Try the 1927 Solvay Conference on Electrons and Photons:

Schrödinger, Pauli, Heisenberg, Dirac, de Broglie, Bohr, Planck, Curie, Lorentz, Einstein... the number of Nobel Prizes here is left as an exercise.

But John von Neumann wasn't there for the conference and he was there for the Manhattan Project.

Those are a lot of the same people from the Manhattan project though, no?

Has something on that scale happened since, with an unrelated set of people?

Actually this conference was largely from a previous generation of scientific thinkers. According to their Wikipedia bios, Niels Bohr was the only one of those 10 names involved in the Manhattan Project. Einstein wrote a letter alerting President Roosevelt to the possibility of a German atomic bomb which may have helped inspire the project. Heisenberg was also involved in the war effort but "knew little of the Manhattan Project, so, if he were captured, he would have little intelligence value to the Germans".
