Mr. H. Clare Eatock

15 May, 192721 April, 2020

Henry Clare Eatock (Clare) was the beloved husband of Ruth, née Purdon; father of Brian Clare Eatock (Judy Keays), Ruth Anne Eatock (John Maunsell), and Lori Jane Forester (Gord Forfar); and grandfather of Alex and Ben Forester and Helen and James Maunsell.

Clare was born in Toronto to Meta Ellen (née Clare) and Harold Smithson Eatock, and was older brother to Bob (Irmgard), Albert, Bill (Pat), and Margaret (Peggy) Montgomery (Stan). His early years were financially constrained, especially after the death of his father in 1941, but Meta made sure that all five children got to university. Clare studied aeronautical engineering at the University of Toronto (class of 1948) and moved into a long and fulfilling career in gas turbine engine research, design and management at A.V. Roe and Orenda Engines (1948-1968) and Pratt and Whitney Canada (1968-1994). Clare’s love of work and sense of his own good fortune imbued his life with optimism. He and Ruth wed in 1950 and together made homes in Toronto (twice), Streetsville, Ontario, and St. Bruno, Québec. They formed deep and long-lasting friendships with colleagues and neighbors from all stages of their lives. In 1995, Clare and Ruth retired to North York, just down the street from Lori and her family, entering a phase anchored by school day lunches with much-loved grandsons and family gatherings at their cottage on the beautiful Moon River. Since 2018, Clare and Ruth have been cared for with kindness and competence at the Gibson Long-Term Care Residence in North York. Many have helped during these past few years; we especially wish to acknowledge the considerate and steadfast personal assistance of Fernando Caber, and Joseph and Lerma Morada.

We loved and remember our father for his sunny disposition, intellectual curiosity, and affectionate and constant embrace of life, work, friends and family.

No funeral is planned. Those who so wish may donate in Clare’s memory to the Alzheimer’s Society of Canada or a charity of their choice.

Helen and I were deeply saddened to hear of Clare's passing and send our deepest condolences.
Clare was my friend. We worked very closely together for the whole 22 years we spent at PWC. Not only did we have the same professional interests, but shared many personal interests, especially photography and HiFi. The first time I visited the family I was proudly shown a cabinet containing about two dozen red hot tubes, part of his new (pre-transistor) set up. Subsequent visits usually included a demonstration of his latest loud speakers, plus a waggy welcome from the beloved family dog, Maggie Mullins. Clearly, I was accepted into the family.
PWC has become the dominant company in the world of small gas turbine aircraft engines. As the manager of the Aerodynamics department he played a leading role in this success. Only an engineer can fully appreciate the work that he did; others can remember that in any airport in the world there will be an engine that bears his mark. This is also true of any commuter aircraft that you fly. It is one of the ways I remember him. Others will do the same.
He was my friend.

Clare Eatock . . . An Engineer from a past era.
During my tenure at PWC Longueuil, I was employed as a Project Engineer on the PW901A. It was circa 1988 that we had a failure of a baffle on the exhaust duct and Dr Colpin , Mr. I. Tremblay and I sought the advice of Mr Eatock to resolve . Within a 30 minute discussion we sketched out a potential redesign which was made through Experimental Engineering Modifications that same night and tested the following day. The fix worked. These gentlemen had a grass roots understanding of the system and calculated everything by hand. Clare was an Engineer from another era. He will be missed dearly as his passion to guide the younger engineers always resulted in you understanding the issue and when you got it, he would have a smile that said, there you go young man. Now do it. Keppel N Bharath

Chris and I were friends and neighbours of the Eatocks for almost 20 years on Craigmont Drive in North York. They gracefully accepted ourselves, our two sons and our various dogs into their home. We would sample their home made vintages often way too late into the evening and Clare, the dutiful host, would insist on walking us home, even though we only lived 3 houses away. The boys thought it appropriate to shovel his drive after a big snowfall, only to find Clare returning the gesture by assaulting ours during the next blizzard. He was kindness itself. A true gentleman with a ready smile and a hugely generous nature. You will be missed dear friend. Bless your heart Clare.

It was a pleasure and a privilege for me to have known and worked with Clare over many years, both at Orenda Engines and P&WC. As Chief Aerodynamics Engineer at P&WC,
he made important contributions to the development aircraft gas turbine engines. His technical expertise and professionalism were a fine example to his colleagues.
To Ruth and all his family I extend my deepest condolences.

I am sorry for the loss of Clare to his family and indeed to the world. I irregularly met Clare and Brian through the CASI organization. Clare was the consummate gentleman and when I would run into him his warmth and welcome were amazing. He made me feel like he was meeting a family member. He was a mentor and an example for an engineer, volunteer and fine human being.
I will continue to carry his fine traits forward and hopefully spread his spirit around.
I trust that his family will be sustained with amazing memories and see his traits and encouragement in each other.
