Pierre Naudin, from Pontaillier, France was born in 1819 and died in 1874. He also is known on many sites as Philibert Naudin but the reason is unclear to me.
His botanical story is unique as a military veterinarian who published a botanical book as he escaped the disaster at Sedan, in which Napoleon III as captured, but was imprisoned in Brussels. The Siege of Paris (1870-1871) followed the disaster at Sedan.
The book, Nouvelle iconographie fourragère, was a collaboration between himself and another veterinarian, Jean Gourdon, of Toulouse. Naudin’s military service started in 1842 and, in 1849, the two veterinarians collaborated on a work about the domestic animals of Algeria and were each awarded, by the Société nationale et centrale de médecine vétérinaire, a gold medal of 400 fr.
A sample of the plates are included below from the Nouvelle iconographie fourragère.
