Sylvère Lotringer (1938–2021) was the founding editor of Semiotext(e). He lived in New York and Baja, California, and was Jean Baudrillard Chair at the European Graduate School, Switzerland, and Professor Emeritus of French literature and philosophy at Columbia University. As Franco “Bifo” Berardi and Christian Marazzi write, Lotringer “was a volcanic organizer of cultural innovation, a radical experimenter in existential adventures, and a wonderful friend.”
