Twenty years after the two rabbis, Emil Lehmann, a great-great-great-grandson of Berend Lehmann's and a Dresden liberal lawyer and politician, wrote an essay about him, which for the first time used archival evidence. He pointed out the adroitness of his ancestor in the tactics of his fighting, also admiring the foresight with which the Resident had seen to the long-time functioning of his foundations. Though more realistic as a biographer than his predecessors, Emil Lehmann still had the bias of an admiring descendant.
