Étienne Geoffroy Saint-Hilaire
Étienne Geoffroy Saint-Hilaire (15 April 177219 June 1844) was a French naturalist who established the principle of "unity of composition". He was a colleague of Jean-Baptiste Lamarck and expanded and defended Lamarck's evolutionary theories. Geoffroy's scientific views had a transcendental flavor (unlike Lamarck's materialistic views) and were similar to those of German morphologists like Lorenz Oken. He believed in the underlying unity of organismal design, and the possibility of the transmutation of species in time, amassing evidence for his claims through research in comparative anatomy, paleontology, and embryology. He is considered as a predecessor of the evo-devo evolutionary concept. Life and early career Geoffroy was born at Étampes (in present-day Essonne), and studied at the Collège de Navarre, in Paris, where he studied natural philosophy under M. J. Brisson. He then attended the lectures of Daubenton at the College de France and Fourcroy at the Jardin de ...

Albert Geoffroy Saint-Hilaire
Albert Geoffroy Saint-Hilaire (December 2, 1835 – January 30, 1919) was a French zoologist who served as a director of the Jardin d'acclimatation du Bois de Boulogne in Paris from 1865 to 1893. He was the son of the zoologist Isidore Geoffroy Saint-Hilaire (1805-1861) and grandson of the naturalist Étienne Geoffroy Saint-Hilaire (1772-1844). Life and work Saint-Hilaire was born in Paris in a well-known family of zoologists. He graduated in 1855 and worked for his father and was involved in developing the Jardin d'acclimatation which had been founded by his father. In the 1860s it drew nearly a quarter million visitors a year. Albert became its director in 1865 at a time when its finance were very poor. He tried to convert the institution from a utilitarian one to a profit-seeking attraction. During the Paris Commune in 1870-71 the Jardin became home to 130,000 sheep and 20,000 cattle meant to feed Paris. The other animals were sent of Antwerp and Brussels by train and a few of ...
