He wrote Mémoire sur la famille des Carabiques, 6 volumes commencing 1848.
The subsequent roots have been traced to Antoine de Chaudoire from Poland whose son worked in the court of Stanislas-Auguste Poniatowski until his abdication in 1795, after which he moved to Bavaria where he received the hereditary title of Baron from Maximilien Joseph II in 1814.
Unfortunately for him, Eschscholtz died a few weeks before he joined the university, and Chaudoir began to work on his collections at the museum.
He was encouraged by Count Gustave de Mannerheim and in 1834 he travelled around Germany and met Louis Chevrolat in Hamburg.
He moved to Kyiv and then joined the Societe Imperiale des Naturlistes de Moscou in 1837.
Chaudoir died from a stroke on 6 May 1881 and was buried next to his daughter in their family vault at Amelie-Bains-Palalda.
