Ahmed Hassan Zewail, (born February 26, 1946, Damanhur, Egypt), was an Egyptian
chemist, known as the “father of femtochemistry”. After receiving B.S. (1967) and M.S. (1969)
degrees from Alexandria University, and in 1990 he was selected as the school’s first Linus
Pauling Professor of Chemical Physics. In the late 1980s, Zewail was able to view the motion of
atoms and molecules by using a method based on new laser technology capable of producing
light flashes just tens of femtoseconds in duration. During the process, known as femtosecond
spectroscopy. In 1999, Zewail became the first Egyptian and the first Arab to receive a
science Nobel Prize when he was awarded the Nobel Prize in Chemistry. In 1999, he received
Egypt's highest state honor (the Grand Collar of the Nile). In October 2006, Zewail received
the Albert Einstein World Award of Science for "his pioneering development of the new field of
femtoscience and for his seminal contributions to the revolutionary discipline of physical biology,
creating new ways for better understanding the functional behavior of biological systems by
directly visualizing them in the 4D of space and time. In 2009, US President Barack Obama
appointed him to the White House presidential advisory board. Zewail was wrote about 600
scientific articles and 16 books, including "Voyage Through Time ... The Road to Noble, The Age
of Science" in 2005, and "Dialogue of Civilizations", in 2007.In August 2, 2016, He was died in
