In accordance with its expanded responsibilities, the institute is now known as the "Institut für Kernenergetik und Energiesysteme" (IKE). Höcker’s 80th birthday, his role as founder and leader in the IKE, and the 40th anniversary of the IKE were celebrated by a "Festkolloquium" in 1996. The following reports were published in "Kernphysikalische Forschungsberichte" ("Research Reports in Nuclear Physics"), an internal publication of the German "Uranverein". The reports were classified Top Secret, they had very limited distribution, and the authors were not allowed to keep copies. The reports were confiscated under the Allied Operation Alsos and sent to the United States Atomic Energy Commission for evaluation. In 1971, the reports were declassified and returned to Germany. The reports are available at the Karlsruhe Nuclear Research Center and the American Institute of Physics. Poloniae Annalibus  Poloniae Annalibus (July 16, 1953) is an apostolic letter of Pope Pius XII commemorating the seven hundredth anniversary of the canonization of Saint Stanislaw and encouraging the Polish episcopate to be united and strong in face of persecution. According to the letter, Saint Stanislaw was an exemplar of steadfastness in his time and a model for our time. As bishop of Krakow, he was a model for piety, social engagement and courage. He dared to tell King Boleslaw his faults and sin in his face. He was tortured as a result but his mind did not bend. The Krakow faithful were so enraged over this sacrilege, that they forced the king to abdicate. He went into exile for the rest of his life. The bishops of Poland display the same fervour and the same love as the faithful in those days. Indeed, their trials are very comparable to those of Saint Stanislaw. A night of terror has descended over faithful Poland. But in the darkness of night shine the stars of Polish loyalty in such a way, that the whole world watches in admiration. Many Poles lost everything, because they defended their faith. Many lost their lives. Many bishops, priests and Religious were incarcerated, sent to Siberia, robbed of all rights, tortured, maligned and falsely accused of all things, for one reason only: They were messengers of Christ. Average and dispirited persons cannot understand this, but eternal honour is certain all those, who gave everything.
