In 1978 Janet Parker, a medical photographer at the UK’s Birmingham Medical School, worked one floor above the microbiology department, where smallpox research was being conducted. She became ill on August 11 but was not diagnosed with smallpox until nine days later. A subsequent investigation concluded Parker had been infected either through the building’s duct system or by visiting the microbiology department. She died on September 11, 1978, becoming the last known person to die of smallpox.
