Abstract: One major goal of quasar research is to understand how they fit into the 
larger context of SMBH growth and star formation in young (high redshift) galaxies. 
Our group has focussed on metallicity measures, which indicate that quasars at all 
redshifts were preceded by substantial star formation - enough to enrich the gas to 
near or above solar levels. Other studies have reached similar conclusions. The 
emerging picture is that quasar hosts are massive galaxies - old, red and dormant 
today, their main episodes of star formation and SMBH growth occurred long ago, 
roughly during the quasar epoch. I will briefly review some recent results and the 
prospects for future work.
