Wlodimir (Vladimir) Ledochowski: the "Last of the Great Roman Generals of the Jesuits"

According to a book by Malachi Martin:

It was during the twenty-seven year Generalate of Father Wlodzimierz Ledochowski (1915-1942) that the traditional character of the Society received the firmest stamp and clearest definition since the Generalate of Claudio Acquaviva in the sixteenth and seventeenth centuries. One might even say that Ledochowski insisted on fidelity to the structure of Jesuit obedience, was an almost merciless disciplinarian,and maintained a stream of instructions flowing out to the whole Society about every detail of Jesuit life and Ignatian ideals. He know exactly what Jesuits should be according to the Society’s Constitutions and traditions; and under strong hands of two quite authoritarian Popes, Pius XI and Pius XII, he reestablished the close ties that had once linked papacy and Jesuit Generalate. Ledochowski, in fact, gave renewed meaning to that old Roman nickname of the Jesuit Father General, “the Black Pope. Just as Pius XII can be described as the last of the great Roman Popes, so Ledochowski can be called the last of the great Roman Generals of the Jesuits.
