 It was in that building that the famous Fifth Solvay Conference on Physics and on Chemistry took place in October 1927.During the following years, a campus for the Solvay School of Commerce was established but construction of additional buildings was soon curtailed for fear of encroachment on the park and its fragile wildlife.In 1930, the Lycée Émile Jacqmain secondary school moved into the former Institute of Physiology.
