We present a quantitative morphological study of high redshift galaxies using data from a complete NICMOS imaging survey of the Hubble Deep Field North. The NICMOS H(1.6mu ) and J(1.1mu ) images sample rest frame optical wavelengths for galaxies with z < 2.5. The high angular resolution of the NICMOS images allows us to directly compare quantitative morphological parameters of high redshift galaxies with those of nearby galaxies observed at similar rest-frame wavelengths. We classify the NICMOS-HDF galaxies to a limiting magnitude of I ~ 27 using asymmetry and rest-frame color. We also present methods for directly comparing asymmetries measured from the NICMOS images with those determined for a sample of ground-based images of nearby galaxies which span all morphological types. We analyze the asymmetries of HDF galaxies as a function of wavelength, comparing the optical WFPC2 to the near-IR NICMOS images. We find that a large fraction of galaxies with peculiar WFPC2 morphologies remain asymmetric in the near-infrared NICMOS data. This suggests that the asymmetries are not simply the consequence of observing irregularly distributed star formation at blue/UV wavelengths, but instead reflect the truly irregular structural state of these galaxies, perhaps due to galaxy interactions or mergers.
