served as a vehicle for his political ideas. He was also the brother of teacher and translator Théodore Toussenel.
