The legacy of the experimental hadron physics programme at COSY

Abstract

The experimental hadronic physics programme at the COoler SYnchrotron of the Forschungszentrum Juelich terminated at the end of 2014. After describing the accelerator and the associated facilities, a review is presented of the major achievements in the field realized over the twenty years of intense research activity.
