Updated analysis techniques and recalibrated archival monitoring data for the Seyfert 1 galaxy NGC 3783 indicates the presence of a supermassive black hole in this galaxy. Using UV data from the International Ultraviolet Explorer satellite and ground-based optical spectra, we have measured more precise emission line reverberation in response to continuum variations. The stratification of the broad line region (BLR) suggested by our results, combined with estimates of the line velocity widths, is consistent with a gravitationally-dominated BLR and allows us to derive a mass for the central black hole.
