Luis Piedrabuena

Luis Piedrabuena (Spanish pronunciation: [lwis pjeðɾaˈβwena]; 24 August 1833 - 10 August 1883) was an Argentine sailor whose actions in southern Argentina consolidated national sovereignty at a time when these lands were virtually uninhabited and were not protected by the state. His biographers consider him one of the most important heroes of Patagonia. Piedrabuena reached the naval rank of Naval Lieutenant Colonel, equivalent to Commander. Today he is commonly called Commander Piedrabuena.
