Biography
Pedro Peralta y Barnuevo was born on November 26, 1663, in Lima, Peru. His father, Francisco Peralta Barnuevo, was a Spaniard serving as a royal accountant of the Court of Audit, and his mother, Magdalena E. Rocha Benavides, was from Lima. His brother José de Peralta Barnuevo later became the Bishop of Buenos Aires. Pedro completed his education at the University of San Marcos in Lima, where he studied Roman and canonical art and law, earning a doctorate between 1680 and 1686. In 1687, he became a lawyer before the Royal Court. After his father's death, he took over the royal accountant role and also received income from his wife's estates.
Peralta was remarkably talented, knowing at least seven languages, including Latin, Greek, French, Portuguese, Italian, English, and Quechua, the indigenous Andean language. This allowed him to access a wide range of scientific and literary works. His personal library was diverse, with books on grammar, military science, astronomy, metallurgy, and more. He wrote about poetry, history, mathematics, and cosmography, earning a reputation as one of the leading thinkers in colonial Spanish America.
In 1715 and 1716, Peralta was the rector of the University of San Marcos, during a challenging time. His leadership showed his administrative and academic strengths. He was chosen as a member of the Académie des sciences of Paris, a sign of his high regard among European scholars during the Enlightenment.
A major event in his later career was his work with the Franco-Spanish Geodesic Mission starting in 1735. Led by French naturalist and geographer Charles Marie de la Condamine, the mission aimed to measure a meridian arc near the equator to determine the Earth's shape. Spanish officers Antonio de Ulloa and Jorge Juan were also key figures. Peralta's involvement in this mission helped him become a member of the Académie des sciences and showed his participation in a significant 18th-century scientific project.
Pedro Peralta y Barnuevo died on April 30, 1743, in Lima, where he had lived most of his life, while maintaining connections across Europe and the Atlantic.
Before Fame
Pedro Peralta y Barnuevo grew up in Lima during the second half of the 1600s, when the Viceroyalty of Peru was the main administrative and cultural hub of Spanish South America. Born into a family with ties to the colonial government, he had access to the University of San Marcos, one of the oldest universities in the Americas, established in 1551. His early studies in law and canon law gave him a strong intellectual foundation that he continued to build on throughout his life.
The Lima of Peralta's youth was a city where European learning, especially Spanish scholasticism, existed alongside the practical needs of managing a large territory. Peralta stood out not only in his legal studies but also in his self-driven pursuit of languages and sciences, which went beyond the standard curriculum. By the time he completed his doctorate and joined the bar in the mid-1680s, he had already formed the study and inquiry habits that would shape his career.
