A Brief History of the Periodic Table
In 1817, Johann Dobereiner noticed that there were patterns in the atomic weights and elements that possessed similar properties. The first attempt at designing a periodic table was published in 1862 by a french geologist, A.E. Beguyer de Chancourtois. He was the first to recognize that elemental properties reoccur every seven elements; unfortunately his chart had mistakes (included ions and compounds).
In 1863, John Newlands, who was an English chemist, wrote a paper that classified the 56 established elements into 11 groups based on similar physical properties. Newlands proposed the Law of Octaves in 1864, which stated that any given element will exhibit similar behaviors to a certain extent to the eight element following it.
Dmitri Mendeleer is considered to be the "Father of the Periodic Table". While Dmitri was working on his periodic table in Russia, at the same time in Germany Lothar Meyer was also working independently on the periodic table. Dmitri published his work in 1869, which was just a year before Meyer (1870).
