In 1946 a conference was held at Princeton University on the occasion of its 250th anniversary. The conference was extraordinary, as it was attended by many prominent mathematicians of the time, including von Neumann, Hermann Weyl, etc. I want to know whether there exist any proceedings containing the papers presented at the event.
The only source I found is a report published in volume 2 of the book A century of mathematics in America (edited by Peter Duren) that seems to be a reprint of the book Problems of Mathematics. It contains a brief summary of the event, and not the whole paper.
Any additional information or references would be appreciated.
