Samuel Grimley

GRIMLEY, Dr. Samuel Slater (PhD, Chemical Engineering)
National Research Council of Canada-IRAP Emeritus
August 10, 1921 - December 31, 2015

Samuel Slater Grimley died in Ottawa, Canada, on Thursday, December 31, 2015 in his 95th year. He was the second child of the late Gertrude Ethel Grimley (nee Fletcher) and the late Thomas Burton Grimley of Derwent Lane Farm, Wilne, Shardlow, Derbyshire, England, and husband of the late Anne Margaret Daunt Grimley (nee Golden, born in Toronto, 1922; married in Toronto, 1948, and died in Ottawa, 1985). Slater is survived by two daughters, Eileen Elizabeth Grimley of St. Thomas, Ontario, and Myra Wong and son-in-law Joseph Kwok Chun Wong of Ottawa, and brother, Professor Emeritus Thomas Burton Grimley of Parkgate, Wirral, England. Also predeceased by son, Thomas Daunt Grimley (d. Mont-Ste-Hilaire, Quebec, 1960) and sister, Dorothy Hazel Grimley (d. Castle Donington, England, 2009).

From humble beginnings in the rural midlands of England, Slater was a brilliant scholarship student throughout his studies, achieving a doctorate in chemical engineering from Imperial College, London, England, during World War II at the extraordinarily young age of 22. His long and distinguished career in science began during WWII at the Atomic Energy Research Establishment at Harwell, England (the main centre for atomic energy research and development in the U.K. from the 1940s to the 1990s) which seconded him to Canada in 1942. Sailing on the HMS Queen Mary, Slater would join a small team of scientists from around the world to carry out top-secret atomic research work at the Chalk River Laboratories in Ontario. In 1950, he returned to England to continue research at the Atomic Energy Research establishment at Harwell, England.

However, with difficult living conditions in post-war England, Slater returned to Canada in 1953 and embarked on a lengthy career in science research and management, first with a senior appointment at Canadian Industries Limited (C-I-L) in Montreal, Quebec, eventually being named Vice-President of Research, and finally to a seminal role with the Government of Canada in Ottawa creating and leading its longest running program – the Industrial Research Assistance Program (IRAP) – at the National Research Council of Canada (NRC). It is at the NRC where he retired with the prestigious title of IRAP-Emeritus.
For more than 20 years after his official retirement, until 2008, Slater remained a respected Guest Worker at the NRC advising on science policy for Canada and mentoring many.   Deeply interested in a wide variety of subjects, his favourites were economics, politics, classical music, reading, poetry, and soccer.

The family extends our heartfelt thanks to all his wonderful caregivers over the years, especially Onide Casimir, PSW. There will be no visitation. Interment at Beechwood National Cemetery of Canada. Friends and family are invited to attend a reception of remembrance in Ottawa in the spring, at a date to be determined. For details, contact:
