Ahmed Hassanein Hashad, Professor of Geochemistry in the Nuclear energy Authoritydied on 14/12/2010. As he had generally been in good health, his death, which resulted from an unusual combination of circumstances, was a devastating blow to his family, friends and colleagues.

Prof. Hashad was born on July 19, 1938 in Cairo, and he attended several schools in Shubra area. In 1952 he entered the Department of Geology at Cairo University, obtaining a B.Sc. in 1957 in Chemistry- Geology with grade very good.

He began his practical career in July 1957 as a geologist in the phosphate company at Sebaya, Red Sea governorate. He moved to the Atomic Energy committee in October 1957 to begin his field work in Qatrani area in the Western Desert and Abu Zeneima area in Southern Sinai, 1958; and finally in Wadi El Gemal in the Eastern Desert 1959, where he succeeded in discovering new locations for radioactive mineralization.

He moved to U.S.A in December 1959 to begin his graduate studies at the University of Iota, Salt Lake City, Colorado. During his years at U.S.A he was a keen field geologist, but became increasingly interested in geochemistry, and made a detailed study of microchemical analyses of ores as part of his thesis work before receiving his Ph. D. degree in nuclear geochemistry in 1964.

In 1964 Hashad returned to Egypt to start his job as lecturer in the Nuclear Material Authority. In a highly productive period of two years he established Isotope geology laboratory.

The next move took Dr. Hashad to the Science Academy in Hungary in 1970 for one year, where he gave Lectures in Geochemistry in many Hungarian Universities and made many studies in the field of stable isotope geology.

One year later, he obtained the Assistant Professor degree in 1971 and appointed as Chairman of the Isotope geology unit and began supervising many M. Sc. and Ph. D. thesis in the field of geochronology and isotope geochemistry.

In 1974, he moved to King Abdel- Aziz University in Jeddah, Kingdom of Saudi Arabia for four years to develop a distinctive education system in the faculty of Science.

In 1978, he promoted to professor of geochemistry. His scientific experience gave him the opportunity for election as president of the Science research sector in the Nuclear Material Authority. During this period, he was elected as member of the Permanent Committee of the Nuclear Material Authority.

In 1983, Prof. Hashad moved back to Saudi Arabia where he spent about ten years till 1992. During this period he was involved in a giant project for studying the geochemistry and distribution of radioactive elements in northern Arabian Shield.

In 1992, he moved again to Cairo. One of his duties was the foundation of the "Knowledge Center" in the NMA. In 1994 he retired from active Administrationbut remained involved in national and international professional affairs.

In recognition of his contributions to geology, he was elected in 1970a member ofthe Syndicate of Scientific Professions.  In 1972, he was invited to be a founding member of the Arab Society for Nuclear sciences. In the same year, he was elected as member of its council. In 1993 he was elected asSecretary General, Syndicate of Scientific Professions.

Prof. Hashad has been decorated with many high awards: the Encouragement State Prize in Geology 1980, the Order of Science and Arts of the First Class in 1983, and Within the space of academic career he published more than forty scientific publications and two books. He has left a bibliography of more than 70 publications and supervised more than 30 M. Sc. and Ph. D. theses. His detailed study of the geologic structure, history, mineralogy, and geochemistry of the Egyptian radioactive minerals greatly clarified their nature. He described and investigated several new radioactive mineral locations; His study of radioactive minerals was extended into Saudi Arabia in the late 1970s.

Professor Hashad was a dedicated geochemist, and will be remembered as a kind teacher, friend and colleague. The loss to the Nuclear Material Authority and the scientific community of one who had so much yet to give is great, but nevertheless small compared to that suffered by his wife and two children.
