Fifth Solvay Conference (Brussels 1927)

Perhaps the most famous conference was the Fifth Solvay Conference on Electrons and Photons held from 24 to 29 October 1927, where the world's most notable physicists met to discuss the newly formulated quantum theory. The leading figures were Albert Einstein and Niels Bohr. 17 of the 29 attendees were or became Nobel Prize winners, including Marie Curie, who alone among them, had won Nobel Prizes in two separate scientific disciplines.
