Henry N. Chapman
Henry N. Chapman FRS (born 1967) is a British physicist and the founding director of the Center for Free-Electron Laser Science at the German Electron Synchrotron (DESY). He has made numerous contributions to the field of x-ray coherent diffraction imaging and is a pioneer of the diffraction before destruction technique that allows to analyze biological samples with intense, ultrafast x-ray light, such as Photosystem II, a key macromolecule in photosynthesis. He is married to the Slovenian physicist Saša Bajt. Education and career. Henry Chapman earned his Ph.D. from Melbourne University, in Australia. He then  joined Stony Brook University in the United States, working in the group of ‪Chris Jacobsen‬ on the National Synchrotron Light Source in the field of coherent diffraction imaging and X-ray crystallography. In 1996 he joined Lawrence Livermore National Laboratory where he worked on extreme ultraviolet lithography. In 2007, he moved to DESY to become the Founding Director of CFEL Coherent Imaging Group.
