1. A GROUP FORM
mathematicians held positions at univerisities outside of Paris:
Cartan and Weil were at Strasbourg, Delsarte at Nancy, Dieudonne at
Rennes, and de Possel at Clermont-Ferrand. They were in Paris for
the Julia Seminar, held at 4:30 pm at the newly founded Henri
Poincare Institute on the second and fourth Mondays of each month
of the academic year.
What did they say during this first meeting? We can answer this
thanks to the work of Liliane Beaulieu, a mathematical historian from
Quebec, who had access to the minutes of Bourbaki's meetings. For
Weil, who already seemed to have precise ideas about what he and
his friends should set out to accomplish together, it was necessary to
"establish the content of the differential and integral calculus certifi-
cate for twenty-five years by writing a treatise on analysis" and that
this treatise would be "as modern as possible." Weil anticipated that
the publisher would be Hermann, where he knew the director,
Enrique Freymann. Delsarte strongly supported the idea that the
book, covering a wide range of material, would be written collec-
tively. Animated discussion about the size of the project, the
