We report on Hobby-Eberly Telescope and Palomar 5 m spectroscopy of recently identified gamma-ray blazars in the Fermi LAT Bright Source List. These data provide identifications for 10 newly discovered gamma-ray flat spectrum radio quasars and six new BL Lacertae (BL Lac) objects plus improved spectroscopy for six additional BL Lac objects. We substantially improve the identification completeness of the bright LAT blazars and give new redshifts and z constraints, new estimates of the black hole masses, and new measurements of the optical spectral energy distribution.
