Archduke Carl Ludwig of Austria (1918–2007)

During the Second World War, Karl Ludwig and his brother Felix volunteered to serve in the 101st Infantry Battalion of the United States Army, known as the "Free Austria Battalion". However, the battalion was disbanded when a number of exiled Jewish volunteers who made up the majority of the force ultimately declined to confirm their enlistment.[3]

He was buried beside his mother in the Kapuziner Crypt in Vienna.

He was married in Belœil on 17 January 1950 to Princess Yolande of Ligne (born 6 May 1923). They had four children.
