José Eusebio de Llano Zapata

José Eusebio de Llano Zapata (1721–1780) was a Peruvian scholar, writer and scientist. He was born in Lima, Peru in 1721 and died in Cadiz, Spain in 1780. He was the son of Diego de Llano Zapata and Rosa Valenzuela.

José Eusebio de Llano Zapata studied at the Franciscan College of Buenaventura de Guadalupe and was a private student of Jesuit scholars like José Ignacio de Vargas, Alonso de la Cueva, through whom he must have had access to the best library in America at that time, the Library of the Maximum College of San Pablo de Lima.

Between 1751 and 1755 he traveled to Chile, Buenos Aires and Rio de Janeiro. In an effort to publish his historical, physical, apologetic memoirs of South America he traveled to Spain in 1755 to get authorization but his efforts to achieve this were fruitless. During his residence in Spain he published a preliminary to the Memoirs, in addition to compiling an epistolary with personalities of the time publishing them in two volumes.
