No less important, and another one of Gottfried Hoogen's visionary imports, was the black, Polish-bred Trakehner Patron. The stallion, who turned over 30 years old and sire more registered daughters in the Trakehner breed than any other stallion, is the sire of Mackensen, and also of the elite stallion Sokrates, whose success story is tightly connected to his home stud, the Klosterhof-Medingen in Lower-Saxony. For the Rhineland, it was Patron's excellent son Pasternak who proved to be of great quality. Ehrentusch has already been mentioned, but Pasternak also produced the approved Prinz Muthagen and a number of outstanding brood mares, who in turn became dams of influential sires.
