This article is the editorial introduction to the special issue of the European Journal of Criminal Policy and Research Compassionate Criminology: The Legacy of Josine Junger-Tas (1929–2011). The article consists of four parts and an Appendix (i.e., the bibliography of her publications). In the first section, we provide a brief overview of the highlights of her professional career of 40-plus years, including her contributions to the institutionalization of European criminology. The second section discusses how her focus on comparative criminology and policy relevance run as a red thread through her work as a criminologist. The third part centers around Junger-Tas’s consistent concern with the responsibility of scholars and researchers to “do the right thing” and to speak out for the most vulnerable parts of the population (youth in particular). We believe that as a public criminologist avant la lettre Junger-Tas’s main heritage lies in drawing the contours of what may be called evidence-based compassionate criminology. The fourth section provides a brief introduction to the seven articles in this special issue.
