Max Stirner

the first ever catboy and the father of Egoism.

Johann Kaspar Schmidt (25 October 1806 – 26 June 1856), better known as Max Stirner, was a German philosopher who is often seen as one of the forerunners of nihilism, existentialism, psychoanalytic theory, postmodernism and individualist anarchism.89

Stirner's main work The Ego and Its Own (German: Der Einzige und sein Eigentum; meaningfully translated as The Individual and his Property, literally as The Unique and His Property) was first published in 1845 in Leipzig and has since appeared in numerous editions and translations.
