PresentationSilicosis decimated tens of thousands of miners and other workers in industrialised countries throughout the 20th century and is now rampant in emerging countries. The official medical definition of the disease was reached in 1930 at an international conference in Johannesburg, organized with the ILO. The consequences of this pivotal moment have reverberated down the decades, and eighty-three years later are still hampering medical research.Economic factors played a major role in the 1930 conference. The forum deliberately excluded from its frame of reference the analysis of certain modes of exposure to risk, of certain dangerous professional activities or environments, thereby neglecting a wide range of pathologies. To this day, the origin of a number of these pathologies remains disputed, but epidemiological results point to crystalline silica &#8211; the most common mineral component of the earth&#8217;s crust &#8211; as a possible causal factor.Researchers are increasingly taking an interest in these diseases, which are based on inflammatory processes and trigger systemic perturbations that are notoriously difficult to treat. This colloquium will contribute to this interrogation by bringing together different fields of research. It will return to the roots of our medical knowledge of silicosis in order to nourish contemporary medical research; and will use current medical issues to critically re-examine the historical sources.This unprecedented interdisciplinary experiment will see medical experts, epidemiologists and historians unite with sociologists, biologists and physicists to rethink inherited diagnostic categories and question the very foundations of current medical knowledge of silica hazards.ProgramTuesday 24 September 20139-9.30am: Welcome9.30am-12.30pm: CEVIPOF, salle Georges Lavau, 98 rue de l&#8217;Universit&#233;, 75007 ParisSession 1 &#8211; Silica hazards: historical and medical relevanceChair: Emily Spieler (Northeastern University &#38; MIT)David Rosner (Columbia University) &#38; Gerald Markowitz (City University of New York), Silicosis: The Paradigmatic Disease of Modern SocietyPaul-Andr&#233; Rosental (Sciences Po &#38; INED) &#38; the Silicosis team, Contextualising the international recognition of 'silicosis' in the 1930s to measure the effects of silica in the world today.
