Archduke Ludwig Viktor of Austria

Archduke Ludwig Viktor Joseph Anton of Austria was the youngest child of Archduke Franz Karl of Austria and Princess Sophie of Bavaria, and the youngest brother of Emperor Franz Joseph I.

He is well known for his art collection and patronage as well as philanthropy.
