John S. Rigden, Ph.D., adjunct professor of physics in Arts & Sciences, reviews the recently hung Eads Hall display recognizing physicist Arthur Holly Compton, Ph.D., the University’s first faculty member to receive a Nobel Prize (1927), and his groundbreaking research. The American Physical Society (APS) named WUSTL — where Compton did his Nobel Prize-winning research on X-rays — to its Register of Historic Sites. An APS plaque now hangs just inside Eads Hall’s main entrance alongside a University plaque that marks the building in which Compton discovered the X-ray scattering effect; a photo and biography of Compton; and his early X-ray research that he started in 1920 on the RMS Aquitania while sailing from England to the United States to begin his WUSTL appointment as the Wayman Crow Professor of Physics and chair of the physics department.
