American Jesuits replaced their Spanish brethren in 1921. In 1932, the original campus at Intramuros in Manila was destroyed by fire and the Ateneo moved to the San Jose Major Seminary grounds in Padre Faura, Ermita. The Intramuros campus was rebuilt in 1939. The Ateneo campuses were destroyed again in World War II. The Ateneo reopened temporarily in Plaza Guipit in Sampaloc, Manila. The Padre Faura campus reopened in 1946 with Quonset huts serving as buildings among the campus ruins. In 1952, William Masterson moved most of the Ateneo units to its present Loyola Heights campus. The Padre Faura campus continued to house the professional schools until 1976. Francisco Araneta was appointed as the Ateneo de Manila's first Filipino rector in 1958. In 1959, its centennial year, Ateneo became a university.
