dc.description.abstract	Bulge stellar velocity dispersions, sigma, in Seyfert 1 galaxies are combined with the M_bh -- sigma relation to validate reverberation mapping as a means of determining nuclear black hole masses. Seyfert galaxies follow the same relation as non-active galaxies, indicating that reverberation mapping is consistent with other methods. A similar result is obtained using new high resolution profiles of the [OIII] 5007 line for PG Quasars. Reconsidering the M_bulge - M_bh relation, we attempt to explain differences between Seyfert and non-active galaxies. We suggest that Seyfert bulges are systematically brighter than non-active galaxies, having lower M/L and younger stellar populations.	en
