This article provides a detailed account of the year that Michel Foucault spent as Director of the Institut Français in Hamburg and as a guest lecturer at the Romance Studies Department at the University of Hamburg. It discusses the beginning of Foucault’s time in Hamburg, the courses he taught at these two institutions, his interactions with German students in his classes, and events with invited guests from the French intellectual sphere. But it also sheds light on the friendships he made in Hamburg, in particular with Rolf Italiaander; the completion of his own projects including Histoire de la folie and the translation of Kant’s Anthropology from a Pragmatic Point of View; and finally his nocturnal wanderings through Hamburg’s red light district, Sankt-Pauli.
