Among the earliest witnesses of Bruno Schulz’s life known by Jerzy Ficowski were two lawyers from Drohobych, Michał Chajes and Izydor Friedman (after the war Tadeusz Lubowiecki).

The reason lies deep in the realm of genre conventions of Regions, conditioned by literary culture of Ficowski who, formed in the circle of the nineteenth-century.
