The postcard


Original, German, text

English translation

The Secretariat of

The postcard was mailed on November 1st, 1920 by the well-known German paleontologist Wilhelm von Branca from Munich to the Prussian Academy of Sciences in Berlin to notify the Academy of Branca’s new permanent address following his retirement and relocation from Berlin to Munich.
The postcard itself is also historically significant as a piece of German postal stationery from the transitional period following World War I. Produced in 1920, it features a Bavarian definitive stamp design that was overprinted with “Deutsches Reich” to mark the integration of Bavaria's autonomous postal administration into the national Reichspost.
The pre-printed stamp reproduces the 30 Pfennig definitive stamp of Bavaria (Bayern). The number 20 on the bottom right corner of the postcard indicates the year of manufacture - 1920.

The Kingdom of Bavaria came to an end in November 1918, when the German Revolution forced King Ludwig III to abdicate and the monarchy collapsed.
Bavaria subsequently became part of the Weimar Republic, which replaced the imperial system after the fall of the German Empire (Deutsches Reich) at the end of World War I.
In historical usage, the term “German Empire” ( “Deutsches Reich”) is sometimes loosely extended into the early Weimar period, although politically the monarchy ended in 1918 and the republic formally succeeded it.

After retiring from his academic career in Berlin on April 1st, 1917, von Branca relocated to Munich in 1918, where he lived until his death in 1928.
During the final years of his career, Branca increasingly suffered from health problems, particularly gout, and frequently sought relief in health spas and climatic resorts in southern Germany, especially in the spa regions of Baden and the Alpine foothills. The search for a milder climate appears to have been an important factor in his decision to leave Berlin and settle in southern Germany after retirement. The family initially considered relocating to Merano in northern Italy, but the plan failed when the Italian authorities refused to issue passports. Instead, the Brancas moved to Munich.

Munich was a natural choice for Branca. Besides offering a milder climate than Berlin, the city held long-standing personal and professional ties for him.
He had first lived in Munich between 1878 and 1880 while studying fossil collections with Karl Alfred von Zittel at the Bavarian State Collection, residing in the Maxvorstadt district on Türkenstraße and later on Arcisstraße. During this period, Wilhelm von Branca focused his studies almost exclusively on fossil cephalopods, particularly ammonites.
Although his subsequent professorship at the University of Tübingen from 1890 to 1895 took him away from Munich, his return to the city after retiring in 1917 allowed him to spend his final years in a familiar and culturally rich environment, close to his early scientific roots.

The Oktoberfest in Munich is the world’s largest beer festival and funfair, and celebrated its 200th anniversary in 2010. No specific historical record or diary entry is known to the author that confirms Wilhelm von Branca visited the Oktoberfest during his years in Munich. However, given the chronology of his life and the proximity of his residences to the festival grounds, it is highly probable that he attended the event at least once.

Finding permanent housing during the difficult postwar years proved challenging, so Wilhelm von Branca and his wife lived at several temporary addresses in Munich and elsewhere in Bavaria while searching for a location better suited to Branca’s health. Eventually, they settled permanently at Kurfürstenplatz 8, where Branca spent the remainder of his retirement while continuing to correspond with universities, academies, and scientific societies.

By 1920, the family was residing at Türkenstraße 104 in the Maxvorstadt district, near the Ludwig Maximilian University of Munich. As a long-standing member of the Prussian Academy of Sciences, von Branca continued to receive official correspondence and scholarly publications from Berlin.
He mailed this postcard on November 1st, 1920, to ensure that Academy correspondence would be redirected to his Munich residence.
Even during his retirement in Munich, von Branca remained scientifically active. In 1920 he published the article Einiges über das Werden des Menschengeschlechtes (“Some Remarks on the Development of Humankind”) in the journal Deutsche Revue, reflecting his continued interest in evolution and paleoanthropology.
Administrative records from 1925 show that his membership was formally reclassified as that of an External Member (Auswärtiges Mitglied) because he permanently resided outside Prussia in Bavaria. The Academy continued sending correspondence to his Munich address until his death in 1928.

Wilhelm von Branco / von Branca

Wilhelm von Branco (1844–1928) was one of Germany’s most influential paleontologists and geologists of the late 19th and early 20th centuries. Born as Wilhelm Branco in Potsdam, he studied geology and natural sciences at the universities of Halle and Heidelberg, and completed further academic training in Rome and Berlin before beginning an academic career.
Branco became especially well known for his research on fossil cephalopods, dinosaurs, and the geological structure of volcanic regions in Europe and the Middle East. He held professorships at several German universities before becoming professor of geology and director of the Geological-Paleontological Institute and Museum at the University of Berlin, later associated with the Museum für Naturkunde.

In 1895, while serving as a professor in the Kingdom of Württemberg, he was ennobled by King Wilhelm II and acquired the noble predicate "von", becoming von Branco.
He continued to teach in Württemberg for several more years before moving to Berlin (Kingdom of Prussia) in 1899, where he stayed until the end of his career in 1917. However, in Prussia his Württemberg title was not fully recognized for official purposes. Prussian authorities generally distinguished between hereditary nobility and personal ennoblements granted by other German states, limiting the official status of such titles. This situation appears to have caused considerable frustration for Branca during his years in Berlin.

In 1907, after establishing close ties with the Italian branch of his family, he changed his surname to von Branca, reflecting the original Italian spelling of the family name. However, he continued to use the name von Branco in many of his scientific publications.

Today, von Branca is best remembered for overseeing and promoting the famous Tendaguru Expedition (1909–1913) in German East Africa (modern Tanzania), one of the largest dinosaur excavations ever undertaken by German paleontologists. The expedition uncovered spectacular Jurassic dinosaur fossils, including remains of Giraffatitan brancai (originally classified as Brachiosaurus brancai), which was named in his honour. Many of these fossils remain among the most important exhibits in the Berlin natural history collections and were depicted on postage stamps.

Beyond his scientific research, Branca played a major role in shaping German paleontology during the Imperial and early Weimar periods. As professor of geology and director of the Geological-Paleontological Institute in Berlin, he helped transform the city into one of Europe’s leading centers for paleontological research in the early 20th century.
Von Branca strongly supported Darwinian evolution at a time when evolutionary ideas were still debated within parts of the German scientific community. He also encouraged large-scale interdisciplinary research that combined geology, paleontology, zoology, and comparative anatomy.

Von Branca was also influential as an academic organizer and mentor.
He trained a generation of German geologists and paleontologists who later occupied important university and museum positions throughout Germany. Through his publications, university teaching, museum administration, and membership in the Prussian Academy of Sciences, he helped shape the direction of German paleontology during a period when the discipline was becoming increasingly professionalized and internationally connected.

Even after his retirement in 1917 and the political collapse of Imperial Germany in 1918, von Branca remained an important figure within German scientific institutions during the early Weimar Republic. His continued correspondence with the Prussian Academy of Sciences demonstrates that he retained scholarly influence and institutional recognition until the end of his life.
