A thread-like shape appears under the electron microscope in Atlanta
By October 1976, hemorrhagic fever had already killed hundreds across southern Sudan and northern Zaire, and nobody at the CDC could say for certain what was causing it. On October 13, in a lab in Atlanta, virologist Fred Murphy and his colleague Alyne Harrison aimed an electron microscope at a sample from the outbreak and got their answer. The image showed long, filamentous strands unlike anything in the usual hemorrhagic-fever catalog. The virus had a shape, and soon it had a name: Ebola.
The CDC's identification of Ebola helped establish the American public health system as a global reference point for naming and classifying emerging viruses. Murphy's image became the template electron microscopists worldwide still compare new filoviruses against. Atlanta's lab, not a hospital in Kinshasa or Khartoum, became the place the virus was first truly seen.
QWhat credentials did Fred Murphy hold before he ever looked at an Ebola sample?
Murphy arrived at the CDC with a veterinary science background rather than a strictly medical one. He earned a bachelor's degree and a Doctor of Veterinary Medicine from Cornell University, then added a PhD from the University of California, Davis. That combination of animal disease training and advanced virology research shaped his later leadership roles at the CDC, including stints as Director of the Division of Viral and Rickettsial Diseases and Director of the National Center for Infectious Diseases. After retiring from federal service in 2015, he carried that expertise into academia as professor emeritus of pathology at the University of Texas Medical Branch in Galveston. His path to the Ebola image ran through veterinary medicine, not a hospital ward.
QHow many peer-reviewed papers came out of Murphy's career after the Ebola discovery?
Murphy's publication record runs past 250 peer-reviewed journal articles, a body of work built across decades studying rabies and hemorrhagic fevers alongside his Ebola work. That output, plus his leadership positions inside the CDC's viral disease divisions, earned him numerous professional honors over his career. He also stayed active in professional organizations and committees well beyond the Atlanta lab bench. The 1976 micrograph remains his best-known image, but it is one entry among more than 250 papers.
QWhat institution did the CDC grow out of before it became a public health agency in Atlanta?
The CDC traces its origin to the Malaria Control in War Areas program, a World War II-era operation aimed at controlling mosquito-borne disease near military bases in the American South. That program was formally reorganized into the Centers for Disease Control on July 1, 1946, headquartered in Atlanta, Georgia. Three decades later, the same agency's virology division was where a sample from Central Africa ended up under an electron microscope. The CDC's founding mission was regional and wartime in scope; by 1976 it had become the reference laboratory fielding cables from missionary hospitals overseas.
