In the predecessor building at 27 Beatrixgasse, Ludwig Wittgenstein’s uncle Louis lived from 1880 to 1885. Opposite, at No. 26, the writer and poet Ingeborg Bachmann (1926–1973) lived from 1946 to 1949; she engaged with Wittgenstein’s work and probably contributed to his becoming better known in the German-speaking world. At No. 18, Adalbert Stifter lived from 1837 to 1839. Stifter, incidentally, founded the Realschule in Steingasse in Linz, which Wittgenstein attended.
