I review electric-magnetic duality in four-dimensional N-extended supergravity and the mathematical structure which is hidden in these theories. Groups of type E(7) emerge in this context and their basic invariant structure is seen to be related to physical properties of extremal black holes such as entropy and angular momentum.
