The authors show how the use of operational tools allows the derivation of the orthogonality properties of several different families of Hermite polynomials such as, classical Hermite polynomials, Hermite-Kampé de Fériet polynomials (two-variable Hermite polynomials), Multi-variable and multi-index Hermite polynomials and higher order Hermite polynomials.
