author
1750–1820
An 18th-century French-born writer, mathematician, and royal officer, he left behind vivid works on travel, geography, and routes across South America. His books open a window onto the late colonial Río de la Plata and the practical world of exploration, mapping, and communication.

by José Sourryère de Souillac
Born in 1750 and died in 1820, José Sourryère de Souillac is listed by major library records as a French-linked author who wrote in Spanish. Modern catalogues and digital libraries preserve works attributed to him, including Itinerario de Buenos Aires a Córdoba and Descripción geográfica de un nuevo camino de la gran cordillera, which connect his name with travel writing, geography, and overland routes in southern South America.
Recent scholarly work describes him more specifically as a mathematics teacher and a servant of the Spanish monarchy whose career unfolded in part in the Viceroyalty of the Río de la Plata. That background helps explain the practical tone of his surviving writings: they are not just literary, but useful records shaped by administration, measurement, movement, and the realities of long-distance communication.
For today's listeners, his appeal lies in that mix of observation and function. His books capture a world where roads, frontiers, and mountains were not abstractions, but urgent problems to be described clearly and crossed as safely as possible.
