Abstract
Employing the relationship between the black-hole thermodynamic functi ons and the Euclidean path-integral approach to quantum gravity, we pr ove, in the framework of four-dimensional Einstein gravity, that the e ntropy of a stationary black-hole with a bifurcating Killing horizon s urrounded by arbitrary classical matter fields is one quarter of the a rea of the event horizon independent of the matter fields involved.
