The 19th century pioneers of social theory and sociology, like Saint-Simon, Comte, Marx, John Stuart Mill or Spencer, never held university posts and they were broadly regarded as philosophers. Emile Durkheim endeavoured to formally established academic sociology, and did so at the University of Bordeaux in 1895, he published "Rules of the Sociological Method". In 1896, he established the journal "L'Année Sociologique". Durkheim's seminal monograph, "Suicide" (1897), a case study of suicide rates amongst Catholic and Protestant populations, distinguished sociological analysis from psychology or philosophy.
