It is with sadness that we report the death of femtochemistry pioneer and Nobel laureate Ahmed Zewail at the age of 70. Egyptian-born Zewail was the Linus Pauling Professor of Chemistry, professor of physics, and director of the Physical Biology Center for Ultrafast Science and Technology at Caltech. He was the sole recipient of the 1999 Nobel Prize in Chemistry for his work that made possible observations of atoms in motion on the femtosecond (10^15 second) timescale. "Ahmed was the quintessential scholar and global citizen," says Caltech president Thomas F. Rosenbaum. "He spent a lifetime developing instruments that interrogate nature in fundamentally new ways."
