Dmitri Ivanovich Mendeleev
8 February 1834 – 2 February 1907
Dmitri Ivanovich Mendeleev was a Russian chemist and inventor. He is best remembered for formulating the Periodic Law and creating a farsighted version of the periodic table of elements. He used the Periodic Law not only to correct the then-accepted properties of some known elements, such as the valence and atomic weight of uranium, but also to predict the properties of eight elements that were yet to be discovered. Mendeleev was born in the village of Verkhnie Aremzyani, near Tobolsk in Siberia. In 1907, Mendeleev died at the age of 72 in Saint Petersburg from influenza.
Dmitri Mendeleev is often referred to as the Father of the Periodic Table. He called his table or matrix, “the Periodic System”
I saw in a dream a table where all elements fell into place as required. Awakening, I immediately wrote it down on a piece of paper, only in one place did a correction later seem necessary.Mendeleev, as quoted by Inostrantzev
