The most smartest photo ever

In 1927, an event brought together some of the world's greatest minds in one room. That year, 29 scientists met in Brussels for the fifth Solvay Congress. Convened by the Belgian chemist and industrialist Ernest Solvay, the topic of that year’s conference was “Electrons and photons”, topics discussed in the new theories of quantum mechanics. 

Among them were Nobel laureates and professors with prestigious university departments, including legendary names such as Marie Curie, Albert Einstein, Niels Bohr and Erwin Schrödinger. During the event, attendees gathered for what was described as the "smartest photo" of all time: a simple snapshot of one of the most emotional moments.

Photographer Benjamin Couprie captured in 1927 what is considered a historic photograph in science.
