We propose new Spitzer observations that will establish the infrared properties of a complete sample of Seyfert galaxies in the nearby Universe. Our sample, which includes all known B < 13.0 Seyferts in the Revised Shapley-Ames catalog, reduces biases found in other samples selected at optical/X-ray/IR wavelengths against type 2 and low-luminosity nuclei, and against AGN in edge-on host galaxies. These new observations, combined with existing archival data, will complete IRS low resolution, MIPS imaging at 24 microns, and IRAC imaging for the nuclei of the 91 Seyferts in the sample. With this data set, we will quantify on a firm statistical basis the differences between the infrared properties of type 1 and type 2 AGNs. We will also constrain the nature of the dust surrounding the central engine and identify trends as a function of luminosity and star-forming activity. The majority of these galaxy nuclei are also detected by Chandra or XMM Newton, and we plan to propose to get images of the remainder. Together with the existing optical data, it will be possible to extend this study across the electromagnetic spectrum. The sample lets us study the Seyfert phenomenon where it can best be studied - in the nearby Universe.
