DESCRIPTION:Supermassive black holes are believed to grow during bright AG
 N phases and are considered key players in the formation and evolution of 
 galaxies.  Black hole masses are thus fundamental physical quantities to c
 haracterise AGN activity and host galaxies.  In this talk I will briefly r
 eview the accuracy and reliability of black holes mass measurements from z
 ero to high redshift and present new results on virial estimators\, curren
 tly the only way to measure black hole masses beyond the local universe.  
 I will then discuss the redshift evolution of the scaling relations betwee
 n BHs and their host galaxies\, as derived from the application of these v
 irial estimators\, and the constraints we can infer for galaxy evolutionar
 y models.\n
