John David Clifford GRIMSHAW

GRIMSHAW, John David Clifford
It is with great sadness that we announce the unexpected passing of David Grimshaw on Tuesday, January 3, 2017. He was predeceased by his parents James and Josephine (nèe Siggins) Grimshaw, and leaves behind his loving wife, of 40 years, Roberta Imboden. David was born in Guelph on September 12, 1940, and attended North Toronto C.I. His lifelong passion was chess, and he was a Canadian Junior Chess Champion in 1959. He studied Mathematics, Physics and Chemistry at the University of Toronto, where he also earned a Master's degree in nuclear physics. David and Roberta were world travelers visiting Europe, China, Australia, South America and Cuba. Their trips were informed by their passion for social justice and David's masterful memory of history. He was a committed leftist, attending countless demonstrations with Roberta. He retained an avid interest in politics and world events, often recounting facts from the past with his own sly sense of humour. David was a well-liked professor at Ryerson University where he taught mathematics, physics and computer science. He will be sadly missed by his many friends and especially his colleagues at Ryerson. In lieu of flowers, David can be best remembered through donations to Parkinson's research, or a charity of your choice. The family will receive friends at the HUMPHREY FUNERAL HOME A.W. MILES - NEWBIGGING CHAPEL, 1403 Bayview Avenue (south of Davisville Avenue) from 5:00 to 7:00 p.m. on Tuesday, January 10th. A funeral service will take place on Wednesday, January 11th at 1:00 p.m. in the chapel. Condolences, photographs and memories may be forwarded through www.humphreymilesnewbigging.c om.
