The Solvay Institute of Sociology [SIS; Institut de Sociologie Solvay] assumed its first "definitive form" (Solvay 1902/1906: 26)[1] on November 16, 1902, when its founder Ernest Solvay, a wealthy Belgian chemist, industrialist, and philanthropist, inaugurated the original edifice of SIS in Parc Léopold (BS 2006). Under the guidance of its first director, Emile Waxweiler, SIS expressed a "conception of a sociology open to all of the disciplines of the human sciences: ethnology, of course, but also economics [...] and psycho-physiology, contact with which was facilitated by the proximity of the Institute of Physiology" (Vatin 1996: 486).[2] While SIS is now part of the Université Libre de Bruxelles and known more simply as that university's Institute of Sociology [Institut de Sociologie], the approach instigated by Solvay and Waxweiler still serves as methodological framework: a synergy between basic and applied research involving interdisciplinary studies firmly anchored in social life (IS 2007).
