Unit 8. Famous chemists. (Назад на главную)
D. I. Mendeleyev, the great Russian chemist, was born in Siberia on February 8,
1834. When seven years old he went to gymnasium in Tobolsk. He studied very hard,
he especially liked mathematics, physics and history. At the age of 16 he entered the
Pedagogical Institute in St. Petersburg, physicomathematical department. He
graduated from the Ins-.itute in 1855 and began to teach chemistry at the
Technological Institute and then at the University In 1865 Mendeleyev was granted
the Doctor of Science degree for the thesis on the combination of alcohol with water.
This work was both of great theoretical and practical significance. Soon after that
D.I.Mendeleyev was appointed Professor of General Chemistry of St. Petersburg
Jniversity. Despite lectures and supervision of the laboratory, D. I. Mendeleyev
carried on great research work.
Mendeleyev's greatest discovery was the Period c Law. The Periodic Law suggested
by Mendeleyev stated that the properties of the elements were a periodic
function of their atomic masses. He presented this work to the Russian Chernical Society.
Mendeleyev's Periodic Law opened a new era in the history of chemistry.
Mendeleyev was interested in many branches of science, indeed there is hardly
any field of science that was not enriched by his contribution. His numerous works
dealt with many subjects: properties of liquids, theories of solutions, the development
of the gas law, the use of oil and many others,
D. I. Mendeleyev was a great patriot. He did everything for the development and
progress of his country.
D. I. Mendeleyev continued his research work to the very last day of his life. He died
The world is thankful to Mendeleyev for his great contribution to the world science.
At present there is hardly anybody who doesn't know this Russian scientist and his
Periodic Law. D I Mendeleyev did very much for his country, for the development of
the world science.
