Lou Andreas-Salomé met Austrian psychoanalyst Sigmund Freud in 1911 at a congress of psychoanalysts in Weimar, Germany. (However, some biographers think they met as early as 1895.) She soon became associated with the Vienna circle of psychoanalysts. Salomé attended Freud’s lectures (the only woman he allowed to do so), and they began a friendship that would last to the end of her life. They frequently corresponded on topics such as narcissism and anxiety.
