Hayek was also a founder of the "Geist circle" which comprised Herbert Fürth, Friedrich Engel-Janosi, Gottfried Haberler, Fritz Machlup, Oskar Morgenstern, Alfred Schutz, Felix Kaufmann, and Karl Menger. Alfred Schutz elaborated his Phenomenology of the Social World (1932) in discussion with Austrian social theory, as he sought to reconcile Husserlian philosophy with the subjectivist standpoint of the Austrians.
