In Bernstein's proof of the Weierstrass Approximation Theorem, the polynomials

are constructed in correspondence with a function fC [0, 1] and are shown to converge uniformly to f. These Bernstein polynomials have been the starting point of many investigations, and a number of generalizations of them have appeared. It is our purpose here to consider several generalizations in the form of infinite series and to establish some of their properties.
