Marie Jules César Savigny
|Died||5 October 1851 (aged 74)|
|Institutions||Muséum national d'histoire naturelle|
Savigny was born at Provins. In 1798 he travelled to Egypt with the Emperor Napoleon as part of the French scientific expedition to that country, and contributed to the publication of the findings of the expedition in 1809 (Description de l'Égypte; published more fully in 1822). He wrote about the fauna in the Mediterranean Sea and the Red Sea. He is also known for proposing a theory that the mouth-parts of insects are homologous with locomotory organs (e.g. legs).
Education and travel to Egypt
At age 16, Savigny traveled from his home of Provins, in the department of Seine et Marne, to Paris to finish his studies. Being very interested in botany, he worked at the Muséum national d'histoire naturelle with Jean-Baptiste Lamarck and Georges Cuvier. Cuvier suggested to Napoleon that the 21-year-old Savigny should follow him as zoologist to Egypt. Savigny became responsible for studying invertebrates, while Étienne Geoffroy Saint-Hilaire took care of the vertebrates. After returning to Paris, in 1802, Savigny started to work on the large collections from Egypt, producing a number of manuscripts and plates. In 1805 he published Histoire naturelle et mythologique de l'ibis (Natural and mythological history of the ibis).
By 1817, Savigny's eyesight had deteriorated, and he had to stop working for a number of years. Between 1816 and 1820 he published the important Mémoires sur les animaux sans vertèbres (Memoires on the animals without vertebrae). After returning to work in 1822, his eyesight continued to worsen, and by 1824 he became more-or-less blind, with terrible "optical hallucinations." Victor Audouin offered to complete Savigny's work but Savigny refused to part with the original artwork. Savigny was elected member of the Academy of Science on July 30, 1821.
