Emilio Frey

He attended school in Switzerland from 1884 through 1892, staying first with his grandfather Rudolf Frey in Zurich, then continuing at the Technikum in Winterthur, today part of the Zürcher Hochschule für Angewandte Wissenschaften, where he studied cartography and got an engineering degree in 1892.

The Argentine minister for agriculture Ramos Mejia established another commission to study the hydrology of Northern Patagonia in 1910, which was led by professor Bailey Willis, a US geologist.

For the services Francisco Moreno provided as commissioner during the border disputes, the Argentine state granted him extensive land titles in Patagonia.

Moreno in turn gave back to Argentina a large area close to the Nahuel Huapi Lake under the condition, that this land should be protected as a national park.

He elaborated a park-regulation that prohibited the felling of wood in the state lands, the killing of wild animals, and it regulated slash-and-burn and defined emergency measures in case of forest fires.
