Johann Kaspar Schmidt (October 25, 1806 – June 26, 1856), better known as Max Stirner was a German philosopher who was one of the forerunners in nihilism, existentialism, post-modernism, and anarchism, especially of individualist anarchism. Stirner's main work is The Ego and Its Own, also known as The Ego and His Own (Der Einzige und sein Eigentum in German, which translates literally as The Unique One and his Property). This work was first published in 1844 in Leipzig, and has since appeared in numerous editions and translations.

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). His father died of tuberculosis on the April 19, 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).

Michel Onfray (born January 1, 1959 in Argentan, Orne, France) is a contemporary French philosopher who adheres to hedonism, atheism and anarchism. He is a highly prolific author on philosophy with more than 50 written books.

He has gained notoriety for writing such works as Physiologie de Georges Palante, portrait d'un nietzchéen de gauche, Politique du rebelle: traité de résistance et d'insoumission, Traité d'athéologie: Physique de la métaphysique (translated into English as Atheist Manifesto: The Case Against Christianity, Judaism, and Islam, La puissance d'exister and La Sculpture de soi for which he won the annual Prix Médicis in 1993.

His philosophy is mainly influenced by such thinkers as Nietzsche, Epicurus, the cynic and cyrenaic schools, Julien Offray de La Mettrie, and individualist anarchism.

Born to a family of Norman farmers, he graduated with a Ph.D. in philosophy. He taught this subject to senior students at a technical high school in Caen between 1983 and 2002, before establishing what he and his supporters call the Université populaire de Caen, proclaiming its foundation on a free-of-charge basis and on the manifesto written by Onfray in 2004 (La communauté philosophique).
