At the age of 23, he went to Paris in 1946 to become a physicist. He remained there 15 years, studying physics under Frédéric Joliot-Curie, Marie Curie’s son-in-law, and ultimately translating parts of Einstein’s Theory of Relativity into his native Wolof. In the 1940s, the study of African history was dominated by (racist) Europeans who considered Africans ‘people without a past’. Diop recieved 5 PHd’s in Physics, African history, Egyptology, linguistics, anthropology,,and he also was well versed in Sociology and Economics, as he armed himself for the task of setting the historical record straight. Research In 1951, Diop submitted his first Ph.D. thesis at the University of Paris where he argued that ancient Egypt had in fact been a Black African culture. After 1960, Diop went back to Senegal and continued writing. A radiocarbon laboratory was established with the University of Dakar (which was later named Cheikh Anta Diop University of Dakar after his death), and Diop was made its head. He had said, “In practice it is possible to determine directly the skin color and, hence, the ethnic affiliations of the ancient Egyptians by microscopic analysis in the laboratory; I doubt if the sagacity of the researchers who have studied the question has overlooked the possibility.” One of his important works published in journals is the dosage test—a technique developed by Diop to determine the melanin content of the Egyptian mummies. This technique was later adopted by the U.S. forensic department to determine the racial identity of badly burnt accident victims. In 1974, Cheikh Anta Diop participated in a UNESCO symposium in Cairo, where he presented his theories to other specialists in Egyptology. He also wrote the chapter about the origins of the Egyptians in the UNESCO General History of Africa.
