Globular clusters, the oldest surviving entities in the universe,
are pivotal for early galaxy formation and evolution.
The contents of these ancient objects are currently
not well understood because precision photometry has caused an
astonishing and fundamental change in our understanding of
Milky Way globular clusters. Namely they are no longer thought
to be coeval and chemically homogeneous. Study of clusters in
our galaxy and in the nearby Magellanic Clouds with spectroscopic
techniques reveals surprising results about their stars and origin,
and challenges our theoretical understanding.
