One of the durable legacies of the Hubble Space Telescope in extragalactic astronomy is that, in the centers of massive galaxies, dark compact objects (which are presumably supermassive black holes) are common. As examples, I discuss my analyses of the dynamics of the nuclear gas disk in M84 (a massive elliptical galaxy in the Virgo Cluster that contains a nuclear radio source) and of the stellar dynamics in M81 (which also exhibits signs of nuclear activity). Next, I briefly summarize the current census of nearby supermassive black holes, most of which have been discovered or verified from HST data (although important contributions have resulted from optical ground-based observations and data from the VLBA). This census led to the remarkable discovery this past summer that the mass of the central black hole is correlated with the shape of the gravitational potential of the galaxy's spheroid component. Two implications of this remarkable correlation concerning galaxy formation and evolution are discussed. Black hole searches in galaxies exhibiting low luminosity active galactic nuclei (such as M84 and M81) are important for understanding how matter can be accreted by a supermassive black hole and the energy generation mechanisms involved.
