SUMMARY:Evolution of Galaxy Populations in the Most Distant Galaxy Clu
 sters\, Astronomy Colloquium\, Mark Brodwin\, University of Missouri- 
 Kansas City
DESCRIPTION:I will describe the emerging evidence for an epoch of sign
 ificant growth of cluster galaxies at z ~ 1.5\, about 10 billion years
  in the past.  This evidence rules out the (overly) simplistic galaxy 
 formation models that seem to fit the data at later times (ie. at z < 
 1).  New measurements of rapid evolution in a number of critical probe
 s of the growth of cluster galaxies aEuro" including a census of their
  stars\, the colors of those stars\, and the rates of star formation\,
  mergers and black hole activity aEuro" all suggest the z ~ 1.5 era is
  a very active one in the formation and assembly of massive cluster ga
 laxies.
