p { margin-bottom: 0.25cm; line-height: 120%; }Massive elliptical galaxies exhibit the most massive black holes, most extreme stellar initial mass functions, and most dramatic size evolution over cosmic time. Yet, their complex formation histories remain obscure. I will describe the ongoing MASSIVE Survey, a volume-limited, multi-wavelength, spectroscopic and photometric survey of the structure and dynamics of the 100 most massive early-type galaxies within 100 Mpc. A combination of integral-field spectroscopy on sub-arcsecond and large scales enables us to perform simultaneous dynamical modeling of the supermassive black holes, stars, and dark matter. I will also highlight properties of other mass components -- cold, warm, and hot gas -- from our multi-wavelength datasets. I will discuss the implications of these galaxies for ongoing black hole studies such as the Event Horizon Telescope and the pulsar timing array experiments searching for gravitational radiation.
