Ignacy Domeyko

After a youth passed in partitioned Poland, Domeyko participated in the Polish–Russian War 1830–31. Upon Russian victory, he was exiled, spending part of his life in France (where he had gone with a fellow Philomath, Polish poet Adam Mickiewicz) before eventually settling in Chile, whose citizen he became.
He lived some 50 years in Chile and made major contributions to the study of that country's geography, geology and mineralogy. His observations on the circumstances of poverty-stricken miners and of their wealthy exploiters had a profound influence on those who would go on to shape Chile's labor movement.
Domeyko is seen as having had close ties to several countries and thus in 2002, when UNESCO organized a series of commemorations of the 200th anniversary of his birth, he was referred to as "a citizen of the world". Provided by Wikipedia
