“…Dr. Henderson, who lived in Baltimore, died in a hospice of complications of a hip fracture, including infection with antibiotic-resistant staphylococcus, a dangerous pathogen he had himself researched and raised alarms about, said his daughter, Leigh Henderson.
Starting in 1966, Dr. Henderson, known as D. A., led the World Health Organization’s war on the smallpox virus. He achieved success astonishingly quickly. The last known case was found in a hospital cook in Somalia in 1977.
Long after the disease was officially declared eradicated in 1980, he remained in the field as a dean of what is now the Johns Hopkins Bloomberg School of Public Health and as an adviser on bioterrorism to several presidents.”
