Supermassive black holes (SMBHs) play key roles in galaxy and cluster
evolution. This is most clearly seen in the "fossil record" that is
imprinted in the gas rich atmospheres of early type galaxies, groups,
and clusters by powerful SMBH outbursts. I will discuss the outburst
history of M87 as chronicled in its radio and X-ray images and the
implications of these outbursts for heating gas rich environments. In
addition to discussing the outburst around M87, I will review the
high spectral energy resolution results on Perseus from Hitomi, and
the results of a galaxy survey that shows the effects of SMBH
feedback on early type galaxies and which suggests that, at very
early epochs, SMBH outbursts may have truncated star formation and
altered the "normal" evolution of the stellar component of galaxy
bulges. I conclude by describing future X-ray missions, including Lynx, whose
sub-arcsecond angular resolution, would allow us to study the
evolution of SMBHs and hot, X-ray emitting atmospheres from
high redshifts to the present.
