history, part I: On November 16 1842, Marx first met Engels at the offices of Rheinische Zeitung in Cologne, where Marx was an editor. They would become friends two years later when they met again in Paris, following which they became life long collaborators.
Marx, edited by Engels: […] “the human essence is no abstraction inherent in each single individual. In its reality it is the ensemble of the social relations.” (Theses on Feuerbach, 1845).
