	James Anderson has pioneered the development and application of instruments to determine the chemical abundance of chemical radicals in the stratosphere. He established from measurement and theory the abundance of ClO in the stratosphere and then OH, NO, and BrO. This showed unambiguously that Cl from chloroflourocarbons was the cause of the ozone depletion in the Antarctic and that ClO and BrO from industrial sources was the cause of the ozone depletion. They are the basis for quantitatively testing models of the atmosphere. These results are from the very difficult and sophisticated measurements made by him with instrumented stratospheric ballon flights. Dr. Anderson has established a world center of research with brilliant young scientists who are participating in carrying their field forward. Having been Philip S. Weld Professor of Atmospheric Chemistry at Harvard Univeristy since 1978, Dr. Anderson has also served on the faculties of the University of Pittsburgh and the University of Michigan. He is a member of the National Academy of Sciences (1992); the American Academy of Arts & Sciences (1985); and the American Association for the Advancement of Science (1986). He holds a Ph.D. from the University of Colorado (1970).

2	Name:	Dr. Ahmed H. Zewail

	Ahmed Zewail was the 1999 Nobel Laureate in Chemistry. He was the Linus Pauling Chair Professor of Chemistry and Professor of Physics and the Director of the Physical Biology Center at the California Institute of Technology until his death on August 2, 2016, at the age of 70. Dr. Zewail was educated in Egypt and received his B.S. and M.S. from Alexandria University and his Ph.D. from the University of Pennsylvania. His research interests were directed towards the development of new methodology for understanding the dynamical behavior of life molecules in space and time. Dr. Zewail was the recipient of honors and awards from around the world, including Egyptian postage stamps issued to honor his contributions to science and humanity. He held some 30 honorary degrees in science, medicine, philosophy, law, arts and humane letters. A member of numerous international academies, Ahmed Zewail was elected to the American Philosophical Society in 1998.
