A Census of Massive Stars Across the Hertzsprung-Russell Diagram of
  Nearby Galaxies: What We Know and What We Don't
  When we look at a nearby galaxy, we see a mixture of foreground stars and
bona fide extragalactic stars.
  I will describe what we need to do to get meaningful statistics on the
massive star populations across the H-R diagram. Such a census provides the
means of a very powerful test of massive star evolutionary theory.
