Biography

He is the son of the general Jean François Aimé Dejean (1749-1824). Soldier, it is useful in the Napoleonean Armée S. It becomes Brigadier general at 30 years in 1810 Major general and in 1813. He is as of 1813 Aide-de-camp of Napoleon {{Ier}}, takes share with the battles of Ligny and of Waterloo, by the Bourbon S of 1815 with 1819 is exiled.

Large specialist in the Coleopter S and more particularly in the Carabidae, it assembles the largest collection deprived ever carried out. He receives specimens of all the corners of planet and its final catalog counts: 22000 S identified. It employs Jean-Baptiste Alphonse Dechauffour de Boisduval (1799-1879) like conservative of its collection. An anecdote indicated the enthusiasm of Dejean for these animals: at the time of the battle of Alcanizas in Spain, Dejean was about to give the order of the attack when he noticed a coleopter posed on a flower. It went down then from horse, collected it and pricked it at the bottom of its hat. It went up on its horse, and gained the battle after a hard combat where it made a great number of prisoners. Its hat had been shredded by enemy shootings, but it had satisfaction to find intact its insect.

Its catalog raised many polemics because it did not comply with the rule linnéenne anteriority: I had a rule always to preserve the name most generally used, and not necessarily more ancien.

He is the author of many publications which cover very many species. However, the initial plan of sound Species Général of the Coleopters of the Collection of Mr. the Count Dejean was even more ambitious because it wished to cover the totality of the known coleopters whereas it had to be limited to describe those of his collection. The five first of six volumes are with its hand.
