'''Baron Georges Léopold Chrétien Frédéric Dagobert Cuvier''' ([[August 23]] [[1769]]–[[May 13]], [[1832]]) was a [[France|French]] [[natural history|naturalist]] and [[zoology|zoologist]]. He was the elder brother of [[Frédéric Cuvier]] (1773–1838), also a naturalist. He was a major figure in scientific circles in Paris during the early 19th century, and was instrumental in establishing the fields of comparative [[anatomy]] and [[paleontology]] by comparing living animals with fossils. He is well known for establishing that [[extinction]] was a fact, being the most influential proponent of [[catastrophism]] in geology in the early 19th century, and opposing early evolutionary theories. His most famous work is the ''Règne animal distribué d'après son organisation'' ([[1817]]; translated into English as ''The Animal Kingdom''). He died in [[Paris]] of [[cholera]].
==Life and scientific career==
[[Image:Vincentwfa.jpg|left|thumb|Portrait by [[Francois Andre Vincent]], [[Whitfield Fine Art]]]]
Cuvier was born at [[Montbéliard]] (then Mömpelgard in the duchy of [[Württemberg]]) under the name of '''Johann Leopold Nicolaus Friedrich Kuefer''' ([[:de:Küfer|Küfer]] is German for [[cooper (profession)|cooper]]), the son of a retired officer on half-pay belonging to a [[Protestant]] family which had emigrated from the [[Jura mountains]] on the French-Swiss border as a consequence of religious persecution.
The family followed the Lutheran tradition of work and religion. Early on, Georges Cuvier was given the works of [[Carolus Linnaeus|Linnaeus]] and [[Georges-Louis Leclerc, Comte de Buffon|Buffon]]. Therefore it is not surprising that he showed a bent towards the investigation of natural phenomena. He was also noted for his studious habits and marvelous memory.
After spending four years at the [[Karlsschule]] in [[Stuttgart]], where he received a pragmatic German education, he accepted the position of tutor in the cultivated family of the [[Comte d'Héricy]] in Normandy, who were in the habit of spending the summer near [[Fécamp]]. It thus came about that he made the acquaintance of the agriculturist [[A. H. Tessier]], who was then living at Fécamp, and who wrote strongly in favour of his protégé to his friends in [[Paris]] — with the result that Cuvier, after corresponding with the well-known naturalist [[Étienne Geoffroy Saint-Hilaire]], was appointed in 1795, at the age of 26, as assistant to the professor of [[comparative anatomy]] at the ''[[Muséum National d'Histoire Naturelle]]''.
[[Image:Cuvier elephant jaw.jpg|thumb|illustration of an Indian elephant jaw and a mammoth jaw from Cuvier's 1796 paper on living and fossil elephants]]
The [[Institut de France]] was founded in the same year, and he was elected a member of its [[French Academy of Sciences|Academy of Sciences]]. In 1796 he began to lecture at the ''[[École Centrale du Pantheon]]'', and at the opening of the National Institute in April, he read his first palaeontological paper, which was subsequently published in 1800 under the title ''Mémoires sur les espèces d'éléphants vivants et fossiles''. In this paper he analyzed skeletal remains of Indian and African [[elephant]]s as well as [[mammoth]] [[fossil]]s, and a fossil skeleton known at that time as the 'Ohio animal'. Cuvier's analysis established, for the first time, the fact that African and Indian elephants were different species and that mammoths were not the same species as either African or Indian elephants and therefore must be [[extinct]]. He further stated that the 'Ohio animal' represented another extinct species that was even more different from living elephants than mammoths were. Years later, in 1806, he would return to the 'Ohio animal' in another paper and give it the name [[mastodon]].
In his 2nd paper in the year 1796, he would describe and analyze a large skeleton found in [[Paraguay]], which he would name [[megatherium]]. He concluded that this skeleton represented yet another extinct animal and, by comparing its skull with living species of tree dwelling sloths, that it was a kind of ground dwelling [[giant sloth]]. Together these two 1796 papers were a landmark event in the [[history of paleontology]] and in the development of [[comparative anatomy]] as well. They also greatly enhanced Cuvier's personal reputation, and they essentially ended what had been a long running debate about the reality of [[extinction]].
In 1799 he succeeded [[Louis-Jean-Marie Daubenton|Daubenton]] as professor of natural history in the ''[[College de France]]''. In 1802 he became titular professor at the [[Jardin des Plantes]]; and in the same year he was appointed commissary of the Institute to accompany the inspectors general of public instruction. In this latter capacity he visited the south of France; but in the early part of 1803, he was chosen Permanent Secretary of the Department of Physical Sciences of the Academy, and he consequently abandoned the earlier appointment and returned to Paris. In 1806, he became a foreign member of the [[Royal Society]].
He now devoted himself more especially to three lines of inquiry: (i) the structure and classification of the Mollusca; (ii) the comparative anatomy and systematic arrangement of the fishes; (iii) fossil mammals and reptiles and, secondarily, the [[osteology]] of living forms belonging to the same groups.
According to Sander Gilman's essay "Black Bodies, White Bodies: Toward an Iconography of Female Sexuality in Late Nineteenth-Century Art, Medicine, and Literature," when the deceased [[Saartjie Baartman]] (1789-1815), the so-called "Hottentot Venus," was exhibited in Paris after being displayed to the curiosity of the public in London, Cuvier and others scientists examined her. Georges Curvier presented Baartman's dissected labia before the Academie Royale de Medecine, in order to allow them "to see the nature of the labia." Curvier and his contemporaries concluded that Baartman's genitalia was physical proof of the African women's "primitive sexual appetite." Baartman's genitalia continued to be exhibited at La Musée de l'Homme, the institution to which Curvier belonged, long after her death.
In 1821, Cuvier made what has been called his "Rash [[Dictum]]": he remarked that it was unlikely that any large animal remained undiscovered. Many such discoveries have been made since Cuvier's statement.
==Scientific ideas and their impact==
===Extinction===
At the time Cuvier presented his 1796 paper on living and fossil elephants, it was still widely believed that no species of animal had ever become extinct, because God's creation had been perfect. Authorities such as Buffon had claimed that fossils found in Europe of animals such as the [[wooly rhinoceros]] and mammoth were remains of animals still living in the tropics (ie [[rhinoceros]] and [[elephants]]), which had shifted out of Europe and Asia as the earth became cooler. Cuvier's early work demonstrated conclusively that this was not the case.<ref> Rudwick, ''Georges Cuvier, Fossil Bones, and Geological Catastrophes'' pp 22-24. </ref>
===Catastrophism===
Cuvier came to believe that most if not all the animal fossils he examined were remains of species that were now extinct. Near the end of his 1796 paper on living and fossil elephants he said:
:''All of these facts, consistent among themselves, and not opposed by any report, seem to me to prove the existence of a world previous to ours, destroyed by some kind of catastrophe.''
This led Cuvier to become an active proponent of the geological school of thought called [[catastrophism]] that maintained that many of the geological features of the earth and the past history of life could be explained by catastrophic events that had caused the extinction of many species of animals. Over the course of his career Cuvier came to believe that there had not been a single catastrophe but several, resulting in a succession of different faunas. He wrote about these ideas many times, in particular he discussed them in great detail in the preliminary discourse (introduction) to a collection of his papers, ''Recherches sur les ossemens fossiles de quadrupèdes'', on [[quadruped]] fossils published in 1812. The 'Preliminary Discourse' became very well known and unauthorized (and in the case of English not entirely accurate) translations were made into English, German and Italian. In 1826 Cuvier would publish a revised version under the name ''Discours sur les révolutions de la surface du globe''.
After Cuvier's death the catastrophic school of geological thought lost ground to [[uniformitarianism (science)|uniformitarianism]], as championed by [[Charles Lyell]] and others, which claimed that the geological features of the earth were best explained by currently observable forces, such as erosion and volcanism, acting gradually over an extended period of time. However, the increasing interest in the topic of [[mass extinction]] starting in the late 20th century has led to a resurgence of interest among historians of science and other scholars in this aspect of Cuvier's work.
===Stratigraphy===
Cuvier collaborated for several years with [[Alexandre Brongniart]], an instructor at the Paris mining school, to produce a monograph on the geology of the region around Paris. They published a preliminary version in 1808 and the final version was published in 1811. In this monograph they identified charateristic fossils of different rock layers that they used to analyze the geological column, the ordered layers of sedimentary rock, of the Paris basin. They concluded that the layers had been laid down over an extended period during which there clearly had been [[faunal succession]] and that the area had been submerged under sea water at times and at other times under fresh water. Along with [[William Smith (geologist)|William Smith]]'s work during the same period on a geological map of England, which also used characteristic fossils and the principle of faunal succession to correlate layers of sedimentary rock, the monograph helped establish the scientific discipline of [[stratigraphy]]. It was a major development in the [[history of paleontology]] and the [[history of geology]].<ref> Rudwick, ''Georges Cuvier Fossil Bones and Geological Catastrophes'' pp.129-133</ref>
===Age of reptiles===
In 1800, Cuvier was the first to correctly identify in print, working only from a drawing, a fossil found in Bavaria as a small flying reptile<ref name="cuvier1801">Cuvier, G. (1801). [Reptile volant]. In: Extrait d’un ouvrage sur les espèces de quadrupèdes dont on a trouvé les ossemens dans l’intérieur de la terre. ''Journal de Physique, de Chimie et d’Histoire Naturelle'', '''52''': 253–267.</ref>, which he named the ''Ptero-Dactyle'' in 1809<ref name="cuvier1809">Cuvier, G. (1809). "Mémoire sur le squelette fossile d’un reptile volant des environs d’Aichstedt, que quelques naturalistes ont pris pour un oiseau, et dont nous formons un genre de Sauriens, sous le nom de Ptero-Dactyle." ''Annales du Muséum national d’Histoire Naturelle, Paris'', '''13''': 424–437.</ref> (later Latinized as ''[[Pterodactylus|Pterodactylus antiquus]]'')--the first known member of the diverse order of [[pterosaur]]s. In 1808 Cuvier identified a fossil found in [[Maastricht]] as giant marine lizard, which he named ''[[Mosasaurus]]'', the first known [[mosasaur]]. Cuvier speculated that there had been a time when [[reptile]]s rather than [[mammal]]s had been the dominant fauna.<ref> Rudwick p 158 </ref> This speculation was confirmed over the next two decades by a series of spectacular finds, mostly by English geologists and fossil collectors, who found and desribed the first [[ichthyosaur]]s, [[plesiosaur]]s, and [[dinosaur]]s.
===Principle of correlation of parts===
In a 1798 paper on the fossil remains of an animal found in some plaster quarries near Paris Cuvier wrote:
:'' Today comparative anatomy has reached such a point of perfection that, after inspecting a single bone, one can often determine the class, and sometimes even the genus of the animal to which it belonged, above all if that bone belonged to the head or the limbs. ... This is because the number, direction, and shape of the bones that compose each part of an animal's body are always in a necessary relation to all the other parts, in such a way that - up to a point - one can infer the whole from any one of them and vice versa.''
This idea is sometimes referred to as 'Cuvier's principle of correlation of parts', and while Cuvier's description may somewhat exaggerate its power, the basic concept is central to comparative anatomy and paleontology.
=== Opposition to evolution ===
Cuvier was highly critical of evolutionary theories proposed by his contemporaries [[Lamarck]] and [[Etienne Geoffroy Saint-Hilaire|Geoffroy Saint-Hilaire]]. He was skeptical of the mechanisms of change that they proposed and his commitment to the principle of correlation of parts caused him to doubt that any mechanism could ever significantly modify any part of an animal in isolation from all the other parts, without rendering the animal unable to survive. In his ''Elegy of Lamarck'', Cuvier noted that Lamarck’s theory rested on two shaky assumptions — that a nervous fluid exists with the power to mold organs and that use and disuse can effect changes in an organism’s body type:
:"[Lamarck’s evolution] rested on two arbitrary suppositions; the one, that it is the seminal vapor which organizes the embryo; the other, that efforts and desires may engender organs. A system established on such foundations may amuse the imagination of a poet; a metaphysician may derive from it an entirely new series of systems; but it cannot for a moment bear the examination of any one who has dissected a hand, a viscus, or even a feather."
He also pointed out that Napoleon's expedition to Egypt had retrieved animals mummified thousands of years previously that seemed no different from their modern counterparts.<ref> Zimmer, ''Evolution: the triumph of an idea'' pp 19 </ref> "Certainly," Cuvier wrote, "one cannot detect any greater difference between these creatures and those we see, than between the human mummies and the skeletons of present-day men."<ref>Rudwick, ''Georges Cuvier, Fossil Bones, and Geological Catastrophes'', pp 229</ref> Lamarck dismissed this conclusion, arguing that evolution happened much too slowly to be observed over just a few thousand years. Cuvier, however, in turn criticized how Lamarck and other naturalists conveniently introduced hundreds of thousands of years "with a stroke of a pen" to uphold their theory. Instead, he argued that one can only judge what a long time would produce by multiplying what a lesser time produces. Since a lesser time produced no organic changes, neither, probably, would a much longer time.<ref>Rudwick, ''Georges Cuvier, Fossil Bones, and Geological Catastrophes'', pp 228-229</ref>
The harshness of his criticism and the strength of his reputation continued to discourage naturalists from speculating about the transmutation of species, right up until [[Charles Darwin|Darwin]] published ''[[The Origin of Species]]'' more than two decades after Cuvier's death.<ref> Larson, ''Evolution: the history of a scientific theory'' pp 9-10 </ref>
==Chief scientific work==
===On comparative anatomy and classification===
In 1798 Cuvier published his first independent work, the ''Tableau élémentaire de l'Histoire naturelle des animaux'', which was an abridgment of his course of lectures at the École du Pantheon, and may be regarded as the foundation and first statement of his natural classification of the animal kingdom.
In 1800 he published the ''Leçons d'anatomie comparée'', assisted by [[André Marie Constant Duméril|A. M. C. Duméril]] for the first two volumes and [[Georges Louis Duvernoy]] for the three later ones.
===On molluscs===
Cuvier's papers on the Mollusca began appearing as early as 1792, but most of his memoirs on this branch were published in the ''[[Annales du museum]]'' between 1802 and 1815; they were subsequently collected as ''Mémoires pour servir de l'histoire et a l'anatomie des mollusques'', published in one volume at Paris in 1817.
===On fish===
Cuvier's researches on [[fish]], begun in 1801, finally culminated in the publication of the ''Histoire naturelle des poissons'', which contained descriptions of 5000 species of fishes, and was the joint production of Cuvier and [[Valenciennes|A. Valenciennes]]. Cuvier's work on this project extended over the years 1828–1831.
===On palaeontology and osteology===
In this field Cuvier published a long list of memoirs, partly relating to the bones of extinct animals, and partly detailing the results of observations on the skeletons of living animals, specially examined with a view of throwing light upon the structure and affinities of the fossil forms.
Among living forms he published papers relating to the osteology of the ''[[Rhinoceros]] Indicus'', the [[tapir]], ''[[Hyrax]] Capensis'', the [[hippopotamus]], the [[sloth]]s, the [[manatee]], etc.
He produced an even larger body of work on fossils, dealing with the extinct mammals of the [[Eocene]] beds of [[Montmartre]], the fossil species of [[hippopotamus]], a [[marsupial]] (which he called ''Didelphys gypsorum''), the [[Megalonyx]], the [[Megatherium]], the cave-[[hyena]], the [[pterodactylus|pterodactyl]], the extinct species of [[rhinoceros]], the [[cave bear]], the [[mastodon]], the extinct species of [[elephant]], [[fossil]] species of manatee and [[Seal (mammal)|seals]], fossil forms of [[crocodile|crocodilians]], [[chelonian]]s, fishes, [[bird]]s, etc. The department of palaeontology dealing with the [[Mammal]]ia may be said to have been essentially created and established by Cuvier.
The results of Cuvier's principal palaeontological and geological investigations were ultimately given to the world in the form of two separate works: ''Recherches sur les ossemens fossiles de quadrupèdes'' (Paris, 1812; later editions in 1821 and 1825); and ''Discours sur les revolutions de la surface du globe'' (Paris, 1825). In this latter work he expounded a scientific theory of [[Catastrophism]].
===''The Animal Kingdom''===
None of Cuvier's works attained a higher reputation than his ''Règne Animal distribué d'après son Organisation pour servir de base à l'Histoire Naturelle des Animaux et d'Introduction à l'Anatomie Comparée'', the first edition of which appeared in four octavo volumes in 1817, and the second in five volumes in 1829–1830. In this classic work Cuvier embodied the results of the whole of his previous researches on the structure of living and fossil animals. The whole of the work was his own, with the exception of the section on ''[[Insect]]a'', in which he was assisted by his friend [[Pierre André Latreille|Latreille]]. It was translated into English many times, often with substantial notes and supplementary material updating the book in accordance with the expansion of knowledge.

==Official and public work==
Apart from his own original investigations in zoology and [[paleontology]] Cuvier carried out a vast amount of work as perpetual secretary of the National Institute, and as an official connected with public education generally; and much of this work appeared ultimately in a published form. Thus, in 1808 he was placed by [[Napoleon I of France|Napoleon]] upon the council of the [[Imperial University]], and in this capacity he presided (in the years 1809, 1811 and 1813) over commissions charged to examine the state of the higher educational establishments in the districts beyond the [[Alps]] and the [[Rhine]] which had been annexed to France, and to report upon the means by which these could be affiliated with the central university. Three separate reports on this subject were published by him.
In his capacity, again, of perpetual secretary of the Institute, he not only prepared a number of ''[[éloges historiques]]'' on deceased members of the Academy of Sciences, but he was the author of a number of reports on the history of the physical and natural sciences, the most important of these being the ''Rapport historique sur le progrès des sciences physiques depuis 1789'', published in 1810.
Prior to the fall of Napoleon (1814) he had been admitted to the council of state, and his position remained unaffected by the restoration of the [[Bourbon house|Bourbons]]. He was elected chancellor of the university, in which capacity he acted as interim president of the council of public instruction, whilst he also, as a [[Lutheran]], superintended the faculty of Protestant theology. In 1819 he was appointed president of the committee of the interior, and retained the office until his death.
In 1826 he was made grand officer of the [[Légion d'honneur|Legion of Honour]]; and in 1831 he was raised by [[Louis-Philippe of France|Louis Philippe]] to the rank of [[peer of France]], and was subsequently appointed president of the council of state. Member of the [[Doctrinaires]], he was nominated to the ministry of the interior in the beginning of 1832.
==Animals named after Cuvier==
Cuvier is commemorated in the naming of many animals; they include [[Cuvier's beaked whale]], [[Cuvier's Gazelle]], [[White-throated toucan|Cuvier's toucan]], [[Gray bichir|Cuvier's Bichir]], ''Galeocerdo cuvieri'' ([[tiger shark]]), and ''[[Anolis|Anolis cuvieri]]'', a lizard from Puerto Rico. There are also some extinct animals named after Cuvier, such as the South American giant sloth ''Catonyx cuvieri''.
