Recent, deep X-ray observations have provided profound insights into the intrinsic properties of AGNs at all observable redshifts. However, it is becoming increasingly clear that the complete understanding of these cosmologically important objects will only be achieved when we can comprehend their energy output at all observable wavelengths. In this talk I will focus on how X-ray and infrared observations can be used in a complementary manner to paint a more complete picture of AGNs in their host environments (i.e., from accretion disks and dusty tori to their host galaxies). To demonstrate this, I will present the results from my recent infrared study of high redshift X-ray identified AGNs, which shows tentative evidence of higher dust covering factors and/or increased levels of star formation around AGNs in the distant universe (i.e., z=1-2).
