Alexandre-Émile Béguyer de Chancourtois (1820-1886) was the first of the independent discoverers of chemical periodicity. He presented his system, the Vis tellurique, to the Académie des Sciences in a series of memoirs in 1862 and 1863. Published under the heading of general chemistry in the Académie's <i>Comptes Rendus</i> without the helical graph that illustrates the system, these papers attracted little attention at the time. Not long after his death, attention was drawn to his priority in a discovery for which Mendeleev, Meyer, and Newlands had received accolades. This presentation will review his career and look in detail at the Vis tellurique, including its graphical embodiment.
