WISE has recently completed the first all-sky infrared survey since IRAS, pushing hundreds of times deeper. This enables the search for the most extreme galaxies over fields that are hundreds of times wider than were available using the Spitzer surveys. The details of the processes in these galaxies - intense star-formation activity, the growth and fueling of AGNs, the buildup of stellar mass, and the astrophysics of their interstellar medium (ISM) - have been investigated using galaxies selected by WISE colors. The resulting sample has been targetted using large ground-based telescopes, and are approved for observations using the Herschel Space Observatory in GO-1. Herschel will yield reliable measurements of their total infrared luminosity. The targets are typically distant, ultraluminous galaxies (ULIRGs) at redshifts z~2-3. Herschel (and soon ALMA) will reveal the cooler components of their ISM; however, the transition betwen hot dust near an AGN and the stellar population of these galaxies is relatively poorly constrained from the WISE data alone, owing to very red colors from 3-22 microns. Spitzer can probe much deeper in modest exposure times, and address this important question for the astrophysics of these sources, which cannot be attacked otherwise until JWST is operating. We propose imaging of 54 WISE-selected targets that are queued for Herschel observations. 45 of these are entered in our Cycle-7 snapshot Spitzer program, and we observe any that remain unobserved by the end of Cycle-7 in Cycle-8. Nine additional Herschel targets - selected using the same criteria since the Spitzer Cycle-7 program was accepted - are also included, to ensure that the coverage and quality of the full Herschel dataset is well matched by Spitzer observations.
