Dmitri lvanovich Mendeléev (1834-1907)
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.
