Dmitri Mendeleev
Dmitri Ivanovich Mendeleev; 8 February 1834 – 2 February 1907 O.S. 27 January 1834 – 20 January 1907) was a Russian chemist and inventor. He formulated the Periodic Law, created a farsighted version of the periodic table of elements, and used it to correct the properties of some already discovered elements and also to predict the properties of eight elements yet to be discovered...

Dmitri Mendeleev quotes about
Work, look for peace and calm in work: You will find it nowhere else. Pleasures flit by -- they are only for yourself; work leaves a mark of long-lasting joy, work is for others.
Work, look for peace and calm in work: you will find it nowhere else.
I saw in a dream a table where all the elements fell into place as required. Awakening, I immediately wrote it down on a piece of paper.
The establishment of a law, moreover, does not take place when the first thought of it takes form, or even when its significance is recognised, but only when it has been confirmed by the results of the experiment.
There is nothing in this world that I fear to say.
We must expect the discovery of many as yet unknown elements-for example, elements analogous to aluminum and silicon- whose atomic weight would be between 65 and 75.
No one nor anything can silence me.
No law of nature, however general, has been established all at once; its recognition has always been preceded by many presentiments.
Certain characteristic properties of elements can be foretold from their atomic weights.
Knowing how contented, free, and joyful is life in the world of science, one fervently wishes that many would enter its portals.
Why do they [Americans] quarrel, why do they hate Negroes, Indians, even Germans, why do they not have science and poetry commensurate with themselves, why are there so many frauds and so much nonsense? I cannot soon give a solution to these questions ... It was clear that in the United States there was a development not of the best, but of the middle and worst sides of European civilization; the notorious general voting, the tendency to politics... all the same as in Europe. A new dawn is not to be seen on this side of the ocean.
There exists everywhere a medium in things, determined by equilibrium.
It is the function of science to discover the existence of a general reign of order in nature and to find the causes governing this order. And this refers in equal measure to the relations of man - social and political - and to the entire universe as a whole.
The magnitude of the atomic weight determines the character of the element, just as the magnitude of the molecule determines the character of a compound body.
