What Became of Tychsen?: The Non-Jewish ‘Rabbi’ and his “Congregation” of Jewish Medical Students

By Dr. Edward Reichman, MD

This essay was inspired by two recent Seforim blog posts, one on Professor Shnayer Leiman’s contributions,[1] and the other on a topic related to R’ Yonasan Eybeshutz.[2]

                                           

In November 16, 2006 an article by Dr. Shnayer Leiman appeared in the newly formed Seforim Blog entitled, “Two Cases of Non-Jews with Rabbinic Ordination: One Real and One Imaginary.” The “real” ordination was bestowed upon Olaf Gerhard Tychsen (1734-1815). In 1759, Tychsen received the title of Haver, a lower form of rabbinic ordination, by Moses the son of Rabbi Zvi Hirsch Lifshuetz. Tychsen is perhaps the only known case in Jewish history of a non-Jew receiving such an honor or degree.[3]

Leiman provides a biography of Tychsen. He pursued studies in Hindustani, Ethiopic and Arabic, as well as Hebrew and Yiddish and became an Orientalist of international renown making significant contributions to cuneiform studies and numismatics as well.[4] During his early years he also pursued various missionary activities in the Jewish community, largely unsuccessful by his own account. 

As Leiman notes, in 1752, while a student at the Christian Academy in Altona, Tychsen attended the lectures of R. Yonasan Eybeschutz. Leiman essentially leaves us at the point of Tychsen’s ordination, with brief mention of his subsequent academic career. What became of Tychsen’s “rabbinic” career after he received this singular distinction? Did he apply for a rabbinic position? Did he maintain any connection with the Jewish community? 

In fact, Tychsen did continue to maintain a strong connection to both rabbinic literature and the Jewish community in varying degrees throughout his life. He is perhaps best known for his involvement in the premature burial controversy, which would earn him a place of infamy in Jewish history. Tychsen taught at the university in Butzow, the residence of the Duke of Mecklenberg. During this period there was concern that physicians were misdiagnosing death, and as a result, people were being buried prematurely.[5] On February 19, 1772 Tychsen sent a letter to the Duke of Mecklenberg regarding the Jews’ burial practice, interring after waiting only three hours, where it is known that there can sometimes be misdiagnosis of death. Tychsen detailed the Jewish origins of hastening burial in general, reflecting familiarity with rabbinic literature. He claimed that the need to bury quickly was established in countries with hot climates, where the body would decompose quickly, not applicable to a country like Germany. He also reported cases of people who were supposedly buried alive.[6] On April 30, 1772, Duke Friedrich of Mecklenburg-Schwerin, in response to Tychsen’s letter, issued an order prohibiting the Jews in his realm from immediately burying their dead and requiring that they rather wait for three days after death before interment. This began what would become a worldwide halakhic debate about the halakhic definition of death and the time of burial.[7]

Tychsen was also peripherally involved with one of Jewish history’s greatest seforim collections. Rabbi David Oppenheim amassed an extraordinary collection of books and manuscripts which languished in storage for years after his death.[8] Tychsen visited the collection for three weeks, reporting on its manuscripts to the Italian Christian Hebraist Giovanni Bernardo De Rossi. He attempted to arouse the interest of potential buyers, including Catherine the Great, Empress of Russia, Duke Karl Eugen of Wurtemberg, and Archduke Frederick Francis I of Mecklenberg. His efforts were to no avail and the collection ultimately found its home in Oxford, where it remains to this day.[9]

Here we highlight a little-known, though more substantive, connection of Tychsen with the Jewish community. One year after his ordination, toward the end of 1760, Tychsen was appointed Professor of Oriental Languages at the newly established University of Bützow in Mecklenburg. It is in this capacity that Tychsen exercised a rabbinic role, becoming a university campus rabbi of sorts for a select group of Jews at the university. Though he may not actually have had a “minyan” of students, nonetheless, his impact on this select group was profound and long lasting, akin to that of a rebbe.[10]

The interactions of Tychsen with the Jewish community must be viewed through a particular lens. Tychsen was a devout Lutheran Protestant and trained and engaged in proselytizing activities in his early life. This fact remains at least in the background of all his interactions with the Jewish students at Butzow and has been evaluated elsewhere. Whether his relationships with the Jewish medical students were primarily or partially motivated by his proselytizing tendencies, or whether his proselytizing endeavors had ceased by then, is a matter of historical speculation.[11] This is not the focus of the present essay.[12]

In his capacity as a faculty member of the University of Butzow Tychsen encountered a number of Jewish students attending the university’s medical school. Though an Orientalist and not a physician or scientist, he nonetheless served as a mentor for these students to whom he was drawn by shared interests and possibly proselytizing intentions. Tychen served this role for all the Jewish medical students who attended the University of Butzow during its twenty-nine years of existence. 

The first Jewish student of the Butzow Medical School, and the first with whom Tychsen developed a relationship was Markus Moses. This relationship has been the subject of a number of dedicated essays.[13] Markus Moses was the son of Moshe ben Meir Harif Lemberger (Lvov), Chief Rabbi of Pressburg and head of its yeshiva. Lemberger, as well as his son Markus, were apparently involved in the Emden- Eybeshutz controversy.[14] Markus (Mordechai) was born in Pressburg in 1729, received a traditional Jewish education, and married. Shortly thereafter, his wife and two young children died. In 1758, after the death of his father, Markus began the study of secular subjects. Over the next few years he traveled to Germany and continued study in various cities, including the field of medicine, ultimately ending up in Butzow in 1763. Aron Isak, the leader of the Jewish community, took him under his wing and orchestrated his admission to the recently founded Butzow Medical School,[15] thus waiving the high taxes imposed upon the Jewish community for new town visitors. The faculty were impressed with Moses’ great intelligence and facility with multiple languages and accepted him, with the approval of the Duke and Professor George Detharding, the head of the faculty, with free tuition. Below is a letter in Hebrew from Paul Theodore Carpov, an Orientalist and Christian Hebraist at Butzow, supporting Moses’ acceptance to the medical school at Butzow and advocating for his financial support as well.[16]

As per the letter, Moses brought with him impressive letters of recommendation not only from the great scholars of “his nation,” but also from those of “our nation.” Carpov also notes the Duke’s approval, as well as the financial issues relating to his application. Carpov was clearly taken by the young Jewish student. 

Below is the record of matriculation of Markus Moses in 1764.

Moses clearly had a predisposition for the field of medicine and was soon relied upon by Detharding to see the latter’s private patients.[17]

Tychsen had a working academic relationship with Moses as evidenced by the multiple research papers Moses wrote under his mentorship. It is remarkable that all of the papers were on Jewish topics. I have found a number of cases, though relatively few in number, of Jewish medical students throughout the centuries who wrote their medical school dissertations on a Jewish related topic,[18] but I have never encountered any student who authored so many Jewish related papers as part of their medical training. The topics included the Samaritan Bible, a discussion of the kosher and non-kosher animals based on the work of Rambam, and an essay on the diseases of the old as reflected in Kohelet (chapter 12).[19] Moses’ graduation dissertation, discussed below, was also on a Jewish topic and was supervised by Tychsen.

Disputatio de Pentateucho Ebraeo-Samaritano, 1765[20]

Essay on kosher and non-kosher animals based on Rambam.[21]

The nature of the relationship Tychsen had with Moses, as well as with other Jewish medical students in Butzow, went far beyond the usual Professor-student model. There wrote each other dozens of letters and continued correspondence for years after graduation.[22] In one letter dated March 16, 1765[23] Moses apologizes for not responding promptly to Tychsen’s previous letter. Moses continues that soon he will either write again, or will see Tychsen in person. Moses signs the letter, hamitavek biafar raglekha.

גבר(א) דכולי() בי החכ(ם) הכולל המפורס(ם) שמו נודע בכל השערי(ם) הפרעפעסאר טיקסן

מרוב טרדות היום אין אוכל לתואר בתואר כראוי לגבר(א) כמותו ובאתי בלישנא קלילא אל תשים עלי חטאת שעדיין לא השיבני על כתב ידו הטהור מה שקבלתי ע”י ערל הבוח(ן) לבות יודע שהזמן גרמ(ה) לי רק זאת יהי(ה) לבו בטוח שהשבוע הבע” (?הא עלינו לטובה) או אכתוב לו או בנשיקת פא”פ (פה אל פה) אדבר בו[24] גם יקבל במתנה צורה של ר’ יהונת(ן) זצ”ל יותר אין לחדש כה המתאבק בעפר רגליו מרדכי מפב (?מפרשברג)ג

 

In the last line, Moses writes that Tychsen will also receive from him a gift of a portrait of Rav Yehonatan zt”l. Moses was obviously aware of the connection between Tychsen and Eybeshutz and believed this would be a meaningful gift. Eybeshutz died in 1764,[25] and his portrait was disseminated shortly thereafter. This is likely the portrait Moses purchased for Tychsen.[26]

As part of the requirements for the completion of a doctorate in medicine at most German universities, the student was required to engage in a public disputation on the topic of their dissertation. [27] The topic of Markus’ disputation was the analysis of a verse in Yehezkel which, according to Moses, reflects an ancient Jewish practice of placing salt of the skin of an infant as a prophylactic against disease. 

Moses engages in an expansive philological and grammatical analysis of the verse then posits that the Jews practiced this procedure and that it protected them from diseases like smallpox. The reason smallpox was prevalent during his time, Moses argues, is because people no longer routinely applied salt to the skin of infants. Moses is the only one of the Jewish medical students at Butzow who wrote his dissertation on a Jewish topic. 

Moses’ disputation was held on January 22, 1766 (11 Shevat, 5526). The event was held in a church, though Tychsen apparently noted that it was primarily a venue for non-ecclesiastic events. This may have been in deference to the halakhic concern about entering a church.[28] A number of Jewish families attended the event. Copies of the dissertation were sent to those invited to the public discourse, and additional copies were provided for the audience on the day of the event. The ceremony began with a Latin oration by the presiding professor, in Moses’ case, Professor Detharding, and was followed by the student’s reading of his dissertation. Upon completion of the reading, designated opponents presented their arguments and criticisms against the substance of the dissertation, with audience members occasionally allowed to participate. This was then followed by the candidate’s rebuttal. Tychsen served as one of the designated opponents for Moses’ disputation. 

On oath was also part of the graduation ceremony, and it typically involved avowing one’s belief in Christianity. Tychsen intervened with the Duke of Mecklenberg on Moses’ behalf to allow him to take his graduation oath invoking the name of the God of Israel as opposed to the Christian deity. He even publicly conversed with Moses in Yiddish at the graduation.[29] 

Below is the approbation of Tychsen appended to the published dissertation of Moses.

Tychsen’s freely inserts throughout allusions to rabbinic literature. He also uses a chronogram for the Hebrew year, typically done in Hebrew publications, and something Tychsen used frequently, as seen in his letters below. 

At the end of the approbation, Tychsen mentions the upcoming (second) wedding of Moses. Below is the handwritten wedding invitation of Moses to Tychsen.[30]

Both the title and signature of the invitation reflect the type of relationship they had. Moses also adds the clever pun of “hazmanah lav milsa,” assuming that Tychsen will appreciate it. 

The other letters appended to Moses’ published dissertation are also of great interest. In addition to Tychsen, another opponent at the disputation contributed a letter. Karl Leopold Carpov,[31] son of the Orientalist and professor at Butzow, Paul Theodore Carpov, who had written Moses’ letter of recommendation for admission (above). The older Carpov had died the previous year. The younger Carpov describes how beloved Markus was to his father, who considered him as another son, and, impressed by his brilliance, spent days and nights studying with him. Karl himself calls Markus his brother. While many focus on Markus’s close relationship with Tychsen, no mention has been made of his relationship with the other Orientalist, Carpov. 

The remaining letters were written by Judah Levi Strelitz,[32] the brother in law of Moses, and Meier (no other name is written), a fellow medical student. 

Moses was not the only Jewish student Tychsen took under his wings. Over the span of decades, throughout the short existence of the Butzow medical school, he endeared himself to a number of Jewish medical students.[33] He taught them, mentored them, and even financially supported them. They in turn sought his personal advice and recommendations, aided him in his intellectual quests, and invited him to their weddings.

Two Jewish medical students who matriculated in 1783 were also close with Tychsen, Isaac Salomonsen and Wulf Levinson. 

Matriculation record from University of Butzow November 24, 1783
Wulf Levinson and Isaacus Salomonsen[34]

Below is Tychsen’s letter to Levinsohn upon his graduation.[35]

Tychsen includes that the Butzow anatomist August Schaarschmidt and Professor Detharding, who had accepted Markus Moses some twenty years earlier, attest to the student’s qualifications.[36]

Below is the letter of Isaac Salomonsen presenting his dissertation to Tychsen.[37]

Below is Tychsen’s letter of approbation for Salomonsen’s dissertation in 1784. He mentions Isaac’s work in botany, which is in some form a continuation of the work of another Butzow medical student Tzadik de Meza, who died at the age of twenty-three.[38]

In another letter,[39] Salomonsen complained bitterly to Tychsen about his classmate Levinson, who had apparently been slandering him. He adds that the great personalities in the history of medicine, Aesculapius, Hygea and Hippocrates would be mourning and turning over in their graves if they knew how Levinson was misrepresenting and dishonoring them and the University of Butzow.

In the letter below dated 1784 from Salomonsen to Tychsen[40] we find a number of the elements common in Tychsen’s relationship with all the Jewish medical students. 

Salomonsen mentions the money he owes Tychsen and explains and apologizes for the delay in repayment. Tychsen routinely loaned money to the Jewish students. Salomonsen then reports that he was unable to obtain the sefer (shu”t Rabbi Moshe Alshikh) and Arabic coins Tychsen had requested. Tychsen was an avid bibliophile and his magnificent and important library was ultimately bequeathed to the University of Rostock, which absorbed the University of Butzow after its demise. It remains there to this day. Tychsen also collected Arabic coins and is considered the founding father of Islamic numismatics.[41] Salomonsen also mentions his acquaintance with a man named Mussafia[42] and his children, and how he enjoys spending time with them. Mussafia praised Tychsen and recalled something he had written on Tychsen’s behalf. He also possessed a work of Tychsen. Tychsen delighted in his name and reputation being spread throughout the Jewish community.

In sum, “Rabbi” Tychsen appears to have put his rabbinic degree to good use, at least from his perspective, cultivating an extremely devoted, loyal, and admiring, not to mention highly educated congregation. On the surface, he would be the envy of any modern rabbi, though much complexity lies beneath. While we did not focus on his proselytizing endeavors in this essay, perhaps this is one reason why Tychsen still remains to this day the only non-Jew to have received a form of rabbinic ordination. While Tychsen’s contributions to academia are vast, his tenure at the University of Butzow and his relationship with the Jewish students there represents one of the most unique, if lesser known, chapters in Jewish medical history. With the opening of the Rostock digital archives treasure trove we will certainly see further exploration of this topic.

[10] The University of Butzow was an offshoot of the University of Rostock and later recombined with Rostock upon its demise. In addition, in 1817, Rostock University acquired the private library, including the manuscript legacy, of Tychsen, which included his significant Judaica and Hebraica collection. Over the last few years, the University of Rostock has devoted research efforts to explore the history of the Jewish students at the university with particular focus on their relationship with Tychsen. See Gisela Boeck und Hans-Uwe Lammel, eds., Jüdische kulturelle und religiöse Einflüsse auf die Stadt Rostock und ihre Universität (Jewish cultural and religious influences on the city of Rostock and its university) (Rostocker Studien zur Universitätsgeschichte, Band 28: Rostock 2014); Rafael Arnold, et. al., eds., Der Rostocker Gelehrte Oluf Gerhard Tychsen (1734-1815) und seine Internationalen Netzwerke (Wehrhahn Verlag, 2019). In the latter volume, see especially, Malgorzata Anna Maksymiak and Hans-Uwe Lammel, “Die Bützower Jüdischen Doctores Medicinae und der Orientalist O. G. Tychsen,” 115-133. I thank Malgorzata Maksymiak for her assistance and for providing me access to the Tychsen archives.

[12] Nimrod Zinger notes that the universities under Protestant auspices, in particular those affiliated with the Pietistic Movement, were more inclined to admit Jews, as they were interested in the possibility of converting them. He mentions as examples Yitzhak Isaac Wallich and his close relationship with Professor Hoffman at Halle, and that the student Avraham Hyman was admitted to Geissen with the intervention of the head of faculty, who was a Pietist. See his Ba’al Shem vihaRofeh (Haifa University, 2017), 263. Tychsen would certainly align with this theory.

[32] Strelitz, also known as Levin Hirsch Levi, lived in Altstrelitz and authored a treatise on resurrection (http://rosdok.uni-rostock.de/resolve/id/rosdok_document_0000014475) which was translated into German by Tychsen under the title,”Die Auferstehung der Todten aus dem Gesetze Mosis Bewiesen,” (1766) (http://rosdok.uni-rostock.de/resolve/id/rosdok_document_0000014215). Strelitz later became rabbi of Birnbaum, and then the first rabbi of Stockholm and Chief Rabbi of Sweden. The Jewish community of Stockholm had been founded only a few years before his arrival by Aron Isak, the sponsor of Markus Moses, Levi’s brother-in-law, and the shadchan for Moses and Levi’s sister.

[33] Markus Moses (1764), Israel Joseph Meyer (1765), Justus Zadig de Meza, Isaac Heinrich Salomonsen (1783),Wolff Levinsohn (1783), Abraham Levin Spira (? Benjamin Levin, 1773), Simon Marcus (1771) and Moses Marcus(1785, son of Markus Moses). All of them-with one exception-received their doctorate in medicine in the twenty-nine years of existence of the University of Bützow.See Maksymiak,op.cit., which also addresses the emotional aspect of the ties of Tychsen with his students.

Note that word “Judeus” appears after both of their names. It was common to identify students as Jews in university archives. For example, starting in the 1500s, Jewish students at the University of Padua were identified as“Hebrei.” There does not appear to have been any anti-Semitic associations with this identifier.

The letter was not published with the dissertation.

[36] Tychsen appears to make disparaging remarks against the work Shevilei Emunah, by Meir Aldabi. This work,written in the fourteenth century, was a primary reference on medicine in rabbinic literature for many centuries.
