HST observations show that the surface brightness profiles of
early-type galaxies have central cusps. I summarize here the results
of van der Marel (1999), which show that
the observed characteristics of these cusps are consistent with the
hypothesis that all early-type galaxies have central black holes (BHs)
that grew adiabatically in homogeneous isothermal cores. The models
suggest a roughly linear correlation between BH mass and V-band galaxy
luminosity, log M_BH = -1.83 + log L in solar units, similar to the
relation suggested by kinematical BH detections in nearby galaxies.
