The Princess stipulated that the organization's president should always be a princess of the family, and that all committee members should be women.[2] The society was codirected by two aristocratic women, the Muslim Hidaya Afifi Barakat (1899-1969) and the Christian Mary Khalil (1889-1979). It survived the 1952 Revolution, when many independent organizations were closed down. The society's hospitals were eventually nationalized in 1964, by which time they had treated around 13 million women.[3]
