Sameera Moussa was born in El Gharbia, Egypt in 1917. She was raised by her single father, a political activist, after her mother died of cancer, which set her life trajectory to study unique ways to treat cancer. Although her GPA from secondary school was high enough to study engineering (the top ranked course) she chose to study science at Cairo University. In 1939, after finishing undergraduate research on the effects of Xray on different materials, Sameera Moussa graduate from Cairo University with a BSc in radiology. After obtaining a doctorate in atomic radiation, she would go on to become the first woman to work at Cairo University. One of her most notable contributions to the field of nuclear physics is the International Atomic Energy For Peace Conference. At the conference, she advocated for affirdable and accessible nuclear treatments for disease, while also creating a committee whose goal was to protect against potential nuclear hazards. Because of her incredible contributions to the field and her knowledge, she was invited to the US on a Fulbright Atomic fellowship. During her time in the US, she traveled to California University where she had the chance to visit top secret atomic facilities. These visits would later spark outcry was she was the first noncitizen ever to visit these facilities. At the end of her fellowship, she received an offer of a green card to work in the US but rejected it, wishing to return to Egypt. In 1952, just days before she was meant to return to Egypt, she died in a car accident off the California coast, in what some allege to be an assassination by Israel’s Mossad. She was 35 years old.
