In the May 22 issue of Frontline I had described the work of Dorothy Hamre, at the University of Chicago, on the discovery of coronaviruses (unnamed at that time) in the mid 1960s. In my search for the discoverer of coronavirus strain 229E, the first human pathogen identified for this new class of viruses, I ended on the hopeful note that we would soon obtain an authentic photograph of this largely unknown but pioneering scientist. That goal has now been reached, with the discovery of material deposited by her husband, Alexander Brownlee, at the Cline Library Archives, North Arizona State University at Flagstaff.
