Abstract

I will talk about how resolved stellar populations can and have been used to study the fossil record of star formation in nearby Local Group galaxies. This requires accurate colours, variability, chemistry and kinematic measurements of large samples of individual stars from deep imaging and spectroscopy. These studies provide a detailed picture of galaxy evolution going back to the earliest times, providing insights into the initial star forming properties of the early Universe, and how these may have changed over time.
