I ask because resulting from my recent posting of "further remarks on
Bourbaki" a statement has reached me (from an anonymous French source,
filtered through two other people) that Mandelbrojt (who, I understand,
left Poland for France in 1920) was kept out of university positions for
most of his life by a Bourbachiste veto.
I notice the curious fact that he is listed as one of the founding fathers
of Bourbaki by Chevalley, by the sister of Cavailles, and by Corry in his
Synthese article; but is omitted from that list by Armand Borel and by
Pierre Cartier.
So any information about the scope of Mandelbrojt's mathematical work, and
about his involvement with Bourbaki, and any psychological insights into a
possible estrangement from Bourbaki, would be most welcome.
