Donald Ainslie Henderson (September 7, 1928 – August 19, 2016) was an American physician, educator, and epidemiologist who directed a 10-year international effort (1967–1977) that eradicated smallpox throughout the world and launched international childhood vaccination programs.[1] From 1977 to 1990, he was Dean of the Johns Hopkins School of Public Health.[2] Later, he played a leading role in instigating national programs for public health preparedness and response following biological attacks and national disasters.[3] At the time of his death, he was Professor and Dean Emeritus of the Johns Hopkins Bloomberg School of Public Health, and Professor of Medicine and Public Health at the University of Pittsburgh, as well as Distinguished Scholar at the UPMC Center for Health Security.[4][5][6]
Early life and education
Henderson was born in Ohio.[7] His father, David Henderson, was an engineer; his mother, Eleanor McMillan, was a nurse. His interest in medicine was inspired by a Canadian uncle, William McMillan, who was a general practitioner and senior member of the Canadian House of Commons.[8]
Henderson served as Chief of the CDC virus disease surveillance programs from 1960 to 1965, working closely with epidemiologist Alexander Langmuir. During this period, he and his unit developed a proposal for a United States Agency for International Development (USAID) program to eliminate smallpox and control measles during a 5-year period in 18 contiguous countries in western and central Africa.[9] This project was funded by USAID, with field operations beginning in 1967.[8]
The USAID initiative provided an important impetus to a World Health Organization (WHO) program to eradicate smallpox throughout the world within a 10-year period. In 1966, Henderson moved to Geneva to become director of the campaign. At that time, smallpox was occurring widely throughout Brazil and in 30 countries in Africa and South Asia. More than 10 million cases and 2 million deaths were occurring annually. Vaccination brought some control, but the key strategy was "surveillance-containment". This technique entailed rapid reporting of cases from all health units and prompt vaccination of household members and close contacts of confirmed cases. WHO staff and advisors from some 73 countries worked closely with national staff. The last case occurred in Somalia on October 26, 1977, only 10 years after the program began.[8] Three years later, the World Health Assembly recommended that smallpox vaccination could cease. Smallpox is the first human disease ever to be eradicated.[10] This success gave impetus to WHO's global Expanded Program on Immunization, which targeted other vaccine-preventable diseases, including poliomyelitis, measles, tetanus, diphtheria, and whooping cough.[11] Now targeted for eradication are poliomyelitis and Guinea Worm disease; after 25 years, this objective is close to being achieved.[6][12]
Later work
From 1977 through August 1990, Henderson was Dean of the Johns Hopkins School of Public Health. After being awarded the 1986 National Medal of Science by Ronald Reagan for his work leading the World Health Organization (WHO) smallpox eradication campaign, Henderson launched a public struggle to reverse the Reagan administration's decision to default on WHO payments.[13] In 1991, he was appointed associate director for life sciences, Office of Science and Technology Policy, Executive Office of the President (1991–93) and, later, deputy assistant secretary and senior science advisor in the Department of Health and Human Services (HHS).[8] In 1998, he became the founding director of the Johns Hopkins Center for Civilian Biodefense Strategies, now the Johns Hopkins Center for Health Security.[4]
In 2006, Henderson co-authored a paper in which the authors were skeptical of several potential pandemic measures, including social distancing: "Many could result in significant disruption of the social functioning of communities and result in possibly serious economic problems. Such negative consequences might be worth chancing if there were compelling evidence or reason to believe they would seriously diminish the consequences or spread of a pandemic. However, few analyses have been produced that weigh the hoped-for efficacy of such measures against the potential impacts of large-scale or long-term implementation of these measures."[17]
At the time of his death, he served as the Editor Emeritus of the academic journal Health Security (formerly Biosecurity and Bioterrorism: Biodefense Strategy, Practice, and Science).[18]
Seventeen universities conferred honorary degrees on Henderson.[37]
