Family background Johann Friedrich Blumenbach (May 11, 1752–January 22, 1840) came from a well-to-do family of academics and civil servants in Gotha, the capital of the small German duchy of Saxe-Gotha-Altenburg. His father, Johann Heinrich Blumenbach (1709–1787), was a professor at the Gotha grammar school, the Gymnasium illustre, and its prorector; his mother, Charlotte Eleonore Hedwig Blumenbach (1727–1794), was the daughter of Karl Franz Buddeus (1695–1753), vice-chancellor of the government of Saxe-Gotha, and the granddaughter of the Jena professor of theology Johann Franz Buddeus (1667–1729). Blumenbach had a sister (Charlotte Sophie Henriette, died 1802) and a brother (Friedrich Wilhelm Carl Ernst, died 1806). There were also family ties to another dynasty of scholars at Jena, the Walch family: Johann Georg Walch (1693–1775), a professor of theology at Jena, was the brother-in-law of Blumenbach’s maternal grandfather and therefore Blumenbach’s great-uncle. One of his sons, Johann Ernst Immanuel Walch (1725–1778), was Blumenbach’s teacher in natural history at Jena University, and another son, Christian Wilhelm Franz Walch (1726–1784), became professor of theology at Göttingen University in 1754. Blumenbach retained his close connection with Gotha in later life. He stayed there for fairly long visits once or twice a year and on these occasions was invited to the duke’s court. He corresponded with several members of the ducal family and with Gotha scientists, especially Franz Xaver von Zach, and contributed to scientific journals published there and to the Almanach de Gotha (Gothaischer Hofkalender). Toward the end of 1814, a breakup with the new duke of Gotha, August, occurred. Two years later, Blumenbach bought the house in Göttingen where he had been living since 1784 – an investment that involved the acquisition of the town’s citizenship. In 1779 Blumenbach married Louise Amalie Brandes (1752–1837), thus establishing family relations with influential circles at Göttingen University and in the administration of the Electorate of Hanover, the territory to which Göttingen belonged. Her father was Georg Friedrich Brandes (1709–1791), the Hanoverian state secretary for university affairs. Louise Amalie was also the sister-in-law of the classical scholar Christian Gottlob Heyne (1729–1812), the central figure of the academic scene at Göttingen, given his influence as director of the University Library and secretary of the Academy of Sciences.

Blumenbach and his wife had four children: Georg Heinrich Wilhelm (1780–1855), who later was a senior civil servant in Hanover and in 1818 married Helene Ludovike Friederike Henriette, née Cleve (1797–1875); Emma Marie Hedwig (1783–1819), who in 1807 married Carl Wilhelm Friedrich Theodor von Jasmund (1782–1847); Charlotte Friederike Adelheid (Adele) (1787–1837); and Carl Ludwig Edmund (1788–1814), lieutenant in the “King’s German Legion” and killed in the Battle of Toulouse.

Education and career From 1759 to 1769 Blumenbach attended the Gymnasium illustre at Gotha, afterwards studying medicine at Jena, the state university of the three Saxe-Ernestine duchies, one of which was Saxe-Gotha-Altenburg. In the autumn of 1772 he moved to Göttingen, where the lectures by Christian Wilhelm Büttner (1716–1801) inspired his dissertation De generis humani varietate nativa. When in 1773 Büttner’s vast natural history collections were purchased by the Hanoverian state in order to create an Academic Museum at Göttingen, Blumenbach was hired to catalogue them. In September 1775 he received his doctoral degree with Ernst Gottfried Baldinger (1738–1804) as his supervisor, and in February 1776 Blumenbach became associate professor of medicine, prosector, and sub-curator of the Academic Museum, the official director of which was Heyne. Having been appointed full professor in 1778 and member of the Göttingen Academy of Sciences in 1784, when still in his early thirties, Blumenbach’s position in academic Gööttingen was secure and settled, although in later years he was able to expand his influence (1792 member of the Faculty of Medicine; 1812 head of the Academic Museum; 1812 secretary of the Göttingen Academy of Sciences; 1816 “professor primarius” of the Faculty of Medicine).

The Göttingen naturalist Johann Christian Polycarp Erxleben (1744–1777) lived in this house since 1774. Blumenbach moved into this house in 1784 and bought it in 1816. The present-day name of the street is “Neustadt.” The historical buildings of this part of the town, including Blumenbach’s house, were demolished around 1970.

Blumenbach and Göttingen Like Christian Gottlob Heyne and Carl Friedrich Gauß, Blumenbach devoted his entire academic life to Göttingen University. For several decades his lectures on natural history attracted students from all over Europe and from a range of social strata. In return, the Georgia Augusta provided him with excellent working conditions, generous funding, and exceptional intellectual freedom to carry out research and make his ideas public by means of lecture courses and published writings. Although the scope of Blumenbach’s research was global, he never left Göttingen for long. Except for summer sojourns in nearby spas (Pyrmont; Driburg), excursions with students to the Harz Mountains, and visits to Gotha and Weimar (where he saw Johann Wolfgang von Goethe), he undertook only two major scientific journeys: to Switzerland (April–October 1783) and to London (November 1791–April 1792). The main purpose was to establish contact with scientific institutions and their leading representatives. Blumenbach enjoyed similar opportunities when in September 1807 he took part in a diplomatic mission to Paris on behalf of Göttingen, which at the time belonged to the Napoleonic satellite kingdom Westphalia (1807–1813). Because of his international reputation and diplomatic skill, Blumenbach, together with the Göttingen jurist and diplomat Georg Friedrich von Martens (1756–1821), was entrusted with pleading the case of his town and university when during the Napoleonic Wars the French army was closing in on Göttingen. Also, in October 1813, after Napoleon’s defeat in the Battle of Leipzig, Blumenbach’s ambassadorial expertise was called upon when he was sent to the temporary headquarters of the anti-Napoleonic coalition in Heiligenstadt in an effort to prevent military damage to his town and university. In recognition of Blumenbach’s services, the city in 1824 granted him a twenty-year exemption from all communal property taxes. Blumenbach is buried in Göttingen’s former Albani Cemetery (today Cheltenham Park). The grave still exists. (For details and reference see Biographical data.)

Blumenbach and the Göttingen Academy of Sciences Blumenbach’s career is closely connected with the Göttingen Academy of Sciences (at the time called “Society of Sciences”). His first publications were based on papers read at its 1773 and 1774 sessions when he was twenty-one and twenty-two years of age respectively, and before he had obtained his doctoral degree. In 1784, Blumenbach was elected a member of the Academy and from 1786 onward regularly contributed to its Commentationes. This outlet also served him as a publication platform for a long-term project in the field of physical anthropology, the Decades collectionis suae craniorum diversarum gentium illustratae, a series of seven papers with images and descriptions of human skulls from all over the world, published between 1790 and 1828. Additionally, Blumenbach wrote more than 400 articles for the Academy’s reviewing journal, the Göttingische gelehrte Anzeigen. The key position in the Academy during the eighteenth and early nineteenth centuries was the office of secretary. It was a permanent appointment, whereas the position of director rotated on an annual basis. When Heyne, who had been secretary for more than forty years, died in 1812, Blumenbach succeeded him and retained the post for the rest of his life, which earned him critcism in later years. However, the Academy profited from Blumenbach’s innumerable professional and private contacts with scholars and scientists, especially in the evolving field of the natural sciences, as well as with people in politics and society at large. By around 1820, he was a member of more than forty, and toward the end of his life some seventy academies and scientific societies in Europe and in the United States. More than 2,200 of the letters he wrote or received are known, documenting a network of correspondence that included the centers of the academic world of his time, like Paris and London, but also its outposts – for example, in Petropavlovsk on the Kamchatka Peninsula, in South Africa, and in Indonesia. On 31 October 1839, around three months before his death, Blumenbach asked to be relieved of this office due to his advanced age. However, the position was not formally re-assigned to another member of the Academy before his death. (For details and reference see Biographical data.)

Scientific collections Blumenbach explored the natural world primarily by collecting, not so much by traveling or experimenting in a laboratory. He gained access to nature on a global scale by bringing together a large collection of natural history specimens, requesting correspondents, colleagues, friends, and students to send him minerals, fossils, meteorites, anatomical specimens, cultural artifacts, and even living animals. Especially fruitful were Blumenbach’s contacts with London, the center of the British Empire, and with Saint Petersburg, from where the tsarist government organized the exploration of its territories in Central and Northern Asia, Siberia, and Alaska. Former students who set off on journeys of scientific exploration, among whom Alexander von Humboldt, Georg Heinrich von Langsdorff, and Maximilian zu Wied-Neuwied, contributed to his collections. Blumenbach not only enlarged the collections of the Academic Museum but also accumulated substantial private collections. Upon his death in 1840, these were bought for, and added to, the museum. Prominent among Blumenbach’s private objects of natural history was his collection of human skulls. When he died, it contained some 240 specimens, among these the skulls of pre-Columbian inhabitants of Peru, ancient Romans and Germans, artificially deformed skulls from Anatolia, and skulls from Polynesia, South Asia, and Australia. Blumenbach used them to validate his doctrine that all human “varieties” belong to a single biological species. Many of the objects studied by Blumenbach can be found in today’s research and teaching collections at Göttingen University.

Biographical studies Marx, Karl Friedrich Heinrich: Zum Andenken an Johann Friedrich Blumenbach: eine Gedächtniss-Rede gehalten in der Sitzung der Königlichen Societät der Wissenschaften den 8. Februar 1840; digitised version. Göttingen : Druck und Verlag der Dieterichschen Buchhandlung, 1840. – K. F. H. Marx (1796–1877) was Blumenbach’s physician and confidant. He probably had access to some of Blumenbach’s private papers, which he cites – alongside his personal recollections – in his obituary. The style of the „Gedächtniss-Rede“ is sometimes almost hagiographic. It is, however, important, because it has information about Blumenbach’s personality, which is not available elsewhere. Cf. also e.g. the short, critical account of Blumenbach as a person in the memoirs of the diplomat Piter Poel (1760–1837), who had no private or professional connection with Blumenbach: Bilder aus vergangener Zeit, nach Mittheilungen aus großentheils ungedruckten Familienpapieren. Erster Theil (1760–1787). Hamburg: Agentur des Rauhen Hauses, 1884, p. 267–270; digitised version. Marx’ “Gedächtniss-Rede” is also a document of the reception history of Blumenbach, showing the assessment of Blumenbach’s achievements around 1840. Thirty years later August Heinrich Rudolph Grisebach gave a far more critical assessment of Blumenbach’s scientific achievements and his – according to Grisebach partially unfavourable – role in the development of Göttingen university (“Blumenbach” in: Rocholl, Rudolf (Hg.): Göttinger Professoren: ein Beitrag zur deutschen Cultur- und Literärgeschichte in acht Vorträgen. Gotha: Perthes, 1872, pp. 139–165; digital copy). Cf. in contrast, for example, the relativisation of Grisebach’s assessments by the Göttingen librarian (and in later times race theorist) Ludwig Schemann (Schopenhauer-Briefe. Leipzig: Brockhaus, 1893, pp. 467–468; digital version), again twenty years later. Note: Schemann later became known as a racial theorist. When he wrote the remarks on Blumenbach quoted here, however, he (probably: still) counted it to his credit that “at the time when the Negroes and savages were still considered half animals, […] he also stated out loud that their physical abilities were not inferior to those of Europeans, that all inhabitants of the earth should be accorded equal rights and equal dignity.” Ehlers, Ernst: Göttinger Zoologen.
