André Bloch
1893–1948André Bloch wrote mathematical papers, including on Bloch's constant, while confined in Charenton asylum and sent letters without noting his institutional address.
Particulars
After the murders, André Bloch was committed to the asylum at Charenton in Saint‑Maurice, a suburb of Paris, and he continued his mathematical career while confined.
All of his publications, including those concerning Bloch's constant, were written while he was committed. He corresponded with mathematicians such as Georges Valiron, George Pólya and Jacques Hadamard, giving his return address as “57 Grande rue, Saint‑Maurice” and not indicating that it was a psychiatric hospital, so several correspondents were unaware of his confinement.
