Description

I will talk about our current understanding of globular cluster (GC) formation and what we have yet to learn about them. I will particularly focus on the chemical and dynamical properties of the neglected GC NGC4372, which I studied for the first time with  high-resolution spectroscopic observations.
Its chemical abundances revealed it as a typical representative of the old, metal-poor halo group. More interesting, however, are its structural and kinematic properties as the cluster has an unusually high intrinsic rotation for its metallicity and appears to be rotationally flattened. I will discuss what
rotating GCs tell us about their early evolution.
