Wilhelm Prinz von Hessen-Philippsthal-Barchfeld Archives

POST 157, POSTSCRIPT: USING AI TO CONFIRM THE MISIDENTIFICATION OF REINHARD HEYDRICH, “THE BUTCHER OF PRAGUE” IN POSTS 133, PARTS I & II

Note: In this postscript to Post 157, I discuss the evidence I uncovered with the help of two informants that Reinhard Heydrich’s look-alike, Wilhelm Prince von Hessen-Philippsthal-Barchfeld, was a member of the Schutzstaffel or SS.

One of my readers questioned whether Wilhelm Prinz von Hessen-Philippsthal-Barchfeld (1905-1942), Reinhard Heydrich’s doppelgänger in the group photo taken at Castle Kamenz in Silesia (today: Kamieniec Ząbkowicki, Poland) in 1936/37, was ever a member of the Schutzstaffel or SS. The implication is that if Wilhelm von Hessen was not a member, he could not have been photographed in an SS uniform at Castle Kamenz, ergo it’s not him. Both the reader who furnished the picture as well as the reader who questioned the identification of Reinhard Heydrich agree that the person is wearing a black SS uniform.

As I very explicitly stated in Post 157, I have no expertise in German military uniforms. Even comparing them to known military outfits of the SS and the Wehrmacht, I’m unable to tell which German military service uniform Wilhelm von Hessen is wearing at the gathering at Castle Kamenz. More on this below.

As to whether Wilhelm von Hessen was a member of the SS, and, if so, when he joined, I turned to two German authorities for help. Let me explain what I’ve learned from them.

At the Berlin State Archives there exists a list of members of the National Socialist German Workers’ Party (German: Nationalsozialistische Deutsche Arbeiterpartei or NSDAP), the Nazi Party, who were members of the royal houses. Wilhelm Prinz von Hessen-Philippsthal-Barchfeld’s name can be found on this roster. (Figure 1)

Figure 1. “Prinz Wilhelm von Hessen’s” name among a list of members of the royal houses who belonged to the Nazi Party showing he joined on the 1st of May 1932 and that his Nazi Party number was “1187621”

The unseen column headings from this list of aristocrats who were members of the Nazi Party and the information specific to Wilhelm von Hessen read as follows:

“Region” (Kurhessen)

“Name” (Prinz Wilhelm von Hessen)

“Date of Birth” (1^st of March 1905)

“Member Number” (of the Nazi Party) (1187621)

“Date of Admission” (to the Nazi Party) (1^st of May 1932)

“Remarks” (in Prinz Wilhelm’s case, it shows that he died on the 1^st of May 1942).

It is known that Wilhelm Prinz von Hessen-Philippsthal-Barchfeld actually died on the 30^th of April 1942 in Gor near Bjeloi in Russia.

Separately, my contacts also found “Prinz von Hessen Wilh.,” as he is referred to, listed in the so-called Dienstalterslisten der SS, the SS seniority list. This is proof that he was indeed a member of the SS.

In the process of determining whether Wilhelm von Hessen belonged to the SS, I learned a trivial but astonishing fact. Of the total 648 high-ranking SS officers (i.e., from Standartenführer (colonel) upwards) in 1938, 58 of them or 8.95% were of aristocratic origin. (A Standartenführer was a Nazi Party paramilitary rank used by the SS and other Nazi paramilitary organizations who commanded a unit equivalent to an army battalion consisting of between 300 and 500 men.) This could explain why several high-ranking Nazis were photographed at Castle Kamenz in 1936/37.

Below, I attach the relevant excerpts from the Dienstalterslisten for the four years, 1934-1937, in which his name appears, and discuss and explain as best I can the information that can be gleaned, including the SS service units he served in.

1934 Dienstaltersliste (Figures 2a-d)

Figure 2a. Cover page of the 1934 “Dienstaltersliste”

Figure 2b. First page of the 1934 “Dienstaltersliste” with the key to abbreviations

Figure 2c. Column headings from the page with “Prinz v. Hessen Wilh.’s” name from the 1934 “Dienstaltersliste”

Figure 2d. Line with “Prinz v. Hessen Wilh.’s” name and information

The column headings are as follows:

“Consecutive number”

“Surname & first name”

“Service”

“Nazi Party Number 1-500,000”

“Nazi Party Number 500,001-1,800,000”

“Nazi Party Number over 1,800,000”

“SS Number”

“Sturmführer” (Date rank obtained)

“Obersturmführer” (Date rank obtained)

Prinz von Hessen Wilhelm’s party number “1 187 621” is again shown on the SS seniority list, but in a separate column his SS member number, “52 711,” is now indicated. Wilhelm von Hessen joined the SS as a SS-Sturmführer on the 20^th of April 1934. Sturmführer was a paramilitary rank of the Nazi Party which began as a title used by the Sturmabteilung (SA) in 1925 and became an actual SA rank in 1928. Translated as “storm leader or assault leader,” the origins of the rank dated to the World War I when the title of Sturmführer came to be used.

In 1934 Prinz von Hessen Wilhelm was a member of the service unit abbreviated as “F. Mo. II/27.” “F.” is short for Führer, while “Mo. Sta.” stands for “Motorstaffel,” or motorized squadron. Thus, it appears that in 1934 he was head of the motor assault team of “II Sturmbann of Standarte 27.” Let me try and explain what this means. Bear in mind I know virtually nothing about the organization of the SS.

The number of soldiers in a motorized squadron is unknown but was possibly only a few men. Standarte was a regimental sized unit of the SS. (more on this below) Sturmbann (Sturmbann – Wikipedia) refers to an “assault unit,” and was a paramilitary unit within the Nazi Party. As previously mentioned, the term originated from German shock troop units used during World War I who were characterized by their aggressive tactics and were often at the forefront of assaults. Putting this together suggests Wilhelm von Hessen was the motorized squadron leader of the second assault unit of Standarte 27.

The 1934 Dienstaltersliste is one source of the information in German Wikipedia on Wilhelm von Hessen’s service unit.

1935 Dienstaltersliste (Figures 3a-d)

Figure 3a. Cover page of the 1935 “Dienstaltersliste”

Figure 3b. First page of the 1935 “Dienstaltersliste” with the key to abbreviations

Figure 3c. Column headings from the page with “Prinz v. Hessen Wilh.’s” name from the 1935 “Dienstaltersliste”

Figure 3d. Line with “Prinz v. Hessen Wilh.’s” name and information

The number of column headings in the 1935 Dienstaltersliste was expanded to two side-by-side pages. The previously referred to rank of Sturmführer was now referred to as an Untersturmführer. A SS-Untersturmführer was the first commissioned SS officer rank, equivalent to a second lieutenant in other military organizations.

Translated, the left-hand page columns included the following information:

“Consecutive number”

“Surname & first name”

“Epee”

“Ring”

“SA sports badge”

“Reich sports badge”

“Service”

“Nazi Party Number 1-1,800,000”

“Nazi Party Number over 1,800,000”

“SS Number”

“Date of birth”

Several of the columns above refer to orders and decorations awarded during World War I by the German Empire, then later by the Nazis.

The right-hand page columns included the expanded list of SS paramilitary ranks, under which the date the soldier attained that rank is shown:

“Untersturmführer”

“Obersturmführer”

“Hauptsturmführer”

“Sturmbannführer”

“Obersturmbannführer”

“Standartenführer”

“Oberführer”

“Brigadeführer”

“Gruppenführer”

“Obergruppenführer”

From the 1935 Dienstaltersliste, we learn that Wilhelm von Hessen was promoted to an SS-Obersturmführer on the 9^th of November 1934. A SS-Obersturmführer was typically a junior company commander in charge of fifty to a hundred men.

Then on the 20^th of April 1935 he was promoted to an SS-Hauptsturmführer. This rank was a mid-level commander who had equal seniority to a captain (Hauptmann) in the German Army and the equivalency of captain in foreign armies. (Figure 4)

Figure 4. Circled the three SS ranks Wilhelm von Hessen attained, “SS-Untersturmführer,” “SS-Obersturmführer,” and “SS Hauptsturmführer”

By 1935 Wilhelm von Hessen was now attached to the “6 Mo. Sta.,” believed to mean that he was then part of the “6 Motor-Standarte.” Again, the number of soldiers in this motorized squadron is unknown. Also unclear is whether the “6 Motor-Standarte” equates to the 6^th SS-Standarte.

Figure 6c. Column headings from the page with “Prinz v. Hessen Wilh.’s” name from the 1937 “Dienstaltersliste”

Figure 6d. Line with “Prinz v. Hessen Wilh.’s” name and information

According to the Dienstalterslisten, Wilhelm von Hessen was assigned to new units in both 1936 and 1937. In 1936, he had a position in the “Stammabt. Bez. 14.” “Stammabt.” stands for “Stammabteilung,” which was a unit of the so-called Allgemeine SS (more on this below) in which men older than 45 years of age or SS members no longer fit for service were grouped together. These “Stammabteilung” were in turn divided into “Bezirke” or districts. Wilhelm von Hessen’s assignment to this organizational unit is puzzling since in 1936 he was only 31 years old and had no known physical disabilities. Perhaps he served in an administrative capacity in this service?

By 1937 Wilhelm von Hessen was no longer with the Stammabt. Bez. 14. but had been reassigned to the SS Abschnitt XXVII. This unit had originally been established in November 1933, but by October 1936 had been reorganized. SS-Abschnitt XXVII was primarily an administrative and organizational unit within the Allgemeine SS. It did not directly engage in major military campaigns or operations, but instead was focused on overseeing SS activities, recruitment, and coordination within its designated area. While the unit was not involved in combat, SS Abschnitt XXVII played an essential role in supporting the Nazi regime and its ideology.

Let me explain two things I mentioned above, namely, the Allgemeine SS and the Standarte.

Both of my informants explained something that has been a source of confusion for me, namely, Wilhelm von Hessen’s membership in the SS while also serving as an officer in the Wehrmacht, the unified armed forces of Nazi Germany from 1935 to 1945. Wilhelm was a member of the so-called “General SS,” or Allgemeine SS which was the administrative and the non-combative part of the SS. This is not to be confused with the Waffen-SS which was the combat branch of the Nazi Party’s paramilitary Schutzstaffel organization.

Additionally, Wilhelm von Hessen apparently joined the Wehrmacht as an officer candidate in 1935 (i.e., “Krad 2” in Eisenach, Germany). Thus, he also embarked on a military career. According to one authority, until the outbreak of war in 1939, it was possible for a German to belong to both the SS and the Wehrmacht.

Supporting this, in Wikipedia, under the discussion about the Allgemeine SS the following sentence is tucked in: “SS members could also hold reserve commissions in the regular military as well as a Nazi Party-political rank.” Thus, as it relates to Wilhelm von Hessen, he could have been a member of the non-combative part of the SS, the Allgemeine SS, and worn an SS uniform, but also had a commission in the Wehrmacht, thus separately worn their outfit. And this seems to be supported by the fact that in the photo of him at Castle Kamenz he is in his black SS uniform but in another photo from the same period he is wearing his Wehrmacht uniform. (Figure 7)

Figure 7. Wilhelm von Hessen in his Wehrmacht uniform from a photo taken on the 30th of November 1936 at the wedding of his sister-in-law, Princess Luise von Preußen (1912-1973)

Relatedly, another reference in German Wikipedia under Allgemeine SS states the following: “In 1939, the Allgemeine SS reached is pre-war peak with more than 260,000 members. During the second World War (1939-1945), around 60 percent of their members (around 160,000) served in the Wehrmacht (Army, Air Force, Navy) and around 36,000 in the ranks of the Waffen-SS.”

Putting this in context is another quote from Wikipedia under the discussion for the 6^th SS-Standarte: “When World War II began in 1939, the Berlin SS regiment slowly began losing its members to regular military service, since mustering Allgemeine-SS personnel were not exempt from conscription.” Quite simply, then, as the war began and as Germany’s fortunes changed, members of the Allgemeine-SS began to be conscripted into the Waffen-SS and the Wehrmacht.

As discussed in Post 157, in the 1936/37 group photo Wilhelm von Hessen is wearing the letter “M” on his collar tab. This is the badge of the Motor-Standarten of the SS. As previously mentioned, according to the Dienstaltersliste der SS for 1935, he was a member of the 6. Motor-Standarte. The SS-Standarte was the primary regimental-sized unit of the Allgemeine-SS. There were 127 SS-Standarten although by 1945 most existed only on paper never reaching their prescribed strength.

The Standarten regiments each had their own number, but were also referred to by other names, such as location, a popular name, or an honorary title. After Hitler became Chancellor of Germany in 1933, the 6^th SS-Standarte, for example, adopted the honor title of “Charlottenburg” and often participated in several major Nazi Party rallies held in the German capitol.

From German Wikipedia, I know that Wilhelm fought in WWII as a tank officer (i.e., Captain of the Reserve) and deployed with the 2^nd SS Panzer Division in Poland and France, including at Dunkirk; he then fought in Greece and Romania before being killed in the spring of 1942 in Russia. Since the 2^nd SS Panzer Division was an armored division of the Waffen-SS, this suggests Wilhelm transitioned to the combat branch of the SS at some point and presumably was a member of the Waffen-SS when he was killed.

In closing, I was able to determine through primary source documents that Wilhelm von Hessen joined the Nazi Party in 1932, the SS in 1934, and was part of the non-combative arm of the SS, the Allgemeine SS, for some period. Simultaneously in 1935, Wilhelm apparently joined the Wehrmacht. However, by the time WWII started in 1939, he was a member of the 2^nd SS Panzer Division, one of the armored divisions of the Waffen-SS, suggesting he died fighting for the SS.

None of the new information I obtained and discussed changes my assessment that Wilhelm Prinz von Hessen-Philippsthal-Barchfeld (1905-1942) is the individual pictured in the group photo taken at Castle Kamenz in 1936/37.

POST 157: USING AI TO CONFIRM THE MISIDENTIFICATION OF REINHARD HEYDRICH, “THE BUTCHER OF PRAGUE” IN POSTS 133, PARTS I & II

Note: In this post, I discuss the process I went through to confirm that I’d incorrectly identified the sinister Nazi Reinhard Heydrich in a group photo taken in 1936/1937 at Castle Kamenz (Kamieniec Ząbkowicki, Poland). To prove this to my satisfaction, I made use of an AI-powered tool.

POST 133: “THE BUTCHER OF PRAGUE,” THE STORY BEHIND A UNIQUE PHOTO OF REINHARD HEYDRICH (PART II)

An astute reader recently informed me the person I had identified in Posts 133, Parts I & II, as Reinhard Heydrich (Figure 1), the Nazi’s notorious “Butcher of Prague,” in a group photo taken at Castle Kamenz in Silesia (today: Kamieniec Ząbkowicki, Poland) in 1936/37 (Figure 2) is not him. The picture in question was originally sent to me by a very reliable informant claiming a noted scholar had recognized Reinhard.

Figure 1. The individual in the group photo taken at Castle Kamenz (today: Kamieniec Ząbkowicki, Poland) in 1936/37 who I mistakenly identified as the notorious Nazi henchman Reinhard Heydrich

Figure 2. The group photo taken at Castle Kamenz (today: Kamieniec Ząbkowicki, Poland) in 1936/37

The German gentleman who questioned the identification is a physics teacher in Dresden with an avid interest in history, particularly German military history up to 1918. The man grew up in Gotha in the former German Democratic Republic or East Germany. According to the reader, Reinhard Heydrich’s doppelgänger is Wilhelm Prinz von Hessen-Philippsthal-Barchfeld (1905-1942), and he sent me a link to a photo of him in his military ensemble as well as his bio. (Figure 3) He claims that in the group picture Wilhelm von Hessen, who was head of a “Motor-Sturmbann” of the SS-Standarte 27, is seen wearing his military uniform with the collar tabs “M” for Motor-Sturmbann; even on the highest resolution picture of this gathering, I have difficulty distinguishing the collar tabs.

Since this is my blog the responsibility for fact checking the accuracy of the information I publish in my posts ultimately rests on my shoulders. Given the lengths I’ve gone to caution readers about cloning vital data from other people’s ancestral trees without sourcing the primary documents and verifying their accuracy, I decided I needed to take a similarly rigorous approach in determining whether the amateur historian is accurate.

Let me explain to readers who Wilhelm von Hessen was and whether it is even conceivable he could have been photographed at Castle Kamenz at the time the picture was taken. In 1936/37 Castle Kamenz was owned by Friedrich Heinrich von Preußen (1874-1940) (Figure 4) shown elegantly attired and seated in the front row of the group picture, second from the left. His younger brother was Friedrich Wilhelm von Preussen (1880-1925) (Figure 5) who obviously was not in attendance since he had died prematurely about a dozen years earlier.

Figure 4. Friedrich Heinrich von Preußen (1874-1940), owner of Castle Kamenz at the time the 1936/37 photo was taken

Figure 5. Friedrich Wilhelm von Preußen (1880-1925), Friedrich Heinrich’s older brother who predeceased him

Friedrich Wilhelm was a member of the House of Hohenzollern and a great-grandson of King Frederick William III of Prussia. He was married to Princess Agatha of Hohenlohe-Schillingsfürst from Ratibor & Corvey (1888-1960) (Figure 6), seated as a widow in the center of the front row (Figure 7); together they had four daughters. (Figure 8) The third daughter, Princess Marianne von Preußen (1913-1983) was married to Wilhelm von Hessen. Thus, based on family connections, it is entirely plausible that he attended the family gathering at Castle Kamenz in 1936/37.

Figure 7. The widow Agatha of Hohenlohe-Schillingsfürst at the time the 1936/37 photo was taken

Figure 8. Friedrich Heinrich von Preußen, Princess Agatha of Hohenlohe-Schillingsfürst, and their four daughters as children

Obviously, the individuals in attendance at the gathering at Castle Kamenz are unidentified though some are familiar to the reader who furnished the group picture. I’m not entirely positive but think Princess Marianne von Preußen is standing in the second row, the third person from the left dressed in white. Though Friedrich Wilhelm and Princess Agatha’s four daughters were born between 1911 and 1919, as young women they are often difficult to tell apart.

The reader who shared the original photo included side-by-side photos of Reinhard Heydrich and the man purported to be him in the group picture. (Figure 9) Given that Heydrich’s identity had putatively been confirmed, I did not compare the images as carefully as I should have when writing Posts 133, Parts I & II. Had I done so initially, I might have observed a few things that later triggered some doubts. First, I noticed in the picture that is assuredly of Heydrich that he had a narrower face, longer nose, and bigger ears than the individual on the right. Second, and this is much more impressionistic, the person in the group picture is broadly smiling, an attribute I would hardly associate with as sadistic an individual as Heydrich.

Figure 9. Reinhard Heydrich (left) and his doppelgänger

Trained as an archaeologist steeped in the scientific method, I was still not convinced the person in the group picture was Wilhelm von Hessen. Because the link sent to me by the amateur historian depicting Wilhelm in his military uniform was not conclusive (see Figure 3), I went in search of other pictures of him. Because Wilhelm came from a royal family and married into another royal family, I had the good fortune to find several of them on the Internet and in my own collection of photos.

The first high quality picture I found of Wilhelm von Hessen was taken at the marriage of one of his wife’s sisters, Princess Luise von Preußen (1912-1973) to Moritz Richard Bruno Wilhelm Schmaltz (1901-1983) on the 30^th of November 1936, possibly at Castle Kamenz. (Figure 10) It shows Princess Agatha, her four daughters, three sons-in-law, and one grandson. On the very far right in this picture can be seen Princess Marianne von Preußen (1913-1983) and her husband Wilhelm von Hessen. Regrettably, comparing this image of Wilhelm von Hessen to the group photo again yields no definitive answer to the naked eye as to whether it was Wilhelm.

Figure 10. From left to right: unidentified person (possibly Princess Marie’s husband, Aloys Rudolf Hug (1885-1972)), Princess Elisabeth von Preußen (1919-1961), Princess Agathe, unidentified grandson, Princess Luise von Preußen (1912-1973), her husband Wilhelm Schmaltz (1901-1983), Princess Marie von Preußen (1911-2005), Princess Marianne von Preußen (1913-1983), and her husband Prince Wilhelm von Hessen (1905-1942) on the 30th of November 1936

My Internet search continued. I found an undated group photo of Wilhelm von Hessen including him and his four siblings. (Figure 11) He is pictured fourth from the left but once more the evidence is not clear cut that he is the person in the group picture.

Figure 11. An undated picture of Wilhelm von Hessen with his four siblings in civilian clothes

Another headshot of Wilhelm von Hessen in his military uniform, also undated, was not conclusive. (Figure 12)

Figure 12. An undated photo of Wilhelm von Hessen in his military uniform

Finally, I had the good fortune to find in Geni a high-quality picture of Marianne von Preußen and Wilhelm von Hessen, possibly from around the time they were married on the 30^th of January 1933 (Figure 13); at the time, Marianne would have been 20 years old and Wilhelm 28 years, the approximate ages they appear to be in the picture. A simple visual comparison of this image of Wilhelm to the person in the group photo left me fairly convinced they were the same person. I asked several friends who I know from previous experience are adept with visual comparisons, and they agree. Unfortunately, the reader who originally sent me the group photo disagrees.

Figure 13. Wilhelm von Hessen and his wife Princess Marianne von Preußen possibly around the time they were married on the 30th of January 1933

While I have no expertise in this area, both readers agree the man in the 1936/37 group picture is wearing a Schutzstaffel or SS uniform. However, the informant who sent the group photo claims that Wilhelm von Hessen did not switch from the Wehrmacht to the SS (i.e., German soldiers could not be members of both units simultaneously) until right before the Nazi invasion of France on the 10^th of May 1940. Unfortunately, I can’t independently verify when von Hessen joined the SS. On his 30^th of November 1936 photo, Wilhelm von Hessen is supposedly wearing a Wehrmacht uniform. (Figure 14) Based on this apparent discrepancy, I theorize the group photo was taken in late 1936 or in 1937 after the November 1936 marriage, by which time Wilhelm von Hessen was then a member of the SS.

Figure 14. November 1936 photo of Wilhelm von Hessen and Princess Marianne von Preußen at Princess Luise’s marriage in his Wehrmacht military uniform

Having convinced myself that the amateur historian is correct that the person in the 1936/37 group picture is not Reinhard Heydrich but Wilhelm von Hessen, as a lark I decided to see whether I could find an artificial intelligence (AI) application which could strengthen my case. I found an AI-powered tool which allows me to do precisely what I was looking to do, namely, compare two faces to measure similarity. It is called “FaceShape” and below is the link to this tool:

https://www.faceshape.com/face-compare

I’m admittedly not adept at using new technology, so the attraction of FaceShape is that it’s supremely easy to use.

Juxtaposing the images of Reinhard Heydrich and that of the person in the group photo originally sent by the first reader yields a low probability of only 27.04% that they are the same individual. (Figure 15) By comparison when I compare the known image of Wilhelm von Hessen from his sister-in-law Princess Luise’s 1936 marriage to the person in the group photo, FaceShape claims a 100% probability they are the same person. (Figure 16) Another comparison that yielded a 100% match was Wilhelm von Hessen’s photo from his sister-in-law’s marriage to one of him in his military uniform. (Figure 17) Readers can see the results of the various other images I contrasted. (Figures 18-20)

Figure 15. FaceShape comparison of Reinhard Heydrich and his doppelgänger showing only a 27.04% likelihood they are the same person

Figure 20. FaceShape contrast of two known images of Wilhelm von Hessen indicating a 63.71% probability they are the same person

Comparing the photos I found of Wilhelm von Hessen to one another, then to the person in the group picture from 1936/37, sets my mind at ease that it is indeed Wilhelm von Hessen. However, I want to be very clear with readers that FaceShape is not perfect. Based on some of the images I juxtaposed, the application obviously does not work well with poor resolution images; where the person in question is partially blocked by another individual; where siblings are involved that resemble one another or are of similar age; when known pictures of the same person are from earlier in life vs. later in life; or in distinguishing gender.

In closing, I would merely say that I consider FaceShape or similar AI-powered applications to be one tool in an arsenal that genealogists can use to further one’s research and possibly resolve thorny identification questions. It clearly requires human interpretation after the tool is applied to consider the question of whether the results are logical and make sense. While I may not have convinced the original reader that Reinhard Heydrich is not in the group photo taken at Castle Kamenz, I have proven to my satisfaction the person in question is Wilhelm von Hessen, not Heydrich.
