De chancourtois was a french geologist who was the first to organize the elements by atomic weights he plotted a graph of the elements around a cylinder with a circumference equal to 16 units to correspond to the weight of oxygen the elements that appeared above and below each other shared similar periodic properties between each other. The periodic table appears to have been independently formulated by at least six people within one decade: de chancourtois, newlands, meyer, and mendeleev, as well as hinrichs, and odling in 1894 ramsay isolated argon, and in the next year discovered helium. The history of the periodic table reflects over a century of growth in the understanding of chemical properties the most important event in its history occurred in 1869, when the table was published by dmitri mendeleev, alexandre-emile béguyer de chancourtois.
A collection of historic documents that led to the development of the modern periodic table (clockwise from top left) – lavoisier's 'table of simple substances' (1789) de chancourtois' 'telluric screw' (1862) mendeleev's hand-written periodic table (1869) a modern periodic table (2016) john dalton's list of atomic weights & symbols. Alexandre-emile beguyer de chancourtois was a french geologist and mineralogist born on january 20, 1820 – died on november 14, 1886 de chancourtois was the first to arrange the chemical elements in order of atomic weights.
De chancourtois periodic table in 1862, before newlands announced his law of octaves and mendeleev described his periodic system, de chancourtois presented a paper to the french academy of sciences which was then published in this society own journal, comptes rendus however, the concept was poorly presented and difficult to understand.
Alexandre-emile béguyer de chancourtois (1820 – 1886) january 20 is the birthday of alexandre-emile béguyer de chancourtois béguyer de chancourtois was a french geologist who was the first to organize the elements on a chart by increasing atomic weights.
Chancourtois' original formulation includes elements in their correct places, selected compounds and some elements in more than one place the helix was an important advance in that it introduced the concept of periodicity, but it was flawed. Oif a periodic table is regarded as an ordering of the chemical elements demonstrating the periodicity of chemical and physical properties, credit for the first periodic table (published in 1862) probably should be given to a french geologist, aebeguyer de chancourtois.

Alexandre-emile béguyer de chancourtois, a french geologist, was the first person to notice the periodicity of the elements—similar elements seem to occur at regular intervals when they are ordered by their atomic weights. Alexandre-emile béguyer de chancourtois he devised an early form of periodic table, which he called the telluric helix with the elements arranged in a spiral on a cylinder by order of increasing atomic weight, de chancourtois saw that elements with similar properties lined up vertically.
