This club was formed to recognize the contribution of Dr. David Baker to the non-ruminant nutrition and to the American Society of Animal Science. Money from the club is used yearly to support the David Baker Amino Acid Symposium at ASAS Midwest Section Meeting.
Dr. David H. Baker has been one of the most productive animal scientists of our time. He has directed 36 Ph.D., 20 M.S., and 5 postdoctoral students. He and his research collaborators (mostly Ph.D. trainees) have published 455 papers in peer-reviewed outlets. He also has authored 280 abstracts and 200 popular articles. Recognitions for his accomplishments in nutrition research have been numerous. He has received six awards from ASAS, five from the Poultry Science Association, and two from the American Society for Nutritional Sciences. In 1986, Dr. Baker was the first faculty member in agriculture at Illinois to be given the title of university scholar, the highest honor attainable at the University of Illinois, and in 1987, he received the USDA Distinguished Service Award in Research. In 2005, he received the distinct honor of being elected to the National Academy of Sciences.
