... We present preliminary results from two programs to image the host galaxies of radio-quiet quasars in 1.6 micron light using NICMOS camera 2 on HST. The high redshift program consists of QSOs covering the redshift range 0.8 < z < 4.4 and a range of QSO luminosities. Of the six objects for which data have been obtained the results range from no host galaxy detected, to an obvious galaxy with an interacting companion, to a possible high redshift galaxy cluster. ...
