Why Is Alexandre-Émile Béguyer de Chancourtois Influential?
(Suggest an Edit or Addition)According to Wikipedia, Alexandre-Émile Béguyer de Chancourtois was a French geologist and mineralogist who was the first to arrange the chemical elements in order of atomic weights, doing so in 1862. De Chancourtois only published his paper, but did not publish his actual graph with the irregular arrangement. Although his publication was significant, it was ignored by chemists as it was written in terms of geology. It was Dmitri Mendeleev's table published in 1869 that became most recognized. De Chancourtois was also a professor of mine surveying, and later geology at the École Nationale Supérieure des Mines de Paris. He also was the Inspector of Mines in Paris, and was widely responsible for implementing many mine safety regulations and laws during the time.
