Dmitry Mendeleev

Dmitry Mendeleev (1834-1907) was a brilliant Russian scientist and public figure. He is widely known as a chemist, physicist, economist, metrologist, technologist, geologist, meteorologist, teacher, and aeronaut.

In 1869, Mendeleev published his periodic table of elements in the journal of the Russian Chemical Society and in 1871 he finally formed his ideas into the periodic law. The value of his discoveries was that he corrected the then-accepted properties of some known elements (such as uranium), as well as predicted the properties of three elements that were yet to be discovered (germanium, gallium and scandium).
