The paper investigates Hildesheimer’s relationship to Judaism through the analysis of two main elements. The first one is the correspondence between the author and his parents who lived in Palestine/Israel: it started in the second half of the 1930s and stopped in 1962. The second one is the author’s radio speech Mein Judentum (1978); here, Hildesheimer’s attitude is complex, provocative and paradoxical. Judaism did not play a marginal role in the author’s life; he mainly felt it as Heimatlosigkeit, but also as a belonging to a community that was fated, and often imposed and determined by external pressure and antisemitism.
