Mendeleyev, D. Ivanovich


Russian chemist who introduced the periodic classification of the elements.

Mendeleyev taught chemistry at St. Petersburg University, where he discovered the periodicity of the chemical properties of the elements.

The periodic table became one of the most useful and important generalizations of chemistry and of all science. In Mendeleyev's lifetime several new elements, including gallium, scandium, and germanium, were found in nature, and their chemical behavior matched that predicted by Mendeleyev's periodic table.

He also made contribution in the fields of hydrodynamics, meteorology, geology, and he investigated the technology of explosives, petroleum, and fuels.
