AKA فاطمة المرنيسي
Mernissi was born into a middle-class family. She received her primary education in a school established by the nationalist movement, and secondary level education in an all-girls school funded by the French protectorate. In 1957, she studied political science at the Sorbonne and at Brandeis University, where she earned her doctorate. She returned to work at the Mohammed V University and taught at the Faculté des Lettres between 1974 and 1981 on subjects such as methodology, family sociology and psycho-sociology. She has become noted internationally mainly as an Islamic feminist.
As an Islamic feminist, Mernissi was largely concerned with Islam and women's roles in it, analyzing the historical development of Islamic thought and its modern manifestation. Through a detailed investigation of the nature of the succession to Muhammad, she cast doubt on the validity of some of the hadith (sayings and traditions attributed to him), and therefore the subordination of women that she saw in Islam, but not necessarily in the Qur'an.
As a sociologist, Mernissi did fieldwork mainly in Morocco. On several occasions in the late 1970s and early 1980s she conducted interviews in order to map prevailing attitudes to women and work. She did sociological research for UNESCO and ILO as well as for the Moroccan authorities. In the late 1970s and in the 1980s Mernissi contributed articles to periodicals and other publications on women in Morocco and women and Islam from a contemporary as well as from a historical perspective.
In 2003, Mernissi was awarded the Prince of Asturias Award along with Susan Sontag.
Mernissi was a lecturer at the Mohammed V University of Rabat and a research scholar at the University Institute for Scientific Research, in the same city.
