I set out to understand how memorial site educators conceptualize Holocaust education and how notions of history, memory, and place shape their ideas. I explored the teachings of four veteran memorial site educators at a site of memory of the Holocaust in Germany. The analysis was grounded in theories of collective memory broadly (Assmann, 2010; Halbwachs, 1992), German collective memory around the Holocaust (Confino, 2006; Frei, 1996; Fox, 1999; Kansteiner, 2006; Rothberg, 2022), memory and place (Marcuse, 2009; Young 1993), memorial site pedagogy (Konczyk, 2012), and multidirectional memory (Rothberg, 2009). I hoped to understand site educators' practice, as they both embody and create Holocaust memory narratives. I utilized a case study methodology (Stake, 1995; Yin, 2009) to understand the teaching of the Holocaust at a singular site in depth, considering how participants' everyday practices shaped teaching and learning there. I conducted semi-structured interviews, engaged in participant observations of tours and workshops, and gathered curricular materials and secondary sources. The educational offerings at the site and the site educators' perspectives became the organizational focus of the data. My findings revealed that site educators are "mediators of memory" who engage in a process of teaching through which context, curiosity, and complexity guide their practice. Their mediation is about centering people in the history, memory, and places of the Holocaust, creating opportunities to interact with the locale, which allows for multifaceted engagements. Site educators working as mediators of memory participate in the construction of a collective memory that aims for personalized experience for students. However, this individual journey leaves out opportunities to form a collective, diverse understanding of what it means to be German. Analyzing the practice and perspectives of memorial site educators provides insights into the choices they make and the agency they foster and create in the context of German collective memory. Looking at who is teaching the Holocaust and how at Holocaust memorial sites provides understanding into how a new generation of Germans are being taught to grapple with Germany's Nazi past.
