Famous people, Russia Mendeleev
Dimitri Ivanovich Mendeleev, the youngest of fourteen children, was born in Tobolsk, Sibiria, on 7th February, 1834. His father died when Dimitri was quite young and his mother ran a glass-making factory to support her large family.
Mendeleev studied Chemistry at the University of St Petersburg and graduated in 1856. In 1859 he was sent to study at the University of Heidelberg. In 1863 Mendeleyev returned to St Petersburg, he became Professor of Chemistry at the Technical Institute and soon Professor of General Chemistry at the University of St Petersburg. Mendeleev was a renowned teacher and, because no good textbook in chemistry was available, he wrote the two-volume Principles of Chemistry which became a classic. Mendeleev is best known for his work on the periodic table of the properties of the chemical elements. He predicted the existence and properties of new elements. In 1890 he resigned from the university and he became director of the Bureau of Weights and Measures in St Petersburg in 1893. He held this position until his death from pneumonia on 20th January, 1907.
His daughter from his second marriage, Lyubov, became the wife of the famous Russian poet Alexander Blok. His other children were son Vladimir and daughter Olga, from his first marriage, and son Ivan and a pair of twins from his second marriage.
