The autobiographical essay, written in 1963 as a contribution to the Festschrift for Max Niemeyer in honor of his 80th birthday, describes Heidegger’s way into phenomenology. Franz Brentano’s dissertation, Carl Braig’s treatise on being, and Edmund Husserl’s Logical Investigations were very important for his philosophical development. He also refers to the writing of Emil Lask. From 1919 on, he learned much from Husserl as his assistant. His rethinking of Aristotle would lead to his lifelong topic of the question of being. The first edition of Being and Time was published by Max Niemeyer, who in 1953 also published the Introduction to Metaphysics.
