Démonstration
du Théorème de Weierstrass fondée sur le calcul des
Probabilités,
Comm. Soc. Math. Kharkov 2.Series XIII No.1 (1912), 1-2.
This is Bernstein's famous paper where he presented a probabilistic proof
of the Weierstrass Theorem, and introduced what we today call Bernstein
polynomials. Note that his proof is somewhat "overinvolved". We nowadays
present this proof in a slightly more elegant form. This paper is
reprinted in Russian in Bernstein's collected works. Note that the bound volume
XIII of the journal carries the year 1913 even though the first few numbers
published separately each carry the year 1912.

meilleure approximation des fonctions continues par les polynômes de
degré donné, Mem. Cl. Sci. Acad. Roy. Belg.
4 (1912), 1-103. This paper was awarded a
prize by the Belgian
Academy of Science. This was as a consequence of his answer to a question
posed by de La Vallée Poussin. Bernstein proved that it is not
possible to approximate |x| in [-1,1] by a polynomial of
degree n with an approximation of order greater than 1/n. It
also contains the first form of what we call inverse theorems, Bernstein's
inequality and more.
