Abstract
The combinatorial properties of the bell numbers are shown to follow from t he algebraic properties of the boson operators in an extremely simple way. This treatment sheds further light on the 'hidden' combinatorial significan ce of the boson operators and of the identities they satisfy, and allows a consistent introduction of q-deformations.
