The paper addresses the methodological tensions between Husserl’s phenomenology and history by reinterpreting the Addendum III of the Krisis-work in view of genetic phenomenology. Thus, the paper starts out by retracing the traditional criticism against the unhistorical character of Husserl’s phenomenology as voiced by Heidegger, Adorno and others. Afterwards, it moves on to analyse the troubled relationship between static and genetic phenomenology, on the one hand, and between genetic phenomenology and empirical genesis, on the other hand. Finally, it arrives at a step by step methodological reconstruction of Husserl’s considerations on the “origin of geometry”, which are regarded to be an application of the methods of genetic phenomenology to the field of history.
