At the Vienna Konzerthaus, Wittgenstein’s brother Paul, who gained fame as a one-armed pianist, used to perform. In the stairwell, Wittgenstein’s grandnephew, Pierre Stonborough – the grandson of his sister Margaret Stonborough – is honoured as a patron of the Vienna Konzerthaus Society.
The website of the Konzerthaus features the programme of a concert held on 8 January 1928, in which Paul Wittgenstein appeared as the pianist.
