    Dr.Ahmed Zewail was born and raised in Egypt on February 26,1946,he received both his bachelor's(B.S. with honors in 1967) and master's degrees(M.S. in 1969) from Alexandria University. He earned his doctorate(PHD. in 1974) from the University of Pennsylvania and joined the Caltech faculty in 1976 after two years as an IBM Fellow at the University of California at Berkeley. He has a family of four children and his wife Dema Zewail, a physician in public health (UCLA)
    Dr.Zewail is a member of the National Academy of Sciences (USA); American Academy of Arts and Sciences; Third World Academy of Science (Italy); and the European Academy of Arts, Sciences and Humanities (France); the Pontifical Academy of Sciences; and is a Fellow of the American Physical Society and Sigma Xi Society. He is a member of the Pontifical Academy of Sciences.
    He has received numerous international prizes and awards like the Benjamin Franklin Prize in 1998, the Robert A. Welch Award in 1997, the King Faisal Prize in 1989, the Wolf Prize in 1993, the Carl Zeiss Award in 1992, the Leonardo da Vinci Award of Excellence in 1995, the Bonner Chemiepreis Award, and the Medal of the Royal Netherlands Academy of Arts and Sciences.
    Also he received national prizes like the Harrison-Howe Award, the ACS Peter Debye Award in 1996, the E. Bright Wilson Award, and the Buck-Whitney Award. The American Physical Society has honored Dr. Zewail with the Earle K. Plyler Prize and the Herbert P. Broida Prize in 1995. He has also received the Chemical Sciences Award from the National Academy of Sciences. In 1995, the president of Egypt, H. Mubarak, honored Dr.Zewail with the Order of Merit, First Class.
    Dr.Ahmed H. Zewail has won the 1999 Nobel Prize in chemistry for his work in viewing and studying chemical reactions at the atomic level as they occur.

    Nobel Prize 1999 in Chemistry

    Dr. Ahmed H. Zewail has won the 1999 Nobel Prize in chemistry for his groundbreaking work in viewing and studying chemical reactions at the atomic level as they occur. The announcement was made today by the Royal Swedish Academy of Sciences.
    “The Royal Swedish Academy of Sciences citation: For his studies of the transition states of chemical reactions using femtosecond spectroscopy”.
    This year's laureate in Chemistry is being rewarded for his pioneering investigation of fundamental chemical reactions, using ultra-short laser flashes, on the time scale on which the reactions actually occur. Professor Zewail's contributions have brought about a revolution in chemistry and adjacent sciences, since this type of investigation allows us to understand and predict important reactions.
    The academy said Zewail's work in the late 1980s led to the birth of femtochemistry, the use of high-speed cameras to monitor chemical reactions at a scale of femtoseconds.
    We have reached the end of the road. No chemical reactions take place faster than this," the academy said
    "We can now see the movements of individual atoms as we imagine them. They are no longer invisible," the academy said.
    A U.S. and Egyptian citizen, Zewail has held the Linus Pauling chair of chemical physics at the California Institute of Technology in Pasadena since 1990.
    The prizes, worth $960,000, are presented on December 10, the anniversary of the death of Alfred Nobel, the Swedish industrialist and inventor of dynamite who established the prizes.
    Mubarak congratulates Zewail
    President Hosni Mubarak sent a cable of congratulations to the renowned Egyptian physicist Ahmad Zewail on winning the Nobel Prize for chemistry.
    President Mubarak voiced his pride that one of Egypt`s exemplary sons has been honoured by the international community and wished Zewail further success.
    Dr. Zewail was also given a warm public and official welcome at his home-town in the Delta, where his name was given to major institutions and public facilities, in recognition of his outstanding achievements and filial gratitude to his home-country.

    Biography of Dr.Ahmad Zewail


    ahmed Zewail was born in February 26, 1946, in Egypt where he grew up, Zewail received both his Bachelor of Science and his master's degrees from Alexandria University Alexandria.
    He began his professional career as an undergraduate trainee at Shell Corporation in Alexandria in 1966.
    After continued studies in the U.S.A. he graduated for Ph.D. in 1974 at the University of Pennsylvania.
    After the completion of his Ph.D., he went to the University of California, Berkeley, as an IBM research fellow. Zewail was appointed to the faculty at Caltech in 1976 at the age of 30 as an assistant professor of chemical physics.
    In 1982 he was tenured, as he became a full professor, and in 1990 was honored by the first Linus Pauling Chair at Caltech.
    At the age of 52, Zewail won the “Banjamin Franklin” prize after his latest scientific achievements known as the femto_second which is the smallest part of he second, he received the prize at a lavish ceremony attended by some 1,500 scientists, students, officials and figures, including former US Presidents Jimmy Carter and Gerald Ford.
    In 1999, Dr. Ahmed Zewail, a laser expert was nominated for the Nobel Prize for Chemistry and by that he is the first Egyptian to be nominated for this honourable prize.
    Dr. Zewail is the first originally Arab Muslim scientist to win such prize since Naguib Mahfouz, who won the literature prize in 1988, and late President Anwar Sadat, who shared the peace prize in 1978. But he is the first to take one of the prestigious awards for science. The Nobel carries an award of nearly one million dollars.
    Dr.Zewail currently holds both Egyptian and American Nationality.
    He has a family of four children and is married to Dema Zewail, a physician in public health (UCLA). His scientific family over the past 20 years consists of some 150 post-doctoral research fellows, graduate students and visiting associates. He lives in San Marino, California.



    Ahmed Zewail currently is the Linus Pauling Chair Professor of Chemistry and Professor of Physics at the California Institute of Technology, and Director of the NSF Laboratory for Molecular Sciences (LMS).
    Zewail's current research is devoted to developments of ultrafast lasers and electrons for studies of dynamics in chemistry and biology. In the field of femtochemistry, developed by the Caltech group, the focus is on the fundamental, femtosecond (10-15
    second) processes in chemistry and in related fields of physics and biology.

    Awards and Medals


    A sparkling star in the world of science, Dr. Ahmed Zewail, the Egyptian-born, American scientist has been recently the focus of both official and popular celebrations in his home country.
    At the age of 44, The California Institute of Technology has selected chemist Ahmed Zewail to be the school's first Linus Pauling Professor of Chemical Physics. The recently established professorship honors the career and achievements of the two-time Nobel laureate.
    Zewail said it is a "special honor" to be named the first Pauling Professor. "I feel Pauling is the greatest chemist of the 20th century," Zewail says. "He has had a tremendous impact on my work and [on that] of every chemist in the world."
    In 1995 he received the Order of Merit, first class, from President Mubarak in appreciation of the vital role he played to enrich science all over the world,
    and in 1998 a Postage Stamp, with Portrait, was issued by Egypt, he also holds honorary degrees from the American University (Cairo).
    Dr. Zewail, 52,was also awarded the 198-year old "Benjamin Franklin" Prize for the contributions he made in serving the realm of science.
    He won this international recognition after his latest discovery known as the Femto Second, which is the smallest part of the second. Philadelphia was the venue of the great celebration that was held on April 30 this year, as Egyptians all over the world fixed their eyes on the Philadelphia-based headquarters of Benjamin Franklin Foundation, where a key Egyptian scientist received the United States' most prestigious scientific award.
    Zewail is a member of the National Academy of Sciences and the Third World Academy of Sciences, He is also a member of the American Academy of Arts and Sciences, and the European Academy of Arts, Sciences and Humanities.
    his honors include the Alfred P. Sloan Foundation Fellowship; the Camille and Henry Dreyfus Teacher-Scholar Award; the Alexander von Humboldt Award for Senior United States Scientists; the American Chemical Society's Buck-Whitney Medal in 1985; the Harrison Howe Award; and the King Faisal International Prize.
    Over his long career, Zoweil managed to harvest an array of awards and medals, including the Welch Award in 1997, The Leonardo DaVinci Award of Excellence in 1995, the Wolf Prize in 1992, the Herbert P.
