POST 68: DR. JULIUS BRUCK AND HIS INFLUENCE ON MODERN ENDOSCOPY

UPDATED ON MAY 18, 2021

(UPDATES SHOWN IN RED)

 

Note: In this post, I talk about Dr. Julius Bruck, my first cousin three times removed, who laid the technical foundations for the development of modern endoscopy through his inventions of the stomatoscope and urethroscope.

I first heard about my distant and renowned ancestor, the dentist Dr. Julius Bruck (1840-1902) (Figure 1), from one of my German first cousins, probably in the 1990’s, when we initially met. I also learned he was buried in the Old Jewish Cemetery in Breslau [today: Wrocław, Poland] (Figure 2), and that his grave still exists. At the time, I was unaware of any surviving tombs of Bruck ancestors, although in the years since I’ve discovered others. For reference, two quick points. First, Dr. Julius Bruck’s father was Dr. Jonas Bruck (Figure 3), himself a dentist, whom I introduced to readers in Post 60 as the precocious lad who attended Ratibor’s Gymnasium, high school, in 1819 in its inaugural year. Second, Dr. Julius Bruck was my first cousin thrice removed.

My wife Ann Finan can attest to the numerous cemeteries we’ve visited across Europe seeking discernible proof of my ancestors’ connections to different places. In 2014, during a lengthy 13-week trip exploring cities and towns between Poland and Spain associated with my family, we stopped in Wrocław, Poland and visited Dr. Julius Bruck’s tomb. A photo of the very distinguished dentist is featured on a panel at the entrance to the Old Jewish Cemetery, pinpointing his tomb, alongside other prominent Jews interred there. (Figures 4a-b) Upon touring Julius’ grave, my wife and I discovered he is interred alongside his father Dr. Jonas Bruck (1813-1883), and their respective wives, Rosalie Bruck née Marle (1817-1890) and Bertha Bruck née Vogelsdorff (1843-1917). (Figures 5a-b) At the time, the headstones had fallen into disrepair, although have subsequently been beautifully restored. As an aside, on ancestry.com, I even found Bertha Bruck’s death announcement. (Figure 6)

Seeking to learn more about Dr. Julius Bruck, beyond what is easily retrievable from a web search, I inquired with cemetery personnel and was introduced to the on-site Branch Manager, Museum of Cemetery Art (Old Jewish Museum), Ms. Renata Wilkoszewska-Krakowska. (Figure 7) I learned the Old Jewish Cemetery is a branch of the City Museum of Wrocław, and that Jews, obviously, are no longer interred there. Archivists and museum personnel are naturally curious and intrigued when some foreigner shows up asserting an ancestral connection to someone from their area, particularly when that individual was Jewish. Such was the case in this instance. While obtaining little new information about Dr. Julius Bruck, I’ve learned and explained to readers the value of developing local contacts, so I resolved to stay in touch with Renata. Before parting ways, Renata asked me whether I knew or was related to a Dr. Erich Bruck (Figure 8), also buried in the Old Jewish Cemetery, whose very distinctive picture she gave me a copy of. Beyond having a common surname, I conceded I had no knowledge of this individual. That was five years ago, but in the subsequent post, I will tell readers how I recently stumbled across information about this previously unknown Bruck.

Dr. Julius Bruck was born in Breslau on October 6, 1840 and died there on April 20, 1902. He studied dentistry and medicine at the universities of Breslau, Berlin, Bonn and Paris, and received his diploma as dentist from Berlin in 1858 and as Doctor of Medicine from Breslau University in 1866. In 1859, he became assistant to his father Dr. Jonas Bruck, and eventually succeeded him in his practice. In 1871 he was admitted to the faculty of Breslau University as privatdozent, university lecturer, receiving the honorary title of professor in 1891.

Not only was Dr. Julius Bruck one of the most famous dentists of his time, but he was also a fighter for dentists’ education and a very successful inventor. He gained prominence in the mid-1860’s for his inventions of the stomatoscope (i.e., an apparatus for illuminating the interior of the mouth to facilitate examination) (Figure 9) and the urethroscope (i.e., an instrument for viewing the interior of the urethra), both of which laid the technical foundations for the development of modern endoscopy. Through development of the stomatoscope, Julius applied the same successes that had been achieved for treatments of eye, ear, and larynx diseases to oral and dental diseases using better illumination. (Lutze 2017)

Julius Bruck produced light by using an exposed electrically heated platinum loop, which at the time was the most powerful light source known. He imagined the possibility of placing the source of light in the distal end of an instrument and invented a double glass tube with a water-cooling compartment. This water-cooled apparatus, or diaphanoscope (i.e., an instrument for illuminating the interior of a cavity to determine the translucency of its walls), could transilluminate the bladder by being inserted into the rectum or vagina. (Zajaczkowski & Zamann 2004)

Julius focused on the research of his father in the area of Galvanokaustik, electroplating. In layman’s terms, suffice it to say that, in medicine, electroplating is an operating method that uses galvanic current-generated annealing heat for surgical purposes which is particularly suited for operations in the mouth and rectum. For the first time, Julius used the platinum glow wire, 0.3 to 1 mm in thickness. Julius himself described this method as resulting in the teeth being full illuminated so they were almost translucent; this meant that dental decay and diseases of the mouth could be detected that were invisible to the naked eye. The urethroscope essentially allowed a similar method to be used to illuminate and detect diseases of the bladder.

As previously mentioned, following my and my wife’s visit to Wrocław in 2014, I stayed in periodic contact with Ms. Wilkoszewska-Krakowska. Then, in 2016, Renata sent several photos of the meticulous restoration the City Museum of Wrocław had recently completed of Dr. Julius Bruck and family’s headstones. (Figures 10a-b)

Renata and I have recently re-established contact following a lengthy hiatus. While the subject of our more recent communications has been mostly about Dr. Erich Bruck, who as mentioned will be the focus of the ensuing Blog post, we’ve also discussed the fate of Dr. Julius Bruck’s two granddaughters and daughter-in-law. Since Breslau’s Old Jewish Cemetery is a branch of Wrocław’s City Museum, Renata Wilkoszewska-Krakowska regularly conducts walking tours telling visitors what she’s learned about the Jews interred there and contacts she’s in some cases made with their descendants. (Figure 11)

Julius’s two granddaughters were named Hermine Bruck (1924-1924), who died in infancy, and Renate Bruck, born on the 16th of June 1926. A clue provided by one of my fourth cousins, more closely related to Julius and his son, Dr. Walter Wolfgang Bruck (1872-1937) (Figure 12), suggests Renate may have emigrated to England during or after WWII; I discovered a Renate Bruck listed in a Willesden, Middlesex, England marriage register, showing she had gotten married there to a man named Harry E. Graham in October, 1948. Uncertain whether this was Dr. Julius Bruck’s granddaughter, I ordered a copy of the marriage certificate from England’s General Register Office. It arrived only days ago, and the certificate confirms this is indeed the granddaughter of Dr. Julius Bruck and the surviving daughter of Dr. Walter Wolfgang Bruck. (Figure 13)

The marriage certificate provides additional names that has enabled me to partially work out vital events in Renate’s life. Renate’s full name was “Renate Stephanie Gertrude Bruck.” Not only is Renate’s husband’s full name shown, Henry Ernst Graham, but her future father-in-law’s name is also provided, Hermann Gradenwitz (1876-1940) (Figure 14); this confirms that Renate’s husband anglicized his name upon his arrival in England to “Graham.” Both Renate and her husband had previously been married, Renate to a man named Eugen Walter Mehne, and Harry to a woman named Ruth Philipsborn (1914-2003); Henry and his first wife Ruth, I later discovered, married in 1935 in London indicating Henry had already emigrated from Germany by this time. Renate and Henry were married in the presence of a Marie Luise Gradenwitz (1881-1955), whom I later confirmed was Henry’s mother, née Mugdan. Curiously, Hermann Gradenwitz is buried with a Leo Mugdan, possibly his brother-in-law, as readers may be able to detect from their headstone.

With new names in hand, I turned to ancestry.com and MyHeritage hoping to learn more about Renate and her family. Renate’s first husband, Eugen Walter Mehne, is initially listed in a 1908 Breslau Address Book showing he was an instrumentenmacher, an instrument maker (Figure 15); he is listed in a Breslau Address Book as late as 1939, and by then is a geigenbauer, violin maker. While I was unable to learn when or where Eugen was born or died, the fact that he was already in business in 1908, 18 years before Renate was even born, proves she married an older man. Similarly, her second husband, Harry Graham (aka Heinrich Gradenwitz), was significantly older when they married in 1948, he was 43 and she only 22. Harry, I discovered, was born on the 8th of November 1904 in Berlin, and died on the 7th of March 1959 in London.

I refer readers to Blog Post 101 in which I discuss in much more detail the Mehnes listed in the Breslau address books between 1908 and 1939. Suffice it to say, the Eugen Mehne listed as either an instrumentenmacher, an instrument maker, or geigenbauer, violin maker, between 1908 and 1934 is Albert Eugen Mehne, the father of Eugen Walter Mehne listed in 1935, 1936, and 1939 address books, identified as a geigenbauer or geigenbaumeister, master violin maker.

I found evidence of Renate’s third marriage in 1956 to a man named Gary Newman, thus before her second husband passed away in 1959. (Figure 16) A single reference indicates Renate died as Renate Newman on the 3rd of March 2013 in the United Kingdom.

To date, I’ve found no evidence that Renate ever had any children to continue Dr. Julius Bruck’s lineage. However, in the course of writing this Blog post, on MyHeritage, I just discovered that Renate’s mother, Johanna M. E. Bruck née Graebsch, whose fate was previously unknown to me, may also have emigrated to England. I last found evidence of her existence in a “1939 German Minority Census,” showing that she and Renate were registered as living in Breslau in May 1939 (Figure 17), a most dangerous time. I can find no indication she was murdered in the Holocaust, but the fleeting reference I just stumbled upon suggests she too emigrated to England and died there. As we speak, I’ve ordered the death certificate from the General Register Office for this Johanna Bruck to confirm my suspicion. Watch this space for an update.
