The Hubble Deep Field (HDF) is the deepest set of multicolor opticalphotometric observations ever undertaken, and offers a valuable data set withwhich to study galaxy evolution. Combining the optical WFPC2 data withground-based near-infrared photometry, we derive photometrically estimatedredshifts for HDF galaxies with J<23.5. We demonstrate that incorporating thenear-infrared data reduces the uncertainty in the estimated redshifts byapproximately 40% and is required to remove systematic uncertainties within theredshift range 1 2, andbridge the redshift gap between those two samples. The overall star formationor metal enrichment rate history is consistent with the predictions of Pei andFall (1995) based on the evolving HI content of Lyman-alpha QSO absorption linesystems.Comment: Latex format, 10 pages, 3 postscript figures.
