Abstract:   I will present and review recent results on 3 topics on the use of AGN to constrain the properties of their central black holes. 1) How do black holes work- I will discuss recent results on the broad band spectra of AGN which allow the first set of accurate determinations of the bolometric luminosity in these objects and on the shape of the broad band 0.1-200 keV X-ray spectra, which will shed light on the nature of reprocessing in Seyfert galaxies 2) How do AGN evolve: recent results optical and x-ray surveys which constrain the evolution of AGN to z~4, 3) Results from the first large unbiased sample of AGN which examines the properties of the host galaxies and whether the central AGN is related to the fundamental galaxy properties.
