Look up De Chancourtois.
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.
Alexandre Beguyer de Chancourtois (1820-1886)
He proposed the wave-particle duality for the electrons.
Several chemists who contributed during the time were Lavoisier, Dobereiner, Newlands,Dumas, Gmelin, Chancourtois, Lothar Meyer, Odling, Mendeleev, Moseley, Seaborg, etc.

English chemist John Newlands also attempted to classify the known elements of his day based on their atomic weight. Like de Chancourtois, he noticed a repeating pattern-every eighth element had similar properties.
