Dmitri lvanovich Mendeléev was born in Tobolsk in Western Siberia, Russia on 8 February 1834. After his early education, Mendeléev could join a university only due to the efforts of his mother.
Dedicating his investigations to his mother he wrote, “She instructed with example, corrected with love and travelled with me to places spending her last resources and strength. She knew that with the aid of science without violence, with love but firmness, all superstitions, untruth and errors can be removed.”
The arrangement of elements he proposed is called Mendeléev’s Periodic Table. The Periodic Table proved to be the unifying principle in Chemistry. It was the motivation for the discovery of some new elements.
He formulated the Periodic Law, created a farsighted version of the periodic table of elements, and used it to correct the properties of some already discovered elements and also to predict the properties of eight elements yet to be discovered.
The crater Mendeleev on the Moon, as well as element number 101, the radioactive mendelevium, are named after him.
