The 1933 Solvay Physics Conference:
The predecessors of modern physics conventions, the Solvay conferences started in 1911 and brought together some of the greatest scientists of the age. The seventh conference, held in Brussels in 1933, was the last such meeting that Marie Curie would attend. Under the chairmanship of Paul Langevin, the assembled physicists would discuss the implications of Chadwick’s discovery of the neutron. One year later it was the discovery of artificial radioactivity by the Joliot-Curie. .
