Extragalactic sub-millimeter sources (often referred to as "SCUBA galaxies") represent an ultraluminous population that may account for the bulk of star formation at high redshift. Yet little is known about these galaxies because they are so difficult to study -- or even detect -- at optical and NIR bands. Early observations with IRAC detected SCUBA galaxies with remarkable ease. This was the first detection of light from the evolved stellar component of SCUBA sources, which are presumably dusty galaxies at high redshifts. We here propose IRAC observations of five fields with excellent SCUBA data including 32 sources. The IRAC measurements will determine the basic physical parameters of these galaxies, such as position, redshift, and luminosity of the normal stellar populations. These parameters will establish the evolution of SCUBA galaxies and are a necessary step in determining the star formation history of the early Universe. This study will represent a huge advance in both numbers of galaxies and knowledge of their properties.
