Archduke Ludwig Salvator of Austria, in Italian Luigi Salvatore Maria Giuseppe Giovanni Battista Dominico Raineri Ferdinando Carlo Zenobio Antonino, in German Ludwig Salvator Maria Joseph Johann Baptist Dominicus Rainerius Ferdinand Carl Zenobius Antonin (Florence, 4 August 1847 - Schloss Brandeis, Brandýs nad Labem-Stará Boleslav, Bohemia, 12 October 1915), is known as a champion for Majorca's wildlife, in an era when the term "conservation" meant nothing. The Balearic Islands are commemorating the centenary of the death of Archduke Ludwig Salvator during 2015.
Ludwig Salvator settled on Majorca, buying up unimproved areas of land in order to preserve and enjoy them. His main residence of Son Marroig, near the village of Deià, is now a museum. Much of what was his property now belongs to the American actor Michael Douglas, notably the Moorish style palace 'S'Estaca' that Ludwig converted from a ruined old manor house.
About 1895, at Přerov nad Labem, Bohemia, he founded the first open-air museum in Central and Eastern Europe.
