Chemist Ernest Solvay and engineer Zenobe Gramme (École industrielle de Liège) gave their names to the Solvay process and the Gramme dynamo, respectively, in the 1860s. Bakelite was developed in 1907–1909 by Leo Baekeland. Ernest Solvay also acted as a major philanthropist and gave its name to the Solvay Institute of Sociology, the Solvay Brussels School of Economics and Management and the International Solvay Institutes for Physics and Chemistry which are now part of the Université libre de Bruxelles. In 1911, he started a series of conferences, the Solvay Conferences on Physics and Chemistry, which have had a deep impact on the evolution of quantum physics and chemistry. A major contribution to fundamental science was also due to a Belgian, Monsignor Georges Lemaître (Catholic University of Louvain), who is credited with proposing the Big Bang theory of the origin of the universe in 1927.
