Jean-Baptiste Sabatier Blot (1801-1881), French.
 
Half plate, matted and framed, inscribed in ink on the mount, "Sabatier Palais Royal, 137." 7 x 8.5".
 
A fine portrait of a distinguished Frenchman striking a Napoleonic pose. Sabatier learned the daguerreotype process from Daguerre, and in 1844 took what is arguably the best, and most widely known, portrait of his teacher.
