[3] Approximately 44,000 Swiss emigrated to Argentina until 1940, who settled mainly in the provinces of Córdoba and Santa Fe and, to a lesser extent, in Buenos Aires.

Félix Fernando Bernasconi was a Swiss Argentine shoe manufacturer to whom Francisco Moreno sold a property on the southside of Buenos Aires.

In addition, Emilio Frey, son of a Swiss immigrant and educated in Switzerland, became an important partner of Moreno as topographer of the Comisión de limites Argentina-Chile from 1896 to 1902 to work out a new treaty for the border between the two countries.

Another colony was Villa Urquiza, made up of Swiss families that had the province of Corrientes as their original destination but ended up settling in Entre Ríos.

In Río Negro there is a town called Colonia Suiza where the Swiss settlement was formed in the late nineteenth century.

One of the major Swiss pioneers was Guillermo Lehmann (born in Winterthur, Canton of Zürich), who founded several villages and towns between 1870 and 1880, with Rafaela, Santa Fe being one of the most important settlements.
