he is a teacher and he devised the periodic table
Alexandre Beguyer de Chancourtois (1820-1886)
It was Lavoisier who wrote the first extensive list of elements - containing 33 elements. He distinguished between metals and non-metals, dividing the few elements known in the 1700's into four classes.
Dechancourtois is credited with the first published version of the periodic table in 1862, where he arranged the elements in a spiral format based on atomic weights. His work laid the foundation for the modern periodic table by demonstrating the periodicity of elements.
Antoine Lavoisier is often called the "father of modern chemistry" for his systematic approach to chemical nomenclature and for identifying and classifying elements, defining them as fundamental substances that cannot be broken down further. John Dalton contributed to the understanding of elements through his atomic theory, which proposed that each element is made up of unique atoms with specific weights. Meanwhile, Alexandre de Chancourtois created the first periodic table by arranging elements based on their atomic weights in a helical format, highlighting periodicity in their properties. Together, these scientists laid the groundwork for the modern understanding of elements and the periodic table.
Several chemists who contributed during the time were Lavoisier, Dobereiner, Newlands,Dumas, Gmelin, Chancourtois, Lothar Meyer, Odling, Mendeleev, Moseley, Seaborg, etc.
Alexandre-Emile Béguyer de Chancourtois was born in 1820.
Alexandre-Emile Béguyer de Chancourtois died in 1886.

A precursor of the modern perodic table was Alexandre Emolie Beguyer de Chancourtois, in 1862.
