Ludwig von Wallmoden-Gimborn, Austrian general (d. 1862)
Ludwig Georg Thedel Graf von Wallmoden (6 February 1769 – 22 March 1862) was an Austrian "General of the Cavalry", best known for his training of light infantry and the refinement of the Tirailleur system. As a grandson of George II of Great Britain and first cousin of George III, he is perhaps the only individual from that generation to have been photographed, within the broader British royal family.
