Dmitri Ivanovich Mendeleev was a Russian chemist and inventor who developed the periodic classification of the elements. He is often regarded as the father of the Periodic Table.

Mendeleev was born on 8th February in the small Siberian town of Tobolsk to Ivan Pavlovich Mendeleev, a teacher at the local gymnasium, and Mariya Dmitriyevna Kornileva. Today on 6th March in the year 1869, Dmitri Mendeleev presents the first periodic table to the Russian Chemical Society.

He formulated the Periodic Law and is often credited for rightly correcting the already existing periodic table of elements and also for predicting the properties of eight elements yet to be discovered. Mendeleev found that, when all the known chemical elements were arranged in order of increasing atomic weight, the resulting table displayed a recurring pattern, or periodicity, of properties within groups of elements.

Dmitri Mendeleev is honored on many commemorative stamps, coins, and miniature sheets. One such miniature sheet was released in 2009 to commemorate the 175th Birth Anniversary of Mendeleev. This sheet depicts Mendeleev’s portrait in the foreground and the periodic table in the background.
