Environmental health scientist Bailus Walker Jr. has been awarded the American Public Health Association's 1978 Edward W. Browning Prize for outstanding contribution to disease prevention.

The Browning Prize is presented annually in five fields: environmental conservation, improvement of food resources, prevention of disease, alleviation of addiction and spreading the Christian gospel.

Each of the five winners receives a $5,000 honorarium and a bronze Browning medal.

Walker, who has held several environmental health posts in administrative, academic and research capacities, is currently administrator of the D.C. Environmental Health Administration, Department of Environmental Services. He is an adjunct professor of environmental health at Howard University and a visiting professor of environmental medicine at Meharry Medical College.

The award cited his ability to define highly significant but often neglected environmental health sanitation and consumer protection problems.

Since 1975, Walker has served as a member of the Environmental Health Advisory Committee, Science Advisory Board, U.S. Environmental Protection Agency, and as an environmental health consultant to the Civil Rights Division of the U.S. Department of Justice.

In the last assignment, he has conducted extensive research into environmental health conditions and their effects on prison inmates. His findings have been published and have resulted in court-ordered improvements of correctional institutions.
