  We propose and study the properties of a set of polynomials $M_{n\alpha, H\
}^{s}(z)$, $C_{n\alpha, H}^{s}(z)$ $W_{n\alpha, H}^{s}(z)$ with $n,s\in N$
$;\alpha =\pm 1;$and where $H$ stands for Hermite ; the ''root '' polynomial
>.These polynomials are obtained from a deformation of Hermite polynomials
$H_{n}(z).$The structure underlying the deformation seems quite general and not
only restricted to Hermite polynomials.
