By using ground based sub-millimeter observations to followup Spitzer-selected galaxies, we have discovered a starburst dominated hyperluminous infrared galaxy. A mid-infrared spectrum obtained with Spitzer-IRS provides a redshift of z=1.325, which has been subsequently confirmed using both NIR spectroscopy at Keck, and sub-mm spectroscopy with IRAM and the CSO. By combining the Spitzer and ground based sub-mm data, we measure an integrated IR luminosity of 4 x 10^13 Lsun. This is the only such object found in the 9 square degree NDWFS survey, and hence is incredibly rare. The only other dusty galaxies this bright show strong evidence of AGN activity, but this source does not. One reason this object could be so bright is due to lensing, and indeed a foreground source spectroscopically confirmed at z=1.034 seems directly aligned with the target. However it is unlikely that the geometry of this galaxy-galaxy lensing system could support an amplification more than a factor of a few. Our IRAC images reveal very faint and red satellite systems near our target, hence another possibility is that the galaxy is so luminous because of merging induced star-formation activity. Morphology is the best way to discriminate between these hypotheses, and hence HST observations are essential since the scales on which the merging or lensing are occuring are much smaller than what can be resolved from the ground.
