Before the Institute could really develop their approach, however, they were forced into exile by the ascendancy of the Nazi Party to power in 1933. The Frankfurt School was doubly damned, being not only "left-wing radicals" but Jewish to boot. Initially scattered throughout Europe in exile, their next permanent base would be Columbia University in New York, with which they formed an association which would last from July 1934 until early 1943. Their financial needs were met by an endowment from Weil, so they were able to remain relatively independent and free to carry out their own work.
After the war, only Horkheimer and Adorno returned to Frankfurt, the others preferring to remain in America. The tone of their works became, if anything, more melancholy and distressed as they realized that the the culture of German-Jewish intellectuals from which they had emerged was now hopelessly lost. Nevertheless, they both assumed academic posts at Frankfurt and carried on their theoretical work, which-especially for Adorno-was far more oriented towards memory and meditation on the past than toward a diagnosis of the present. This is evidenced in the subtitle of one of Adorno's last books: Minima Moralia: Reflections From a Damaged Life. In it, he lamented the culture destroyed by fascism while attempting to exorcise his guilt at having survived the war. All this he managed to sum up beautifully in one sentence: "To write poetry after Auschwitz is barbaric."
