Ludwig Andreas von Feuerbach (German: [ˈluːtvɪç ˈfɔʏɐbax]; 28 July 1804 – 13 September 1872) 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, Mikhail Bakunin, Richard Wagner, Frederick Douglass, and Friedrich Nietzsche. An associate of Young Hegelian circles, Feuerbach advocated anthropological materialism.
