Ludwig Andreas von Feuerbach was a German anthropologist and philosopher, best known for his book The Essence of Christianity, which provided a critique of Christianity that strongly influenced generations of later thinkers, including Charles Darwin, Karl Marx, Sigmund Freud, Friedrich Engels, Richard Wagner, and Friedrich Nietzsche.
An associate of Left Hegelian circles, Feuerbach advocated atheism and anthropological materialism. Many of his philosophical writings offered a critical analysis of religion. His thought was influential in the development of historical materialism, where he is often recognized as a bridge between Hegel and Marx.
