Dmitrii Mendeleev
Russian Chemist
Mendeleev's mother, Maria, who made it nearly her last task in life to bring Dmitrii to St. Petersburg to begin his university education 

Contribution to the Development of the Atomic Concept
Mendeleev's greatest accomplishment was his statement of the periodic law and the development of the periodic table.  In 1869 he gave a paper to the Russian Chemical Society in which he organized the 60 elements known at that time by increasing values of atomic weight and accounting for the known differences in their valences.  He left gaps in his table for then unknown elements.  Using these gaps, he predicted the existence of eka-boron, eka-aluminum, and eka-silicon, among others.  Within 10-15 years these elements were discovered and characterized, verifying his periodic law and his predictions.

Some Scientific/Historical Traveling Sites
Apartment where Mendeleev lived and worked during the time he was a professor at the university (1866- 1890); established in 1911, the museum includes his study restored to its original condition on the basis of old photographs.  Many illustrations and objects related to his life and scientific activity.
