Jesuit Reductions
The presence of Hungarians in Argentina dates back to the 18th century, when a number of Hungarian Jesuit priests came to North Argentina and Paraguay and settled in Jesuit Reductions. After the fall of the Hungarian Revolution of 1848 a number of Hungarian officers fled to Argentina. Among them were János Czetz, founder of the Colegio Militar de la Nación (the Argentine National Military Academy) and Alexander Asboth, who served as United States Ambassador to Argentina. Another well-known Hungarian emigrant to Argentina is László Bíró, who perfected and patented his invention, the ballpoint pen – also known as biro – after his emigration to Argentina.
