 [John Hopkins Bloomberg School of Public Health] It is with great sadness that I write to let you know that Donald Ainslie Henderson, the eighth dean of our School, passed away last evening at Gilchrist Hospice Care. D. A. was a giant in public health who, prior to becoming dean, led the World Health Organization's successful 10-year effort to eradicate smallpox, one of the greatest public health achievements in history. Smallpox is the only human disease ever to have been eradicated. |
