In Memoriam Robert M. Kellogg
We regret to announce that Robert Macallan "Bob” Kellogg, died in North Vancouver, British Columbia, on May 7,2025, at the age of 93.Born on June 7, 1931, Bob devoted his professional life to understanding how trees become timber and how wood quality connects silviculture, processing, and performance in service.
He led Forintek’s Douglas-fir Task Force and edited the widely cited volume Second-growth Douglas-fir: Its Management and Conversion for Value (SP-32), which integrated knowledge on silviculture, juvenile–mature wood transition, yields, pulp properties, and structural performance. His work on forest management and end-product quality, and his co-editing of Structural Use of Wood in Adverse Environments, helped bridge fundamental wood science with practical engineering and product development.
In recognition of his lasting contributions, Bob was elected a Fellow of the International Academy of Wood Science and served as President of the Society of Wood Science and Technology (1974–75). Colleagues remember him as analytically rigorous yet modest, a clear thinker who could explain complex relationships—between juvenile and mature wood, density and performance, forest practices and product value—and a generous mentor to younger scientists. Bob’s scientific achievements were matched by his devotion to his family. He is lovingly remembered by his wife Betty, his daughters Kim, Kerry, Chris, and Julie, his five grandchildren, and his ten great-grandchildren. For all his professional recognition, he considered his family his greatest accomplishment.
At his request, no formal service was held for Bob. Those wishing to honour his memory are invited to do something he cherished: plant a tree, tend a garden, walk in the woods, or continue the work of using wood wisely and responsibly.
