Johann Kaspar Schmidt (25 October 1806 – 26 June 1856), known professionally as Max Stirner, was a German post-Hegelian philosopher, dealing mainly with the Hegelian notion of social alienation and self-consciousness. Stirner is often seen as one of the forerunners of nihilism, existentialism, psychoanalytic theory, postmodernism and individualist anarchism. Stirner's main work, The Ego and Its Own (), was first published in 1844 in Leipzig and has since appeared in numerous editions and translations. Biography Stirner was born in Bayreuth, Bavaria. What little is known of his life is mostly due to the Scottish-born German writer John Henry Mackay, who wrote a biography of Stirner (Max Stirner – sein Leben und sein Werk), published in German in 1898 (enlarged 1910, 1914) and translated into English in 2005. Stirner was the only child of Albert Christian Heinrich Schmidt (1769–1807) and Sophia Elenora Reinlein (1778–1839), who were Lutherans. His father died of tuberculosis on 19 April 1807 at the age of 37. In 1809, his mother remarried to Heinrich Ballerstedt (a pharmacist) and settled in West Prussian Kulm (now Chełmno, Poland). When Stirner turned 20, he attended the University of Berlin, where he studied philology. He attended the lectures of Georg Wilhelm Friedrich Hegel, who was to become a source of inspiration for his thinking. He attended Hegel's lectures on the history of philosophy, the philosophy of religion and the subjective spirit. Stirner then moved to the University of Erlangen, which he attended at the same time as Ludwig Feuerbach. Stirner returned to Berlin and obtained a teaching certificate, but he was unable to obtain a full-time teaching post from the Prussian government. While in Berlin in 1841, Stirner participated in discussions with a group of young philosophers called Die Freien (The Free Ones), whom historians have subsequently categorized as the Young Hegelians. Some of the best known names in 19th century literature and philosophy were involved with this group, including Karl Marx, Friedrich Engels, Bruno Bauer and Arnold Ruge. While some of the Young Hegelians were eager subscribers to Hegel's dialectical method and attempted to apply dialectical approaches to Hegel's conclusions, the left-wing members of the group broke with Hegel. Feuerbach and Bauer led this charge. Frequently the debates would take place at Hippel's, a wine bar in Friedrichstraße, attended by among others Marx and Engels, who were both adherents of Feuerbach at the time. Stirner met with Engels many times
