Voltigeur

That uniform belongs to the Chasseurs d'Afrique, and appears to be the post 1860 Pelisse for officers. There were NO Hussards in the Imperial Guard Cavalry. The kepi looks like a cheapo nasty very very bad repro

I have a copy of the same photograph but in black and white and a further copy of it - not mine! - also appears in Delperier, Malvaux, Joineau, "La Garde Imperiale du Napoleon III" on p. 57. In the past lots of copies of Cartes de Visites were made and given out as business cards the same goes with Studio Portrait like this one, by the prestigious Maison Disderi in Paris, which were given to friends and family. HIs full name appears to be Jules Armand d'Auvergne. I can only find him in the Annuaire de l'Armee for 1861 and 1866, sadly. I will have an other hunt!

This officer is Capitaine Jules d'Auvergne, 1ere Regiment des Voltigeurs de la Garde. He was promoted to the rank of Capitain in 1848; joined the Imperial Guard in 1854 in the 1ere Voltigeurs; passed into the 6e Regiment de Ligne in 1861; promoted Chef de Bataillon 1862 and retired in 1866. This photograph was taken in 1869. He is a Captain because he has a fringed epaulette on each shoulder: lieutenants had a fringed epaulette on the left shoulder and fringless on the right and sous-lieutenants the opposite. His shako has the disctinctive joinquille over red pompon a flamme; the red over joinquille pompon was adopted on 17th OCtober 1854 replacing the previous entirely joinquille one. The shako has lace in V chevrons on each side, a feature unique to the Imperial Guard and it also has a rounded peak, again unique to the Guard as the Line had square peaks. He can be closely dated to between 1857 and 1860 as that was when the Voltigeurs adopted the red trousers of the line, replacing the previous dark blue onesand before the Voltigeurs adopted a new uniform in 1860.
