Archduke Albrecht, Duke of Teschen (d. 1895)
Archduke Albrecht Friedrich Rudolf Dominik of Austria, Duke of Teschen (3 August 1817 – 18 February 1895), was an Austrian Habsburg general. He was the grandson of Emperor Leopold II and one of the chief military advisors of Emperor Francis Joseph I. As Inspector General for 36 years, he was an old-fashioned bureaucrat who largely controlled the Austro-Hungarian Army and delayed modernization. He was honored with the rank of Field Marshal in the armies of Austria-Hungary (1863) and Germany (1893).

According to historians John Keegan and Andrew Wheatcroft:

He was a firm conservative in all matters, military and civil, and took to writing pamphlets lamenting the state of the Army’s morale as well as fighting a fierce rearguard action against all forms of innovation…. Much of the Austrian failure in the First World War can be traced back to his long period of power…. His power was that of the bureaucrat, not the fighting soldier, and his thirty years of command over the peacetime Habsburg Army made it a flabby instrument of war.
