Alfred (Al) Sommer is a prominent American ophthalmologist and epidemiologist at the Johns Hopkins Bloomberg School of Public Health. His research on vitamin A in the 1970s and 1980s revealed that dosing severely vitamin A deficient children with an inexpensive, large dose vitamin A capsule twice a year reduces child mortality by as much as 34 percent.[1] The World Bank and, recently, the Copenhagen Consensus list vitamin A supplementation as one of the most cost-effective health interventions in the world.[2][3]


Sommer was born in 1942 in New York City and graduated from Union College in Schenectady, New York in 1963. Sommer has an MD from Harvard Medical School (1967) and an MHS from the Johns Hopkins School of Hygiene and Public Health (1973). He is professor of Epidemiology and International Health at the Bloomberg School and Professor of Ophthalmology at the Johns Hopkins School of Medicine. He was dean of the Johns Hopkins Bloomberg School of Public Health from 1990-2005,[4] where he was instrumental in raising funding for an unprecedented expansion of the School's research and size.

Because of Sommer's vitamin A research, he has won the Albert Lasker Award for Clinical Medical Research in 1997[5] and the Danone International Prize for Nutrition in 2001,[6] among other honors.[4] The 2005 PBS documentary Rx for Survival featured Sommer as a "global health champion."[7]

Sommer became chair of the Lasker Foundation's Board of Directors in 2008.[8] He also serves on the corporate Boards of Directors of Becton Dickinson and T. Rowe Price.[9]

His current research involves the cause, magnitude, consequences, and control of vitamin A deficiency.

Sommer Scholars[edit]

In 2004, the Johns Hopkins Bloomberg School of Public Health established a $22 million scholarship program in honor of Dr. Sommer called the Sommer Scholars. [10] The programs aims to "recruit the next generation of public health leaders to devise new, effective interventions to improve global health."[citation needed]
