Paul-Henri Thiry, Baron d'Holbach (1723-1789) was a French-German author, philosopher, encyclopedist and a prominent figure in the French Enlightenment. He was born Paul Heinrich Dietrich in Edesheim, near Landau in the Rhenish Palatinate, but lived and worked mainly in Paris, where he kept a salon. He is best known for his atheism, and for his voluminous writings against religion, the most famous of them being the System of Nature (1770). For the Encyclopedie d'Holbach authored and translated a large number of articles on topics ranging from politics and religion to chemistry and mineralogy. As a German who had become a naturalised Frenchman, he undertook the translation of many contemporary German works of natural philosophy into French. All in all, between 1751 and 1765 he contributed some four hundred articles to the project, mostly on scientific subjects, in addition to serving as the editor of several volumes on natural philosophy. D'Holbach may also have written several disparaging entries on non-Christian religions, intended as veiled criticisms of Christianity itself.
