Johann Wolfgang Goethe* (1749–1832) believed that in 1784 he demonstrated the presence of the intermaxillary (premaxillary) bone in man, and that after a certain amount of opposition professional anatomists accepted his findings. This paper tries to show what the anatomical facts are, what it was that Goethe discovered, how his beliefs about his contribution and influence arose, and how his discovery is related to his general scientific aims and methods.
* Goethe is quoted from the Weimar edn. Pt. II, containing his scientific writings in 13 vols. Goethes Werke, hrsg. im Auftrage der Grossherzogin Sophie von Sachsen, II Abtheilung (Weimar, 1890–1904), hereinafter designated WA.
1 It was because the upper incisors are always situated in the premaxilla that Albrecht von Haller (1708–1777) named it the os incivisum. See his Bibliotheka Anatomica (London, 1748), i, 177. But Blumenbach considered the name os intermaxillare preferable, since the bone may be present even though the upper incisors are absent, as in cattle, the elephant, and the two-horned African rhinocerus.

In my account I have stressed the work of Vesalius and Albinus because it was known to Goethe when he wrote his paper; and also that of Vicq d'Azyr, who linked his views on the premaxilla with his idea of the unity of nature. This does not emerge from the surveys of Disselhorst (who makes no mention of Vicq d'Azyr) and Leuckart, although it is briefly stated by Russell, E.

According to Victor Franz, “on” means Goethe, of whose discovery of the bone in the walrus Vicq d'Azyr had been informed by letter from Camper.

11 Bd. I (Weimar, 1803), piate VI, figs. 3 and 28. Kohlbrugge, J. H. F. “Historischkritische Studien über Goethe als Naturforscher”, Zoolog. Annalen, v, (1913), 92Google Scholar, complains that, in deference to Goethe's views Loder has drawn the suture in Fig. 3 more distinctly than it ever normally appears. But Professor J. T. Aitken of London University has kindly shown me a standard teaching skull in which the suture line can be seen exactly as it is in Loder's drawing. Kohlbrugge also alleges that Fig. 28 is an embryonic form, that Loder never depicts embryos except in his drawings of the upper jaw, and that the purpose of such deviation from his normal practice was to indulge in some special pleading for the theory of his famous pupil. But in fact Fig. 28 is not drawn from an embryo, nor is it true that the only figures in the Plate that depict upper jaws (some show the embryonic condition of e.g. the mandible). In his animus against “incense bearers” (p. 104) who inflate the importance of Goethe's scientific work, Kohlbrugge mars his excellent monograph (to which I am deeply indebted) with a contrary exaggeration.

15 Blumenbach, for instance, expressly says that the intermaxillary bone is “in all [animals possessing it] distinguished by its own sutures from the neighbouring bones of the skull”. These sutures, he adds, include the facial one (Eng. trans, cit. (1), 176). Camper had assigned the bone to the orang and denied it to man specifically on the evidence of the facial suture. He wrote that the orang's “upper jaw is divided into two, so that a suture runs from the nasal cavity to between the canine and incisor tooth, as is the case with all apes, dogs, cats, lions and ruminants, even though the latter have no upper incisors”. He added that this division of the upper jaw suffices to class the orang among the quadrumana, for “I possess in my collection skulls of Negroes, Hottentots, Chinese and new-born and unborn European children, and have never seen in them any trace of this division”.

16 Having referred to the passages from Blumenbach and Camper quoted in (15), Goethe makes this statement while conceding the absence of the facial suture in man. He correlates its absence with the facial angle, saying that while the premaxilla is “pushed so far to the fore in animals, it is reduced in man to very small proportions. If one studies the skull of a child or of an embryo one will see how the teeth in their growth exert such a force on these parts and subject the bone fabric to such tension that nature has to exert all her strength to keep these parts in intimate union. Contrast this with an animal's skull, where the incisors are so far forwards that their pressure—either on each other or on the canine tooth—is not so strong”. Op. cit. (9), 101.Google Scholar

24 We saw above that in the and edn. of his De generis humani varietate he held that the bone is present in all apes but absent from man, the elephant, the ant-eater and the dolphin. In the 3rd edn. of 1795 he drops the denial concerning the last three of these mammals, says that whether it is present in all apes requires further investigation, but still affirms its absence from man (Eng. trans, cit. (1) 176). In his Handbuch der vergleichenden Anatomie (Göttingen, 1805), 22Google Scholar, he again says that man has all his upper teeth in the maxilla in contrast to most other mammals. He adheres to this position in the 3rd edn. of this work (Göttingen, 1824), saying (p. 22) that in man the two bones of the upper jaw abut against each other anteriorly to form a nasal spine, whereas in “other mammals” they are separated by a pair of intermaxillary bones wedged between them. By this date Goethe's paper had been published, and Blumenbach added in a note (to p. 24) that Goethe has shown “to what extent the [palatal] suture demarks what must be regarded as a rudiment of an intermaxillary bone”. The statement by Kiesselbach, A. (“Goethes Zwischenkieferstudien”, Medizinische Monatsschrift, ii (1948), 430)Google Scholar that Blumenbach changed his ground and accepted Goethe's view in this 3rd edn. is not correct. As late as 1830 (in his Handbuch der Naturgeschichte, Göttingen, 44n) Blumenbach referred to his words of 1795 as representing his opinion.

Thus even Leuckart, , op. cit. (3), 11Google Scholar, gives the extracts as the work of Goethe, and many writers have inferred from them that Goethe dissected embryos!

Abel noted that the fossil record and the idea of evolution—the former not available to Goethe, and the latter unimportant to his mind—have only recently enabled us to form a tolerably clear idea of a primitive reptile, bird or mammal; and that Goethe's quest for an archetype which should represent all vertebrate forms was thus necessarily unsuccessful. He also tells of Goethe's attempts (still to be seen in the Weimar museum) to homologize the skeletons of birds and man, and says they are “in some ways reminiscent of the ghostly visions of St. Antony”. “Goethe und die Biologie”, Biologia Generalis, ix (1932), 18.Google Scholar

37 Cuvier met thinking of this kind in the writings of the German “Naturphilosophen”, and answered it effectively even without disputing its teleological premiss. He “replied that nature, meaning of course the creative hand behind nature, was free to produce whatever was necessary for die specific needs of each individual, and if this entailed the violation of a supposed unity of organic nature, then so much the worse for the latter”.

47 Op. cit. (18), 17–18.Google Scholar Sir Richard Owen, the last great pre-Darwinian, reasoned on remarkably similar lines in his On the Nature of the Limbs (London, 1849), 85–86, where he argued that nature produced animal forms from an archetypal idea, and that those parts of animals which appear to have been “made in vain” are in fact illustrations of the design manifested in the archetype. On the other hand, the opponents of the archetype theory had no sympathy with Goethe's principle of compensation. Thus T. Magdeleine de Saint-Agy criticized it sharply in Cuvier, 's Histoire des sciences naturelles (Paris, 1845), v, 318Google Scholar (written to complete the work after Cuvier's death), saying that, if Goethe were right, ant-bears, which are without teeth, ought to have horns.
