In the 1920s, Margaret Stonborough, sister of Ludwig Wittgenstein, lived at Palais Schönborn-Batthyány in Vienna. During this time, she commissioned the construction of Palais Stonborough, now known as Wittgenstein House, in Vienna’s 3rd district, a project in which Ludwig Wittgenstein played a central role. Palais Schönborn was also the site of the first meeting between Ludwig Wittgenstein and Moritz Schlick of the Vienna Circle.

From 21-27 October 2025, the Wittgenstein Initiative hosted the "WITTGENSTEIN WEEK 2025" in the Beletage of Palais Schönborn, featuring lectures, discussions, and an exhibition.

WITTGENSTEIN WEEK 2025: The Wittgenstein Houses (Wittgenstein Initiative)

The exhibition "Scientific World-Conception in Vienna – Places of the Vienna Circle" at the Vienna Library in City Hall (5 June to 19 September 2025) presented the ideas and meeting places of the Vienna Circle in their scientific, social, and political context. The influential circle around Moritz Schlick first appeared in public in 1929, shaped the cultural life of “Red Vienna,” and was almost entirely driven into exile after 1938.

At these meetings, Wittgenstein’s Tractatus was also discussed in depth. Wittgenstein himself declined invitations to attend the meetings, but met with Schlick and Waismann in smaller groups.

By the way, one of the last paternoster lifts is still in operation in Vienna’s City Hall.

From 1925 to 1928, Ludwig Wittgenstein was repeatedly registered at Kriehubergasse 25 in Vienna’s 5th district. This was the residence of Ludwig Hänsel, a friend of Wittgenstein since their time together as prisoners of war.

Friedrich Waismann, a member of the Vienna Circle, resided at Fruchtgasse 3 in Vienna’s second district. Between 1927 and 1936, he engaged in a series of discussions with Ludwig Wittgenstein and soon came to serve as a kind of "spokesperson" for Wittgenstein in relation to the Vienna Circle. Wittgenstein, however, disclaimed any responsibility for Waismann’s interpretations and later distanced himself from him entirely. Waismann’s notes were published posthumously in 1967.

At 68 Prinz-Eugen-Straße in Vienna’s 4th district lived Moritz Schlick, the leading figure of the Vienna Circle. From the summer of 1927 onwards, regular meetings took place between Schlick, Ludwig Wittgenstein, and selected members of the Circle. It soon became clear, however, that Wittgenstein was by no means the positivist he had initially been taken to be (Monk, 1991, p. 243).
