The Life of Dmitry Ivanovich Mendeleyev.

Dmitry Ivanovich Mendeleyev (sometimes spelled 'Mendeleev') is one of the greatest Russian chemists to have ever lived. One of his many accomplishments was devising a way to organize the known elements by showing that they exhibit a periodicity, or regular pattern, of properties when they are arranged according to their atomic weights. This meant that he could predict the properties of the next elements before they were discovered. Other investigations of his include the study of the chemical theory of solution, the thermal expansion of liquids, the nature of petroleum, and others.
