It is known as the chemist, physicist, economist, technologist, geologist, meteorologist, teacher, aeronaut. In 1869, working over «Chemistry Bases», he has opened one of fundamental laws of nature ? the periodic law of chemical elements.

Souvenir sheet represents: reference scales of firm “Nemets” of 1895, on which D.I.Mendeleev conducted exact weighings at renewal of standard of mass - pound (1895 - 1898) and nodule rock crystal from collection of minerals of Dmitry Ivanovich.

This stamp was issued on the 6-th of February and yet isn't available in my city. I'm looking forward for it since  D. Mendeleev is one of our great world known scientist. I will be glad to have this stamp in my collection.
