Robert Boyle, The Sceptical Chymist

As we celebrate chemical compliments, we might send illustratively-arranged birthday greetings to Alexandre-Émile Béguyer de Chancourtois; he was born on this date in 1820. A geologist and mineralogist, he was the first to arrange the chemical elements in order of atomic weights (in 1862). But De Chancourtois only published his paper, not his graph with the novel arrangement; and because it was a geology paper, it was largely ignored by chemists. It was Dmitri Mendeleev’s table, published in 1869, that became the standard– and the model for the periodic table that we know today.
