At the beginning of the past century XX, the industrialist and filántropo Belgian Ernest Solvay used part of his fortune in organizing several conferences on physics to which the privileged minds more of the moment were invited.

Without a doubt most famous of all it was the fifth conference on physics that took place in October of 1927, to that attended the parents of the quantum physics and other figures already consecrated in other fields. Of that unique establishment of geniuses, reunited around thematic “Electrons and Photons”, we have left the one that stops many is the more famous scientific photography of history.

Of the 29 assistants, 17 were already, or were later, Nobel prizes.

One realizes importance of the meeting and the assistants when it recognizes the faces of Pauli, Schrödinger, Einstein, Dirac, Marie Curie, Bohr, Planck, Lorentz and Heisenberg to mention most well-known.

This is the complete list of assistants:

(Superior Row, of left to right)
A. Piccard, E. Henriot, P. Ehrenfest, Ed. Herzen, Th. Of Donder, E. Schrödinger, E. Verschaffelt, W. Pauli, W. Heisenberg, R.H. Fowler, L. Brillouin.

(Intermediate Row, of left to right)
P. Debye, M. Knudsen, W.L. Bragg, H.A. Kramers, P.A.M. Dirac, A.H. Compton, L. of Broglie, M. Born, N. Bohr.

(Inferior Row, of left to right)
I. Langmuir, M. Planck, Madame. Curie, H.A. Lorentz, A. Einstein, P. Langevin, Ch. E. Guye, C.T.R. Wilson, and O.W. Richardson.

With the perspective which they to date give the 78 passed years, and considering which their works have supposed for the physics to day of today, anyone will be able to admit that this photography represents the greater agglomeration of geniuses of history.
