Alcide D'Orbigny

Alcide Charles Victor Marie Dessalines d'Orbigny (6 September 1802 – 30 June 1857) was a French naturalist who made major contributions in many areas, including zoology (including malacology), palaeontology, geology, archaeology and anthropology.

D'Orbigny was born in Couëron ( Loire-Atlantique), the son of a ship's physician and amateur naturalist. The family moved to La Rochelle in 1820, where his interest in natural history was developed while studying the marine fauna and especially the microscopic creatures that he named "foraminiferans".

In Paris he became a disciple of the geologist Pierre Louis Antoine Cordier (1777–1861) and Georges Cuvier. All his life, he would follow the theory of Cuvier and stay opposed to Lamarckism.

South American era

D'Orbigny travelled on a mission for the Paris Museum, in South America between 1826 and 1833. He visited Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, Argentina, Paraguay, and Brazil, and returned to France with an enormous collection of more than 10,000 natural history specimens. He described part of his findings in ''La Relation du Voyage dans l'Amérique Méridionale pendant les annés 1826 à 1833'' (Paris, 1824–47, in 90 fascicles). The other specimens were described by zoologists at the museum.

His contemporary, Charles Darwin, arrived in South America in 1832, and on hearing that he had been preceded, grumbled that D'Orbigny had probably collected "the cream of all the good things". Darwin later called D'Orbigny's Voyage a "most important work". They went on to correspond, with D'Orbigny describing some of Darwin's specimens.

He was awarded the Gold Medal of the Société de Géographie of Paris in 1834. The South American Paleocene pantodont ''Alcidedorbignya'' was named in his honour.

1840 and later

In 1840, d'Orbigny started the methodical description of French fossils and published ''La Paléontologie Française'' (8 vols). In 1849 he published a closely related ''Prodrome de Paléontologie Stratigraphique'', intended as a "Preface to Stratigraphic Palaeontology", in which he described almost 18,000 species, and with biostratigraphical comparisons erected geological stages, the definitions of which rest on their stratotypes.

In 1853 he became professor of palaeontology at the Paris Muséum National d'Histoire Naturelle, publishing his ''Cours élémentaire'' that related paleontology to zoology, as a science independent of the uses made of it in stratigraphy. The chair of paleontology was created especially in his honor. The d'Orbigny collection is housed in the ''Salle d'Orbigny'' and is often visited by experts.

He described the geological timescales and defined numerous geological strata, still used today as chronostratigraphic reference such as Toarcian, Callovian, Oxfordian, Kimmeridgian, Aptian, Albian and Cenomanian. He died in the small town of Pierrefitte-sur-Seine, near Paris.

Catastrophism

D'Orbigny, a disciple of Georges Cuvier, was a notable advocate of catastrophism.

He recognized twenty-seven catastrophes in the fossil record. Singer, Charles Joseph. (1931). ''The Story of Living Things: A Short Account of the Evolution of the Biological Sciences''. Harper & Bros. p. 232 This became known as the "doctrine of successive creations". Prothero, Donald R. (2013). ''Bringing Fossils to Life: An Introduction to Paleobiology''. Columbia University Press. p. 223. He attempted to reconcile the fossil record with the Genesis creation narrative. Both uniformitarian geologists and theologians rejected his idea of successive creations.

Palaeontologist Carroll Lane Fenton has noted that his idea of twenty-seven world-wide creations was "absurd", even for creationists. L. Sprague de Camp has written that "Alcide d'Orbigny, carried the idea to absurdity. Dragging in the supernatural, d'Orbigny argued that, on twenty-seven separate occasions, God had wiped out all life on earth and started over with a whole new creation."
