Pando was born Madrid. After studying agriculture and industry, he took part in the Dos de Mayo Uprising during the War of Spanish Independence. Later he had to flee, together with his family, to Cádiz. After the accession to the throne of Ferdinand VII of Spain, the latter's uncle, Infante Antonio Pascual of Spain asked Pando advice for the writing of the Memorial of Miraflores, which aimed to solve the situation after the end of the French domination in Spain.
