Two such letters (one quoted in its entirety and one excerpted) appear
in the original French in Weil's Collected Papers (volume I, pages 244-255).
My French is not so fluent, so before I dive in with dictionary in hand
I thought I'd ask whether anyone knows of an existing English translation.
I tried using Altavista to see if perchance the text exists on-line in
either French or English; amusingly, the search for "Weil Rouen 1940"
turned up the home-page of an artist named Mandeville who was born in
Rouen, had his first shows during the period 1939-1941, and whose first
post-World War II exhibition was held in 1958 at the "Galerie Andre Weil"
in Paris.
