Hilary Stevenson

Hilary Stevenson (12 January 1947 – 5 October 1994) was a food scientist and professor from Northern Ireland who made significant scientific contributions to the study of food irradiation in the 1980s and 1990s.

Early life
Mary Hill (Hilary) Morrison was born in Coleraine, County Londonderry on 12 January 1947. She was the only daughter of James Stewart Morrison and Elizabeth Morrison (née Martin). She was raised at Drumaduan in the townland of Ballyrashane and attended Coleraine High School.

Education
Stevenson attended Queen's University Belfast where she graduated with first class honours in Chemistry in 1969 and Agriculture in 1970. She completed her M.Sc. in Food Science and Microbiology in 1971 from the University of Strathclyde. By 1981 she completed her doctoral studies, with her PhD dissertation focusing on metabolism of minerals by poultry.

Career
Stevenson joined the Department of Agriculture for Northern Ireland (DANI) after her undergraduate degrees, becoming an agricultural inspector. At this time she also lectured at the Loughry College of Agriculture and Food Technology. By 1974 she was promoted to senior scientific officer and had transferred to the Agricultural Chemistry Research Division. At this time she took up a position as university lecturer in the Department of Agriculture and Food Science at Queen's University Belfast.

Research contributions
In the early years of her research career, Stevenson focused on the vitamin content of peas before and after processing, later shifting her interest to the absorption of minerals by sheep. By the 1980s, her research had narrowed to poultry nutrition, publishing work on chickens and geese in UK agricultural journals such as British Poultry Science and the Journal of the Science of Food and Agriculture. Stevenson's most significant scientific contribution was her research on food irradiation, which she took up in the 1980s. She became an influential expert in the area, publishing over forty papers on the topic, collaborating with international partners on research studies, and organizing gatherings under the auspices of the United Nations. Her work or irradiation was recognized in 1993 when she was appointed to the Order of the British Empire (OBE).

Stevenson was an active member of several professional organizations, including the Northern Ireland branch of the Institute of Food Science and Technology, the Nutrition Society, the journal of British Poultry Science, and was a fellow of the Royal Society of Chemistry.

Personal life
She married Noel Stevenson in 1976 and the couple lived in Lisburn, County Antrim. She died at the age of 47 on 5 October 1994, after a prolonged illness.
