James Klagge drew my attention to this essay on Wittgenstein's time in Swansea. I don't think I knew that Wittgenstein lived in Mumbles (at 10 Langland Road, which is just over half a mile from where I used to live when I studied at Swansea). It's one of the New York Times' 52 places to love in 2021 (the first one listed, so you won't have to scroll too much if you click on the link).
My mother also once lived about half a mile from Wittgenstein (as the crow flies). In 1938 he lived at 81 East Road, Cambridge and she was a baby, living at 57 Cromwell Road. Apart from the fact that he wrote this nine years earlier, she could have inspired this thought:
Anyone who listens to a child’s cry and understands what he hears will know that it harbors dormant psychic forces, terrible forces, different from anything commonly assumed. Profound rage, pain, and lust for destruction.
The famous picture of Wittgenstein below was taken at the Mumbles train shelter (not, I think, in Mumbles, but at the station nearest the university on the line that ran between Swansea and Mumbles). At least, the article linked to above says it was taken "in the, now demolished, Mumbles Train shelter on Swansea promenade, at the bottom of Brynmill Lane." My guess is that the shelter was at the Brynmill station. So this is Wittgenstein by the seaside.
