John Emil Halver (April 21, 1922 – October 24, 2012) [1] was an American biochemist known for his research into the nutritional biochemistry, physiology, and cellular biochemistry of fish.[2] His work on the nutritional needs of fish led to modern methods of fish farming and fish feed production around the world.[3] He held a position with the United States Fish and Wildlife Service as director of the Western Fish Nutrition Laboratory in Cook, Washington, where Halver and his staff carried out research on the nutrient requirements for Pacific salmon.[4]
In addition to research, Halver taught at the University of Washington. Some of his students have become directors of federal fisheries programs, feed manufacturing plants, and university aquaculture programs. He was named Senior Scientist in Nutrition in 1975 and was US Science Ambassador 1975–1992.[6]
In 2005, Halver was named as one of the "Leading Scientists of the World" by the International Biographical Centre of Cambridge, England.,[7] because of his work for the Food and Agricultural Organization of the United Nations, the United Nations Development Program, the World Bank, the United States Agency for International Development, and the International Executive Service Corps, which led to improved food supply for populations in developing countries.[8]
Research
Halver discovered the cause of trout hepatomas (liver cancer) in the early 1960s, and developed methods of avoiding them.[9] He was voted into the National Academy of Sciences in 1978 on the basis of that work.[10]

Personal life
Halver was an active Christian, and gave lectures on the harmony between science and theology,[11] At the time of his death Halver was married to Jane Loren Halver (his wife of 68 years) and had 5 children: John Emil IV, Nancylee, Janet, Peter, and Deborah, 12 grandchildren, and 4 great-grandchildren.[1]
