The problem of understanding black holes as quantum-mechanical objects, although presumably academic for the foreseeable future, has attracted great attention recently among theoretical physicists, due primarily to a fundamental conceptual tension. The thermodynamic properties of macroscopic black holes are widely believed to be universal; that is, essentially independent of any details of the microscopic theory in which gravity is embedded. This belief is based on their remarkably simple derivation l Research supported in part by Danish National Science Foundation.

N2 - After emphasizing the importance of obtaining a space-time understanding of black hole entropy, we further elaborate our program to identify the degrees of freedom of black holes with classical space-time degrees of freedom. The Cvetič-Youm dyonic black holes are discussed in some detail as an example. In this example hair degrees of freedom transforming as an effective string can be identified explicitly. We discuss issues concerning charge quantization, identification of winding, and tension renormalization that arise in counting the associated degrees of freedom. The possibility of other forms of hair in this example, and the prospects for making contact with D-brane ideas, are briefly considered.
