Maryam Jameelah (May 23, 1934 - October 31, 2012) was an American-Pakistani author of over thirty books on Islamic culture and history and a prominent female voice for conservative and fundamentalist Islam, known for her disparaging writings about the West. Born Margret Marcus in New York City to a non-observant Jewish family, she explored Judaism and other faiths during her teens before converting to Islam in 1961 and emigrating to Pakistan. She was married to and had five children with Muhammad Yusuf Khan, a leader in the Jamaat-e-Islami political party, and resided in the city of Lahore.
Jameelah was born Margret Marcus in New Rochelle, New York, to parents of German Jewish descent, and spent her early years in Westchester. As a child, Marcus was psychologically and socially ill at ease with her surroundings, and her mother described her as bright, exceptionally bright, but also "very nervous, sensitive, high-strung, and demanding". Even while in school she was attracted to Asian and particularly Arab culture and history, and counter to the support for Israel among people around her, she generally sympathised with the plight of Arabs and Palestinians. Another source describes her interests as zigzagging from Holocaust photographs, to "Palestinian suffering, then a Zionist youth group and, ultimately, fundamentalist Islam."
She entered the University of Rochester after high-school, but had to withdraw before classes began because of psychiatric problems. In Spring, 1953, she entered New York University. There she explored Reform Judaism, Orthodox Judaism, Ethical Culture and the Bahá'í Faith, but found them unsatisfactory, especially in their support for Zionism. In the summer of 1953, she suffered another nervous breakdown and fell into despair and exhaustion. It was during this period that she returned to her study of Islam and read the Quran. She was also inspired by Muhammad Asad's The Road to Mecca, which recounted his journey and eventual conversion from Judaism to Islam. At NYU she took a course on Judaism's influence on Islam which was taught by Rabbi and scholar Abraham Katsch, which ironically strengthened her attraction to Islam. However Marcus's health grew worse and she dropped out of the university in 1956 before graduation; from 1957 to 59 she was hospitalized for schizophrenia.
