We describe a program of astrometric measurements (positions and proper motions) on crowded star fields in the cores of globular clusters and in the nucleii of several nearby galaxies which we propose to carry out with the Space Interferometry Mission. These observations will permit accurate values and limits to be placed on the masses of the black holes which are thought to be lurking in these regions of enormously high stellar density. The science can be accomplished even if an imaging capability with a full and complete set of baselines cannot be provided with SIM.
