If one tries to analyze the quality of and educational thinker by his originality and ability to foresee future needs then we can admit that Dmitry Ivanovich Mendeleev (1834-1907) was not only a great scientist but also a great educator as well. He left us many gifts – numerous articles on important educational issues that are still relevant also also many students who left memoirs about him. The founder of Russian physiology, Ivan Sechenov; a famous scientist in the field of agriculture, Kliment Timiryzev; as well as the founder of the noosphere or “realm of thought” concept, Vladimir Vernadsky are only a few of the many who would call Mendeleev their teacher.
