Massive elliptical galaxies exhibit the most massive black holes and the most dramatic size evolution over cosmic time. Yet, their complex assembly 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 and discuss the implications of our black hole findings for the Event Horizon Telescope and pulsar timing array searches for gravitational waves.
