Could he be this guy here:

M. Colson, naturaliste, chef de bataillon au 75me de ligne
I have no clue if Achille Colsons bataillon (or any he was associated with) was in Algeria in 1850 but a naturaliste would somehow fit.
And Laurent wrote: I ran into this one earlier as well. But a note about him at : https://books.google.be/books?id=BFFFAAAAYAAJ&pg=PA211 says nothing about Algeria and indicates that he died in 1856, which doesn't seem to be a good match for the guy we're after...
A. Colsoni is named for two French soldiers named Colson . One was a naturalist in the 67th and 75th regiments of the line in the late 1840’s. He got a grave malady while a naturalist (Im guessing Malaria) not necessarily in Algeria. Achille Louise-Aug. Colson 1815 to 1856) His first cousin in the time range for the bird was stationed in province Constantine in Algeria. Their common grandfather was a doctor. I assume this is where they learned anatomy, botany and zoology. The other cousin became a general and was killed in the Franco-Prussian war in 1870. I think he killed the bird sent the three to his cousin who could not identify them and on and on. I think there use to be a middle form of Imperial Eagle which was extirpated by climate change

Mark, remember (as far as I can tell) we're looking for a (one certain) Colson who died:
As far as Bailly tells us, there is no doubt about this.
One possible caveat being that the birds had been received, and the name coined, by Fairmaire, not by Bailly -- it's not unconceivable that Bailly misunderstood a part of the story.

I remembered something along those lines too, so I tried to trace it back.
It is indeed believed that a population of imperial eagles, which is now extinct, existed in Algeria until (at least) the mid-19th C. But the most current interpretation seems to be that these birds were heliaca, rather than adalberti.

Following the clue given in BBOC 109 (2), 1989; "Malherbe (1855)" takes us to; Faune Ornithologique de L'Algerie, in Bulletin de la Societe d'Histiore naturelle du Département de la Moselle. No. 7, 1855 (here), all in French.

Any help?

PS. Regarding its identity that is. No Monsieur Colson mentioned. ;)
 
No, there is no description of the bird(s), so they cannot be identified from this.
This is also earlier than the description of Aquila adalberti Brehm 1861, thus the author cannot have been aware of the differences, and his identification cannot be trusted.
 
Thanks Laurent I believe Bailly got the story wrong. We need DNA . Muséum d’Histoire Naturelle de Grenoble has the Bailly bird skin collection.
