 In the year 1916 Husserl became Heinrich Rickert’s successor as full professor (“Ordinarius”) in Freiburg/Breisgau, where (among many other things) he worked on passive synthesis (cf. Husserliana, vol. XI, XXXI). He gave four lectures on Phenomenological Method and Phenomenological Philosophy at University College, London, in 1922 (cf. Husserliana, vol. XXXV). In 1923 he received a call to Berlin, which he rejected. Husserl retired in 1928, his successor being his (and Rickert’s) former assistant Martin Heidegger (whose major work Being and Time had been published in Husserl’s Yearbook in 1927). In 1929 he accepted an invitation to Paris. His lectures there were published as Cartesian Meditations in 1931. In the same year, Husserl gave a number of talks on “Phenomenology and Anthropology”, in which he criticized his two “antipodes”, Heidegger and Max Scheler (cf. Husserl 1997). In 1933 Hitler took over in Germany. Husserl received a call to Los Angeles but rejected. Because of his Jewish ancestors, he became more and more humiliated and isolated. In 1935 he gave a series of invited lectures in Prague, resulting in his last major work, The Crisis of European Sciences and Transcendental Phenomenology.
