[1] During his life in America, Blücher traveled in popular academic circles and appears prominently in the lives of various New York intellectuals.

Heinrich Blücher began teaching philosophy at Bard College in 1952, despite having no post-secondary education, continuing for seventeen years, as well as at the New School for Social Research.

[4] Arendt and Blücher met in 1936, in a café along the rue Soufflot frequented by their friend Walter Benjamin and other German émigrés.

Due to the pressures of lacking citizenship and their marital status, Blücher would not marry Arendt until 1940, despite accounts reporting that they fell in love immediately.

In a letter to Blücher, Arendt expressed joy at this, writing, "Yes, love, our hearts have really grown toward each other and our steps go in unison.

"[5] Blücher encouraged his wife to become involved with Marxism and political theory, though ultimately her use of Karl Marx was in no way orthodox, as shown in such works as The Origins of Totalitarianism (1951) and The Human Condition (1958).

[6] Blücher believed, alongside Arendt and Martin Heidegger, that science held a corresponding mindset which threatened first religion, and now philosophy.

"[2] Axel Milberg plays Heinrich Blücher in the film which takes place during and after Arendt's research and publication of Eichmann in Jerusalem.

[9] He is also shown to be active in the social circles Arendt and he travel in, posed in frequent heated debate with Hans Jonas.

In the movie he is seen deeply in love with Arendt, despite the indication of mutual infidelities that imply a marriage based in some form of polyamory.

He is also shown as emotionally supportive of Arendt during the fallout from the aforementioned publication, consoling her on the loss of her friend Kurt Blumenfeld.
