David Émile Durkheim was a French sociologist. Durkheim formally established the academic discipline of sociology and is commonly cited as one of the principal architects of modern social science, along with both Karl Marx and Max Weber.
Much of Durkheim's work concerns the inability of societies to maintain their integrity and coherence in modernity, an era in which traditional social and religious ties are much less universal, and in which new social institutions have come into being. Durkheim's conception of the scientific study of society laid the groundwork for modern sociology. He used such scientific tools as statistics, surveys, and historical observation in his analysis of suicides in Roman Catholic and Protestant groups.
Durkheim's first major sociological work was De la division du travail social (1893; The Division of Labour in Society), followed in 1895 by Les Règles de la méthode sociologique (The Rules of Sociological Method). Also in 1895 Durkheim set up the first European department of sociology and became France's first professor of sociology.
