This is a question about Hermann Minkowski (1864–1909) and Eugène (Eugeniusz) Minkowski (1885–1972) .
It is striking that they both worked so intensively on space-times in two different domains (Hermann in manthematics, Eugène in psychiatry).
So, I'm just wondering if there's any sort if connection between them (family conneciton, but also intellectual-cultural connection).
Thanks!
