On September 16, 2015, the day of his 87th birthday, Dr. Robert H Marchessault died peacefully at the Sunrise Residence in Dollard Des Ormeaux QC after a lengthy and courageous battle with Alzheimer’s disease. Officer of the Order of Canada, Professor Emeritus at McGill and past vice president of Xerox Research Canada.

Dr. Marchessault was influential in the advancement of scientific research, he was the recipient of the Anselme Payen award (1976) and elected as a fellow to the Canadian academy of science (1982). His life was dedicated to his love of research. He was an ACS member for over 59 years and joined the Division of Polymer chemistry in 1970 and remained a member for 38 years. He had a passionate belief in education that is rooted in the rigors of a given
discipline, but that encourages individuals with inquiring minds to seek answers with creativity and in response to the needs of a rapidly changing world.

Dr. Marchessault leaves his friend, partner and wife of 63 years, Mary. Also left to mourn are his children: Robert (Theresa), Nicole, Claude (Denise), Janine (Phil), Kim (Suzanne) and Pierre plus ten grandchildren as well as his brother Doug (Norma) and his ex-son in law Pino Santilli. Many thanks go to the caring staff at Sunrise for their kindness to “Dr. Bob”.
