Comprehensive near-infrared, far-infrared, and CO measurements of the Sharpless 156 region reveal five distinct sources embedded in a giant molecular cloud. These embedded sources, which appear to have formed independently within the cloud, form a diverse collection of objects; these include a prestellar condensation, massive stars with associated reflection and emission nebulosity, a bright compact H II region, and possibly even a luminous, post-main-sequence M star. The majority of the cloud has been mapped in (C-12)O and (C-13)O and has been surveyed at 2.2 microns. Also presented are 40-160 micron far-infrared maps and 1-20 micron near-infrared photometry of the active regions along with 6 arcsec resolution 10 micron and 20 micron maps of the central nebula. Inquiry is made into the nature of each source and into the process of star formation for the complex as a whole.
