Abstract
The article records the three stages of work undertaken to assemble a single organized corpus of Simmel’s dispersed writings after his death in September 1918. This incudes a first phase of work by Gertrud Simmel and Gertrud Kantorowicz from the years of the Weimar Republic, a second phase from the post-1945 period, overseen by Michael Landmann and Kurt Gassen, and a third phase, inaugurated in the 1980s by a team of scholars at Bielefeld University headed by Otthein Rammstedt and – initially – Niklas Luhmann, which resulted in the 24 volumes in print today with Suhrkamp Verlag.
