Dr. Albert Henn, 70, a public health official who was working on AIDS projects in Africa, was one of 114 people killed when a Kenya Airways jet crashed in Cameroon on May 5.
Henn, a former lecturer at the Harvard School of Public Health, and his wife, Kristan Schoultz, had lived in Africa for the last 20 years, working for healthcare and international development agencies.
Henn directed Kenya-based Liverpool VCT, which provides AIDS treatment and testing. Schoultz is the resident coordinator for the United Nations Development Program in Botswana.
Most recently, the two lived in different countries but visited each other often, Schoultz's father, Ture Schoultz, told the Press-Register in Mobile, Ala.
Schoultz said the two had taken many posts over the last 20 years, furthering AIDS education and prevention, improving hospitals and assisting with economic development.
According to the Boston Globe, Henn was a Peace Corps medical officer in Togo in 1968 before working for the U.S. Agency for International Development. He joined Harvard in 1983.
He worked in Egypt and Niger on medical projects after leaving Harvard.
