Hannah Arendt
In 1936, Arendt met the self-educated Berlin poet and Marxist philosopher Heinrich Blücher (1899–1970) in Paris. Blücher had been a Spartacist and then a founding member of the KPD, but had been expelled due to his work in the "Versöhnler" (Conciliator faction). Although Arendt had rejoined Stern in 1933, their marriage existed in name only, with them having separated in Berlin. She fulfilled her social obligations and used the name Hannah Stern, but the relationship effectively ended when Stern, perhaps recognizing the danger better than her, emigrated to America with his parents in 1936. In 1937, Arendt was stripped of her German citizenship and she and Stern divorced. She had begun seeing more of Blücher, and eventually they began living together. It was Blücher's long political activism that began to move Arendt's thinking towards political action. Arendt and Blücher married on January 16, 1940, shortly after their respective divorces were finalized.
