Helen Maddock received her B.S. (1949) in animal science and her M.S. (1952) in animal nutrition from Iowa State College (University). As a student, Maddock participated in Block and Bridle Club and the Women's Athletic Association. While pursuing her graduate degree, Maddock assisted with swine research conducted by the Animal Husbandry Section of the Iowa Agriculture and Home Economics Experiment Station where she was involved in early research in antibiotics, vitamins, and protein requirements for livestock.

After graduation, Maddock worked as a Technical Writer in the Animal Feed Department of Lederle Laboratories, American Cyanamid Company, at 30 Rockefeller Plaza, New York, New York. Throughout her career with the company, Maddock held the positions of advertising manager, product manager, and program manager. As representative of American Cyanamid, Maddock attended the 1953 American Feed Manufacturer’s Association (later named the American Feed Industry Association) annual meeting in Chicago. She became a regular attendee and one of the only women to attend the AFMA Annual Meetings during her career.

Maddock joined the AFMA/AFIA Nutrition Council in May 1978, the first women ever to do so, as an Associate Member representing American Cyanamid Company. She participated on the Swine Research Committee to prepare "Review of Baby Pig Mortality" for the November 1978 Meeting (see Proceedings from 38th Annual Meeting). Maddock continued to serve on the Swine Research Committee until November 1982, when she joined the Poultry Research Committee.

On May 31, 1986, Maddock retired from the American Cyanamid Company resulting in her departure from the AFIA Nutrition and Executive Councils.

In addition to her work for American Cyanamid and AFIA, Maddock was very active in the agricultural livestock industry. Among other things, she helped establish the National Pork Queen scholarship, she served as the National Publicity Chair for National Agriculture Day, she was active in the National Agri-Marketing Association, and served on the editorial advisory board of Agrimarketing. In recognition of her long and productive career, Maddock became the first woman to be selected as an Honorary Fellow of the American Society of Animal Science.
