Francisco Pascasio Moreno

Francisco Pascasio Moreno (May 31, 1852 – November 22, 1919) was a prominent explorer and academic in Argentina, where he is usually referred to as Perito Moreno (perito means "specialist, expert"). Perito Moreno has been credited as one of the most influential figures in the Argentine incorporation of large parts of Patagonia and its subsequent development.

Life and work

Moreno was born to Francisco and Juana Thwaites Moreno in Buenos Aires. Raised in a traditional patrician family, he studied in local parochial schools. He shared his spare time with his father searching for artifacts and fossils and, at age 14, created a homemade museum of his extensive collections.

Following graduation in 1872, he participated in the founding of the Argentine Scientific Society. He embarked on the first of the series of scientific expeditions that made him well known: a survey of Río Negro Territory, largely uncharted country. In January 1876, he reached Lake Nahuel-Huapi in the southern Andes, and on February 15, 1877, he discovered and named Lake Argentino. He also explored numerous rivers in Patagonia. On March 2, he discovered and named Mount Fitz Roy, after the commander of the expedition of HMS Beagle in the 1830s. The native people also called it Chalten.

In 1880, Moreno went to France, where he spoke at a meeting of the Anthropology Society of Paris, discussing two prehistoric skulls he had unearthed in Río Negro territory. He believed one was from the Quaternary period, and the other had ritual deformation in a manner similar to the skulls of the Aymara people of the Andes and Altiplano.
