Isidore Geoffroy Saint-Hilaire (1805 –1861) was a French zoologist, born in Paris, and an authority on deviation from normal structure. He coined the term ethology.

In his earlier years he showed an aptitude for mathematics, but eventually he devoted himself to the study of natural history and of medicine, and in 1824 he was appointed assistant naturalist to his father.

In 1832-1837 he published his great teratological work, Histoire générale et particulière des anomalies de l’organisation chez l’homme et les animaux.

He taught zoology at the Athne, and teratology at the Ecole pratique. He was elected a member of the French Academy of Sciences in 1833, was in 1837 appointed to act as deputy for his father at the faculty of sciences in Paris. He eventually became professor of zoology at the faculty of sciences (1850). In 1854 he founded the Acclimatization Society of Paris, of which he was president.

Besides the above-mentioned work, he wrote:

• Essais de zoologie generale (1841);
• Vie Etienne Geoffroy Saint-Hilaire (1847);
• Acclimatation et domestication des animaux utiles (1849);
• Lettres sur les substances alimentaires et particulièrement sur la viande de cheval (1856);
• Histoire naturelle générale des règnes organiques (3 vols., 1854-1862)
