Cadet bios.
Teadora Brnardic has written an article called “The Everyday Life of Cadets at the Wiener Neustadt Military Academy as Represented on the Paintings by Bernhard Albrecht (1785-1793)", which is to be published in the on-line Italian journal History of Education & Children's Literature. Should be in the next edition, which has presumably been delayed.
