Who then is Javier Prado?
According to the Spanish Wikipedia Javier Prado is a historian, philosopher and lawyer. He served as the principal of the San Marcos University from 1915 to 1920 and he held various political offices, among others as a senator and an ambassador to Argentina. He may have owed his political career to the fact that he was the son of an ex-President (Mariano Ignacio Prado). His brother Manuel Prado y Ugarteche would later go on to become president of Peru as well. At that time, Javier Prado already passed away. He died in 1921 under mysterious circumstances (according to Wikipedia) when he was only 49 years old.
