Alexandre Béguyer de Chancourtois was a geologist, but this was at a time when scientists specialised much less than they do today. His principal contribution to chemistry was the 'vis tellurique' (telluric screw), a three-dimensional arrangement of the elements constituting an early form of the periodic classification, published in 1862.

22. Okt. 2018 · French mineralogist Alexandre-Émile Béguyer de Chancourtois developed a system to arrange all the then-known elements according to their relative atomic masses. He marked the positions of the 60 known elements on a scale showing increasing atomic mass, but then wrapped the scale in a helical fashion around a cylinder of ...
22. Feb. 2019 · In 1862 the French geologist Alexandre-Émile Béguyer de Chancourtois published a paper describing a classification of the elements. De Chancourtois' 'telluric screw', as he called it, placed the elements in order of atomic weight in a spiral pattern around a cylinder.
