HAY, DONALD IAN, 82 years of Cambridge MA USA On July 10, 2016, our beloved Donald Ian Hay, 82, of Cambridge, MA passed away. Donald Hay is known for his outstanding science and acumen in saliva biochemistry, generous smile and witty sense of humor. Dr. Hay was Emeritus Senior Staff Member and an Interim Director at the Forsyth Institute, and Emeritus Professor at Harvard University, School of Dental Medicine. Dr. Hay received many honors and awards including an NIH Merit award and the Distinguished Scientist Award from the IADR for Salivary Research. Dr. Hay received his undergraduate education at the King’s school Peterborough and London University, UK. He served in the Royal Air Force Mountain Rescue, and was commissioned as a Lieutenant with the Royal Artillery (Territorial Army) UK. He immigrated to the US in 1965, and in 1972 received his PhD from London University, UK and in 1994 became an American citizen. Don had a life-long love affair with hiking, starting from his youth hiking in the mountains of Wales and Scotland and the Lake District in England, and subsequently in the US National Parks with a notable 2-week hike in the Grand Canyon. Don had an early interest in computers, built his own computer and helped run the CP/M group from 1980’s onwards. Don’s scientific interests began in childhood with construction of various explosive devices in his mother’s kitchen along with one or more of his 3 brothers, using materials “borrowed” from school. He was a chemist at Unilever (UK) before joining the Forsyth Dental Center (now Forsyth Institute) in 1965 on the recommendation of his life-long friend Irving Shapiro. In 1969, Hay became director of the Bioadhesion Department, which he chaired for the next 30 years. Among Dr. Hay’s major findings was discovery of a surface layer of proteins on teeth, the salivary pellicle, and characterization of saliva proteins statherin and the acidic proline-rich proteins (APRP). In groundbreaking studies Hay and co-workers identified and demonstrated the role of these proteins in preventing demineralization of dental hard tissues and in preventing calcium deposition on teeth although teeth are surrounded by a calcium-supersaturated environment (saliva). Equally notable was the outstanding work by Don and colleagues which showed that statherin and other proteins did not expose their binding sites for bacteria in solution, until attached to a surface such as a tooth (‘cryptotope’, which was a new concept). The subsequent delineation of the binding epitope to the C-terminal region of APRPs was very elegant and highly cited in the dental field and in biology in general. These novel findings helped bring the field of adhesion research to the molecular level, which required the innovation and skill in biochemistry demonstrated by Donald Hay. In retirement Don researched and published on the history of Clan Forsyth and their association with Griffins and enjoyed stargazing at the Harvard Observatory. Donald was born on November 5, 1933 in Peterborough, Northhamptonshire (now Cambridge), United Kingdom, son of George Henry Hay and Margaret Irene (Bellwood) Hay. He married Valerie Anne Butterworth of Boston MA (formerly Abingdon, Oxford, UK) in 1969 in Boston, MA. In addition to his beloved son, Ian Michael Hay of Atlanta GA, Donald is survived his siblings; Margaret Hay Wright of Deeping St. James, Cambridge, UK, John Brian Hay and Lesley Hay of Barton-on-Sea, Hampshire UK, Judith Irene (Hay) La Frentz and Robert John La Frentz of Chicago, IL, and sister-in-law Yvonne Hay of Hemingford Grey, Cambridge, UK, and Don’s sibling’s children, his nephews and nieces; Elizabeth, Ramona and Ursula; Margaret and Michael; Ian and Richard; Julie; Robert and Stephanie. Don is also survived by, and will be greatly missed, by his partner since 1999, Anne CR Tanner, her son Brian Worthington and his wife Kara. He was predeceased by his parents, his wife Valerie, sisters Alison and Frances, brother George and his wife Elizabeth, and brother Robert. A memorial is planned for October 7 at 11 am at the Mt. Auburn Cemetery, Story Chapel. Don requested that in lieu of flowers donation are sent to the National Parks Conservation Association (https://www.npca.org/give/more-ways-to-give) or to support the 2016 Walk to End Alzheimer's Greater Boston Walk - Cambridge, MA, 09/25/2016, team Rogerson House, leader Jennie Smith (http://act.alz.org/site/TR).
