Lineage Map
The Great Book — Sonnemann
Introduction
There are lineages whose name, rather than scattering into a multitude of branches and generations, concentrates almost entirely in the brilliance of a work. The Sonnemann lineage belongs to this singular type: born in the modest piety of a Franconian town, it rises, in the space of two generations, to the heights of the German public sphere, before the tragic history of the twentieth century disperses it through exile and brutally closes the great chapter it had opened.
This family of Jewish merchants and bankers from Bavaria and then Frankfurt am Main embodies, in its own way, one of the most characteristic destinies of German Judaism in the long nineteenth century: that of the passage from emancipation to integration, from the counting house to the tribune, from the synagogue to the forum of opinion. In it we read the aspiration to make culture, justice and public debate so many secular extensions of a moral imperative inherited from tradition. This work retraces this journey by distinguishing, at each stage, what the archive establishes from what Memory transmits, for honesty toward a lineage begins with respect for what it truly allows us to know.
