 Husserl developed these ideas in Göttingen, where—thanks to his Logical Investigations and the support by Wilhelm Dilthey, who admired that work and recommended Husserl to the Prussian ministry of culture—he received an associate professorship (“Extraordinariat”, later turned into a “Persönliches Ordinariat”) in 1901. From 1910/11 and 1913, respectively, he served as founding (co-)editor of Logos (in the first issue of which his programmatic article “Philosophy as a Rigorous Science” appeared, containing a critique of naturalism) and of the Yearbook for Phenomenology and Phenomenological Research (opening with his Ideas Pertaining to a Pure Phenomenology and to a Phenomenological Philosophy). Husserl stayed in Göttingen until 1916. It is here that he made his most important philosophical discoveries (cf. Mohanty 1995), such as the transcendental-phenomenological method, the phenomenological structure of time-consciousness, the fundamental role of the notion of intersubjectivity in our conceptual system, the horizon-structure of our singular empirical thought, and more. In later works—most notably in On the Phenomenology of the Consciousness of Internal Time (1928), Formal and Transcendental Logic (1929), Cartesian Meditations (1931), The Crisis of European Sciences and Transcendental Phenomenology (1954) and Experience and Judgement (1939)—these results were developed further and put into new contexts, such as the path-breaking project of linking the basic notions of science back to their conceptual roots in the pre-scientific (regions of the) “lifeworld” (Crisis).
