Ahmed Zewail 

Ahmed Zewail is an Egyptian-American chemist who lived in Los Angeles. His wife, Dima Al-Faham, is the daughter of Shaker Al-Faham. He has four sons. Zewail is also known as the Vimto chemist because of his invention of a microscope that shows lasers at a time of femtosecondity. , And Zewail died in the year of two thousand and sixteen after a conflict with cancer and was seventy years old. The birth and education of Ahmed Zewail Born on February 26, 1964, in the city of Damanhour in Egypt, Ahmed Zewail was born in Damanhour, Egypt. When he was four years old, he moved with his family to the city of Disuq. Zewail graduated from the Faculty of Science at the University of Alexandria. He graduated with honors in the Bachelor of Science in Chemistry, in the year one thousand nine hundred and sixty-seven. He then worked as a lecturer in the faculty and received a master's degree. His thesis was on research in light science. Zewail traveled to the United States in a scholarship, received his Ph.D. from the University of Pennsylvania in Laser Sciences, then worked as a researcher at the University of California, and in 1991 he was awarded US citizenship. To become a major professor of chemistry, and the post is one of the highest scientific positions in America. Ahmed Zewail's inventions Dr. Ahmed Zewail invented a high-speed laser-imaging system that has the ability to track the movement of molecules at the time of their creation. When combined, the time unit that takes the picture is called femtocene, part of a million billionths of a second. Dr. Zewail has conducted more than 300 scientific research papers and published his research papers in all the world's leading scientific journals, such as Cites Magazine and Nature magazine. Dr. Zewail was listed in the United States Honorary List, a list of the most important figures that contributed to the development of America. He was ranked ninth out of twenty-nine eminent persons by being named the most important laser scientist in America, including Einstein and Graham Bell. Ahmed Zewail won the Nobel Prize Dr. Ahmed Zewail received the Nobel Prize in Chemistry in 1991, as a result of his invention of a femtosecond spectroscopy camera, in addition to studying chemical reactions through it. Thus, he became the first Arab scientist to win the Nobel Prize in Chemistry. His invention led to a revolution in the world of chemistry and related sciences. 

Ahmed Zewail, the Linus Pauling Professor of Chemistry, professor of physics, and director of the Physical Biology Center for Ultrafast Science and Technology at Caltech, passed away on Tuesday, August 2, 2016. He was 70 years old. 

Zewail was the sole recipient of the 1999 Nobel Prize in Chemistry for his pioneering developments in femtoscience, making possible observations of atoms in motion on the femtosecond (10-15 seconds) time scale. These developments led to the establishment of the discipline of femtochemistry. More recently, he and his group developed "4D" electron microscopy for the direct visualization in the four dimensions of space and time of materials and biological behaviors. 

For his contributions to science and for his public service, Zewail received honors from around the globe. Fifty honorary degrees in the sciences, arts, philosophy, law, medicine, and humane letters were conferred on him, including those from Oxford University, Cambridge University, Peking University, École Normale Supérieure, Yale University, University of Pennsylvania, and Alexandria University. 

Zewail was decorated with the Order of the Grand Collar of the Nile, Egypt's highest state honor, and was named to the Order of Légion d'Honneur by the President of France, among other state honors. He was an elected member of academies and learned societies including the National Academy of Sciences, the Royal Society of London, the American Philosophical Society, the French Academy, the Russian Academy, the Chinese Academy, and the Swedish Academy. Postage stamps have been issued in commemoration of his contributions to science and humanity. 

"Ahmed was the quintessential scholar and global citizen," says Caltech president Thomas F. Rosenbaum, the Sonja and William Davidow Presidential Chair and professor of physics. "He spent a lifetime developing instruments that interrogate nature in fundamentally new ways, and defining new directions that cut across the physical and biological sciences. Ahmed's fervor for discovery never abated and he serves as an inspiration to colleagues and generations of students. The Caltech community deeply mourns his loss." 

"Ahmed Zewail was a great man for chemistry, for science, and for society. All of us at Caltech grieve his loss," says Jacqueline K. Barton, Arthur and Marian Hanisch Memorial Professor of Chemistry and Norman Davidson Leadership Chair of the Division of Chemistry and Chemical Engineering. 

Among the more than 100 international prizes and awards, he was the recipient of the Albert Einstein World Award, the Benjamin Franklin Medal, the Leonardo da Vinci Award, the Robert A. Welch Award, the Wolf Prize, the King Faisal Prize, the Othmer Gold Medal, and the Priestley Gold Medal. In his name, international prizes have been established in Amsterdam, Cairo, Detroit, Trieste, and Washington, D.C.; in Cairo, the AZ Foundation provides support for the dissemination of knowledge and for merit awards in arts and sciences. 

Following the 2011 Egyptian revolution, the government established Zewail City of Science and Technology as the national project for scientific renaissance, and Zewail became its first chair of the Board of Trustees.
