Here is a translation into British English: At Lange Gasse 72, Florianigasse 42 and Währingerstraße 33–35 in Vienna, memorial plaques commemorate the mathematician Kurt Gödel, who lived at these addresses between 1927 and 1929 and took part in meetings of the Vienna Circle. There are indications of a mutual reception between Gödel and Ludwig Wittgenstein, who also examined the philosophical foundations of mathematics. However, there is no evidence that the two ever met in person.
