Some facts about the life and career of Carl (Karl) Loog
Little is known about Carl Loog, who called himself Karl Loog until 1930. According to the edition-1916 of the Rangliste der höheren Reichs-Post- und Telegraphenbeamten, he was born in 1875. In 1895, in Kolberg, he began to work in telegraphy. In 1898, he passed his first examen for the job of Postpraktikant, a job he got in 1901. In 1905, he became Ober-Postpraktikant; in 1914 Inspektor. The Berliner Adressbuch shows that from 1916 to 1936, he lived in Berlin with short intervals. Between 1916 and 1931, he lived in the Berlinerstraße 10 (Berlin-Wilmersdorf); in 1934 and 1935, he lived in Berlin-Nikolassee (Von Lüdendorfstraße 32-34). Until 1920, he worked as a Telegraph Inspektor. In 1921, he became Telegraph Direktor was mentioned (this function is also mentioned on page 128 in Mysterien von Sonne und Seele [dr. H.-H. Kritzinger, Berlin, 1922, written in 1921]). In the issue of March 1, 1922 of the Verzeichnis der höheren Beamten der Reichs-Post und Telegraphenverwaltung, he was listed as a Postrat. Since this function was also mentioned in the article Prophezeiungen - Eine Erwiderung von Postrat C. Loog, published in the January issue of 1922 of the monthly Psychische Studien, one might conclude that Loog started to work as a Postrat by the end of 1921. In 1928, Loog started to work at the Reichspostzentralamt. In the issue of March 1942 of the Verzeichnis der höheren Beamten der Deutschen Reichspost - nach dem Stand vom 15. Februar 1942, the rank of Postrat was mentioned and the Reichspostzentralamt. The title page of the copy of Die Weissagungen des Nostradamus which is part of the collection Hitler Personal Library of the Brown University, Providence, Rhode Island, USA, contains the handwritten note Oberpostrat in telegr. technischen Reichspostministeriums Berlin.
On September 15, 1936, Loog retired. In 1938, he lived in Bad Schwartau; from 1939, he lived in Lunenburg. His name is still mentioned in the edition-1942 (February 15) of the Verzeichnis der höheren Beamten der Deutschen Reichspost, the last edition in World War II of this register, which might mean that Loog was alive in at least the beginning of 1942. In the Verzeichnis der höheren Beamten der Deutschen Bundespost (1956), the first post-war update of the Verzeichnis der höheren Beamten der Deutschen Reichspost, Loog's name is no longer mentioned. On the pages 158 and 159 of Nostradamus - der Prophet der Weltgeschichte (Berlin, 1953) dr. phil. Alexander Max Centgraf, using the pseudonym dr. N. Centurio, had written that Loog since a considerable time had taken the great secret of Nostradamus with him into his grave. Unfortunately, Centgraf did not mention the date of Loog's decease. This means that Loog died between 1942 and 1953. According to dr. Patrice Guinard, a French Century-scholar, Loog died in 1945, but he does not give the source of this information.
Two articles which Loog wrote about telegraphy are part of the collection of the Deutsche Nationalbibliothek: the 12 page-article Pufferbetrieb, published in Berlin in 1927 in Telegraphen- und Fernsprech-Technik and the 7-page article Die selbsttätige Regelung des Pufferbetriebes mittels Relais-Stufenschaltung, published in Berlin in 1931, also in Telegraphen- und Fernsprech-Technik
In Germany, three patents of Loog are registered. The earliest patent, dating from October 30, 1919 and registered as nr. 335608, is entitled Schaltung für die Stromversorgung von Mikrophonstromkreisen aus dem Starkstromnetz. This patent is also registered in France. A second patent, dating from April 26, 1929 and registered as nr. 504120, is entitled Schaltungsanordnung zur selbsttätigen Regelung des Ladestromes einer Batterie, insbesondere für Fernsprechstromversorgungsanlagen, mittels eines Differentialrelais, dessen Wicklungen in die Lade- und Entladeleitung geschaltet sind. This patent is also registered in Belgium and France. A third patent, dating from January 29, 1930 and registered as nr. 514898, with an addition, registered as nr. 543648, is entitled Schaltungsanordnung für die Stromversorgung von Fernsprechanlagen mit selbsttätiger Regelung des Pufferstromes. This patent is also registered in Belgium, England, France and The Netherlands. 


Loog-1921 (1920)Die Weissagungen des Nostradamus (1921 [1920])
On Nostradamus, Loog wrote one book
: Die Weissagugen des Nostradamus: erstmalige Auffindung des Chiffreschlüssels und Enthüllung der Prophezeiungen über Europas Zukunft und Frankreichs Glück und Niedergang, 1555-2200, using the C as the initial of his first name, as in the article, published in Psychische Studien. Die Weissagungen des Nostradamus was published in 1921 in Pfullingen in Württemberg by Johannes Baum publishers, a company which was specialized in publishing occult literature. In Die Weissagungen des Nostradamus, which was finished in the course of 1920, Loog had arranged a number of quatrains by means of a  key he derived from a number of Latin lines in the Letters which accompany the Centuries. Basing himself upon these quatrains, he made statements about the past, the present and the future of Europe until 2200. In Magische Kräfte - Geheimnisse der menschlichen Seele, dr. Hans-Hermann Kritzinger, in the 1920's a prominent person in the paranormal field, who in 1922 was the editor of Psychische Studien, wrote that it was during World War I that Loog derived the key from the Preface and the Epistle. In Das magische Quadrat des Nostradamus, Karl Drude, who after World War II elaborated Loog's ideas, quoted a remark by Loog which shows that he derived the key near the end of World War I.[1]  
Loog's aim of
Die Weissagungen des Nostradamus was, as can be read in the epilogue to its fourth edition, to (a) draw attention to the "peculiar phenomenon of clairvoyance", (b) to produce evidence of the existence of clairvoyance and (c) to draw the attention of his readers to things which he, in his hobbyist study of the Provençal seer, considered to be peculiar and interesting.
The source text which Loog used while writing Die Weissagungen des Nostradamus was Le Pelletier's Les Oracles de Michel de Nostredame (Paris, 1867). From this work, he copied a number of links, such as the link of quatrain 01-35 to the decease in 1559 of Henry II and the link of quatrain 09-20 to the arrest in 1791 of Louis XVI.

In 1921, Die Weissagungen des Nostradamus had five editions, in 1922 three more were published. In 1931, the price of the the eighth edition was 1.80 Mark. The first edition contained an epilogue, written by Johannes Baum publishers, in which was noted that on October 20, 1920, Loog confidentially handed over the key word he used. From the fourth edition, an epilogue was included, dating from October 1921, in which Loog explained some elements of his cipher key and defended himself against critics. In a more extensive version, this epilogue was published in the January issue of volume 1922 of the monthly Psychische Studien – Monatliche Zeitschrift vorzüglich der Untersuchung der wenig gekannten Phänomene des Seelenlebens gewidmet. It was entitled: Prophezeiungen - eine Erwiderung von Postrat C. Loog. This reply made clear that Loog addressed directing himself to notably count Carl Ludwig Friedrich Otto Von Klinckowstroem, whose criticism on his code key was published on the pages 580/585 of the October issue of volume 1921 of Psychische Studien, entitled Prophezeiungen - Eine kritische Betrachtung. Von Klinckowstroem had doubts about Loog's code key, a.o. because Loog, according to him, not only used the 942 genuine Century-quatrains when deriving the code key, but also the 27 "leftover-quatrains" which, according to Von Klinckowstroem, most likely were not genuine. In his reply, Loog emphasized that he only used the 942 genuine quatrains. In the January issue of volume 1922, Loog's reply was followed by Von Klinckowstroem's reaction it; he remained doubtful.


A review in 1922
In 1922, the Theosophisch-Okkulte Bücherschau published a review of Die Weissagungen des Nostradamus. A quote from this review shows that Loog's comment upon the Centuries in connection with Germany's situation after World War I gave him hope. According to the reviewer, Die Weissagungen des Nostradamus showed that the Frenchman Nostradamus had predicted the downfall of the League of Nations and the Versailles Treaty and the foundation of a Great-German empire. The quote also illustrates that in 1922, both in Germany and abroad, the contents of Die Weissagungen des Nostradamus were quite sensational.
The original text of this quote read as follows: 

Wie zu erwarten, hat Loogs neues Nostradamus-Werk in und außer Deutschland größtes Aufsehen erregt, denn es ist ja der Franzose, der u. a. den Bruch des Völkerbundes, die Vernichtung des Versailler Vertrages und den Aufstieg Groß-Deutschlands prophezeit.


A review in 1927
Von Klinckowstroem, who in 1921/22 in Psychische Studien discussed with Loog about Die Weissagungen des Nostradamus, discussed Die Weissagungen des Nostradamus once again in the section Originalarbeiten in volume II of the Zeitschrift für kritischen Okkultismus und Grenzfragen des Seelenlebens (p.97-104). And once again, Von Klinckowstroem was not convinced that Loog had found the key with which the Centuries could be deciphered. Von Klinckowstroem wrote that Loog unveiled some elements of his key, but not the key itself, which made it impossible for others to apply this key. He endorsed the critic of Johann Illig in Historische Prophezeiungen (Pfullingen in Württemberg, 1922, p. 68) that Loog had not been able to break through the gloomy nature of the Centuries. Closing, he noted that if Nostradamus while writing the Centuries used the key which Loog had derived from them, this would imply that the text of all quatrains as well as the text of the Preface to Cesar and the Epistle to Henry II had to have been conceived in 1555. This, according to Von Klinckowstroem, was not the case. The Epistle to Henry II was written on March 14, 1557, a date, mentioned in the first half of the Epistle. Various early editions of the Centuries had different contents. The 1850-Bareste-edition contained four centuries (century 04 running from quatrain 04-01 to 04-53). A 1590-Antwerp-edition however, which was supposed to be a reprint of a 1555-Avignon-edition, contained seven centuries (century 07 running from quatrain 07-01 to 07-35). The centuries 08, 09 and 10 were only available in editions which were printed in 1568 or later. In the eyes of Von Klinckowstroem, the value of Loog's key depended on the number of quatrains he had used. Von Klinckowstroem repeated his critic in Psychische Studien that Loog's key, because of a wrong number of quatrains, could not be used to decipher the Centuries.


Die Weisssagungen des Nostradamus as a proof of the clairvoyance of Nostradamus (1931)
In 1931, in the series Die okkulte Welt, published by the Johannes Baum Verlag in Pfullingen in Württemberg, volume 187 was published, entitled Nostradamus und das zweite Gesicht, written by Prof. d. Dr. E. Dennert (1861-1942), nature scientist, philosopher and founder and chairman of the Keplerbund. In a time in which according to Dennert the interest in the occult increased and in which in several countries parapsychological research was developed, he asked if one could find out if Nostradamus, who often was ridiculized, yes/no had the gift of clairvoyance. In Nostradamus und das zweite Gesicht, Dennert discussed a number of Century-comments, notably Loog's Die Weissagungen des Nostradamus. For Dennert, this book was interesting, since Loog by means of a cipher key (which Dennert extensively discussed) had arranged the quatrains in order of fulfillment. Regarding Loog's comments in connection with the future, Dennert wrote that the quatrains were that gloomy that they don't give concrete information which leads to certainty. About Loog's comments in connection with events in the past, Dennert wrote that they irrevocably proved that Nostradamus described events in his quatrains which occurred in the years between 1555 and 1920. This brought him to the conclusion that the gift of clairvoyance is a real thing, which shows that man is more than a collection of atoms and that there is a clarity which raises above materialism, which renders the beauty of the material world and the depth of scientific knowledge pale.


Loog's ongoing interest in the Centuries
From a number of books and magazines, it becomes clear that until at least 1940, Loog kept on studying the Centuries and wrote or spoke in public about his findings.

1922 [1921]: rumours about a new Century-comment by Loog
In Mysterien von Sonne und Seele (Berlin, 1922 [1921]), Kritzinger
made some remarks which show that he and Loog heavily exchanged views about Nostradamus and the compilation of the Centuries and that he was willing to publish a new Century-comment, written by Loog. As far as known, this plan has not been realized.[

1922: lecture Die Entschlüsselung der Prophezeiungen des Nostradamus
The pages 169 and 170 of the March-issue of volume 1922 of Psychische Studien contain a review of a lecture which Loog held for the Berliner Psychische-Studien-Gesellschaft on January 23, 1922. This lecture, entitled Die Entschlüsselung der Prophezeiungen des Nostradamus, was given in the Guttmann-room, Bülowstraße 104 in Berlin, the permanent location where the Psychische-Studien-Gesellschaft held her meetings. The audience was given the opportunity to debate. 
After a brief discussion of the contents of Die Weissagungen des Nostradamus, Loog discussed his polemics with Von Klinckowstroem which was published in Psychische Studien
Fascinating political statements of Loog in connection with the actual political situation of those days led, according to the anonymous reporter, to the wish that he would publish more about his efforts. Loog told that more could be expected within a couple of years. Unfortunately, the reporter did not describe the nature of Loog´s political statements. In Die Weissagungen des Nostradamus, Loog wrote about the political circumstances in Germany after World War I a.o. that it was predicted in quatrain 10-46 that on a certain moment, Germany would no longer be a republic, but a monarch would rise and perhaps an emperor. Germany would also break the Versailles Treaty, which Loog considered to be most humiliating for Germany. Writing about the Versailles Treaty, Loog saw a repeat of the circumstances which followed the Westphalia Treaty in 1648. As a result of that Treaty, Germany's prosperity came to an end and it took Germany almost 200 years to recover. Counting from 1919, the year in which the Versailles Treaty took effect, Germany again would need about 200 years to become once again a leading power. England's decline would begin in 1939. The next World War would begin around 2100, with Germany and France fighting each other

1939: a finished manuscript
In World War II, Kritzinger became involved in the compilation of national-socialist propaganda, based upon the Centuries and/or Century-comments. In 1961, he told the British researcher Ellic Howe that Loog gave him a manuscript in December 1939; Loog had made a new translation of the Centuries and had given new comments. Kritzinger said that he did not give this manuscript to the Ministry of Propaganda; he considered it not suited for psychological warfare. It is not clear what he did with it in later years.[

1940: a reply in Der Reichswart: Prophete rechts - Prophete links - war Nostradamus wirklich Scharlatan und Betrüger?
By the end of 1940, the national-socialist weekly Der Reichswart published a letter on Nostradamus and the Centuries, written by Loog. To this letter, the title
Prophete rechts - Prophete links - war Nostradamus wirklich Scharlaten und Betrüger? was given. On this website, it is entitled Nostradamus Scharlatan? In this letter, Loog replied to a sceptical article about Nostradamus and the Centuries, previously published in Der Reichswart. By means of his comments in Die Weissagungen des Nostradamus, about which Loog wrote that it was sold out for years, he wanted to prove that Nostradamus was right by discussing a number of quatrains which, according to him, were fulfilled in previous years until 1940.[4] Loog did not refer to other publications he wrote. This indicates that between 1921 and 1940, no book by Loog about Nostradamus was published and that the manuscript he gave to Kritzinger was not published.


The fortune of Loog's 1921-comment on quatrain 03-57
In the study of the fortune in World War II of the Centuries and Century-comments, Loog's comment on quatrain 03-57 plays an important part. In Die Weissagungen des Nostradamus, Loog linked the beginning of the time span of 290 years of this quatrain to 1649, the year in which the British king Charles I was beheaded. Loog silently had copied this link from Merckwürdige Fata Der Groß-Britanischen Crone Sint der Zeit da die Religion reformiret worden (D.D. = Dietrich von Dobbeler, Hambourg, 1714). For 1939, the year in which the time span of quatrain 03-57 would come to an end, Loog foresaw the last and most severe crisis in England in a series of seven, counting from the beheading of Charles I, and at the same time a crisis in Poland. In Mysterien von Sonne und Seele, Kritzinger quoted this comment. After the German invasion in Poland in September 1939, this comment was taken out of its context and linked to this invasion. For dr. Paul Joseph Goebbels, the German Propaganda minister, this link was reason to lose himself in the Centuries. He decided to use them for psychological warfare, in order to exploit the omnipresent superstition.[5] Nostradamus Scharlatan? shows that Loog had the opinion that the events in Poland in September 1939 matched with what he wrote in Die Weissagungen des Nostradamus about quatrain 03-57 in connection with 1939.


Political ideas
From Die Weissagungen des Nostradamus it becomes clear that Loog's political ideas were nationalistic. He turned himself against the use of the Centuries for political purposes.[6] According to Kritzinger, who in December 1939 asked Loog if he wanted to adapt the Centuries to psychological warfare, Loog definitely did not want to become involved in this.[7]  
As far as I am concerned, Loog's Nostradamus Scharlatan? is not written for propaganda reasons. It is a letter, which is the result of Loog's ongoing research. Nostradamus Scharlatan? shows that in 1940, Loog was convinced that the Centuries would be fulfilled, that he had derived a key which enabled him to comment them and that the major part of his comment in Die Weissagungen des Nostradamus fitted to what happened in the past years. 
Loog was not a member of the NSDAP. His name does not occur in the NSDAP-membership files which are preserved in the Bundesarchiv.

The fortune of Die Weissagungen des Nostradamus
The eighth edition of Die Weissagungen des Nostradamus was the last edition which was published before the outbreak of World War II. In 1940, the fifth and the sixth edition were reprinted, apparently without informing Loog, who by the end of 1940 in Nostradamus Scharlatan wrote that his book was sold out for years.
in 1941, due to the Aktion-Heß, a razzia among astrologers and occultists in Germany, following the flight on May 10, 1941, of Rudolf Heß, Hitler's deputy, to England, the Gestapo confiscated all astrological and occult literature and ordered the publishers of these books to close their office. Thus, Die Weissagungen des Nostradamus was taken out of print and Johannes Baum publishers had to cease their activities. 
After World War II, Johannes Baum publishers resumed her activities, but Die Weissagungen des Nostradamus remained unpublished. 
The German Century-scholar Karl Drude, who as a soldier got wounded in his knee in World War II, kept on studying Loog's hints about the key with which the quatrains might be arranged in the proper order. In 1962, Das magische Quadrat des Nostradamus was published in Munich. In this book, Drude presented a magic square which contained a continuous chain of the Latin lines in the Preface to Cesar and the Epistle to Henry II, which he had arranged in a particular order. In 1963, Nostradamus - ein Leben in der bedeutendsten Zeitwende des Abendlandes und seine Auferstehung was published, also in Munich. In this book, Drude discussed a.o. the life of Nostradamus and the fortune of the Centuries from the beginning of their existence. In 1969, he wrote an extensive introduction to the re-edition of the 1668-J.Ribou-edition of the Centuries.


Hitler and Die Weissagungen des Nostradamus
In spring 1945, according to an article in the edition of February 7, 2004 of the Dutch weekly De Groene Amsterdammer, written by Pieter van Os and Sander Pleij, soldiers of the American 101st Airborne Division found in a salt mine, close to Berchtesgaden, where Hitler had his headquarters, about 3.000 books which had been part of Hitler's library. It is almost impossible to determine with absolute certainty which of these books he actually had read. The books were transported to the American Library of Congress. About 1200 of them contained Hitler's ex-libris. These books were grouped together in one collection, the Third Reich Collection. The other books became part of the general collection of the American Library of Congress ore were sold, in case the library already possessed a copy.
At least two authors report that Die Weissagungen des Nostradamus was one of the books of Hitler's book collection. One of these authors was the German historian Michael Hesemann. In
Hitlers Religion - die fatale Heilslehre des Nationalsozialismus (Munich, 2004), he wrote that Die Weissagungen des Nostradamus contained the prediction of the rise of Hitler, based upon quatrain 03-58. In 2008 in New York, Hitler's private library - the books that shaped his life (New York, 2008) was published, written by the historian Timothy W. Ryback. Ryback had made a list of the more than 16.000 books which Hitler possessed and which were kept in several places. One of these books was Die Weissagungen des Nostradamus. At present, the mentioned copy of this book is part of the collection of Brown University, Providence, Rhode Island. According to Ryback, this book of 120 pages contained the prediction that in 1939, a Second World War would begin. From the fact that the pages which contained this prediction were uncut, Ryback derived that Hitler had not read this prediction.
Hesemann's information about quatrain 03-58 is not reliable. In Die Weissagungen des Nostradamus, Loog did not discuss this quatrain, he even did not quote it, not even partially. The first Century-scholar who linked quatrain 03-58 to the birth and rise of Hitler, was dr. Bruno Winkler in Nostradamus und seine Prophezeiungen für das zwanzigste Jahrhundert (Görlitz, 1939 [1938], p.37-38). Therefore, the question rises from which publication Hesemann copied the link between quatrain 03-58 and the rise of Hitler and attributed it to Loog.
Ryback's information is also not reliable. The Brown University owns a copy of the fourth of the fifth edition of Die Weissagungen des Nostradamus. Both editions count 138 pages instead of 120, as Ryback writes. Further, Loog wrote about 1939 that in that year a crisis of unknown nature, the last one in a series of seven, would occur in England and at the same time a crisis (of unknown nature) would occur in Poland. The next world war, counting from 1914, would occur around 2100 AD. In Die Weissagungen des Nostradamus, Loog wrote nothing about a world war which would begin in 1939. Perhaps Ryback linked the crises which Loog discussed to the German invasion in Poland. In that case, he did not verify enough the context of Loog's comment. Besides, Ryback's information lacks relevancy, it only contributes to the myth that Hitler was fascinated by the occult.
It is not for the first time that rumours about Hitler's interest in the occult circulate, which at first sight seem to be quite plausible, but later, after thorough investigation, are not tenable. In Nostradamus - Der Prophet der Weltgeschichte (Berlin, 1953, p.79-80) the German Century-scholar and former national-socialist propagandist dr. Alexander Max Centgraf wrote, using the author's pseudonym Centurio, that Hitler probably knew quatrain 03-58. When Centgraf in 1939 got a copy of a 1568-P.Rigaud-edition of the Centuries, the librarian who was present at that time, said that this book had just been sent back from the Reichskanzlei, that there was a page marker between the pages 58 and 59 and that quatrain 03-58 was marked. According to Nostradamus - Prophetische Weltgeschichte (Centurio [Centgraf], Bietigheim, 1968, p.197-198), this was a red mark. On page 260 of Nostradamus - Der Prophet der Weltgeschichte and page 262 of Nostradamus - Prophetische Weltgeschichte, Centgraf wrote that the copy of the 1568-P.Rigaud-edition which he saw in the Staatsbibliothek Berlin (catalogue number Na 7590), had disappeared. Centgraf's reports can be refuted. The copy of the 1568-P.Rigaud-edition of the Centuries to which he referred, is kept safe and sound in the Berliner Staatsbibliothek, carrying the catalogue number Na 7590, and quatrain 03-58 is not marked at all.


The author expresses his gratitude to the Deutsche Post AG - Zentrale - Corporate Real Estate (53250 Bonn) for photocopies of relevant pages of the Rangliste der höheren Reichs-Post und Telegraphenbeamten (1916 and 1919), the Verzeichnis der höheren Beamten der Reichs-Post und Telegraphenverwaltung (1922) and the Verzeichnis der höheren Beamten der Deutschen Reichspost (1928, 1938, 1939 and 1942).
