Solvay Conference


The International Solvay Institutes for Physics and Chemistry, located in Brussels, were founded by the Belgian industrialist Ernest Solvay in 1912, following the historic invitation-only 1911 Conference, considered a turning point in the world of physics. The Institutes coordinate conferences, workshops, seminars, and colloquia.
Following the initial success of 1911, the Solvay Conferences have been devoted to outstanding preeminent open problems in both physics and chemistry. The usual schedule is every three years, but there have been larger gaps.

Notable Solvay Conferences

First Conference

was chairman of the first Solvay Conference held in Brussels from 30 October to 3 November 1911. The subject was Radiation and the Quanta. This conference looked at the problems of having two approaches, namely classical physics and quantum theory. Albert Einstein was the second youngest physicist present. Other members of the Solvay Congress included such luminaries as Marie Curie and Henri Poincaré.

Third Conference

The Third Solvay Conference was held in April 1921, soon after World War I. Most German scientists were barred from attending. In protest at this action, Albert Einstein, himself a citizen and a vocal supporter of the infant Weimar Republic, declined his invitation to attend the conference where most of his countrymen were barred. However, the real reason of Einstein's absence is because he accepted the invitation by Dr. Chaim Weizmann for a trip to the United States.

Fifth Conference

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.
