Forever grateful for his encouragement, support and guidance throughout my doctoral journey

An inspirational leader who demonstrated, through professionalism and intelligence, the very best among scholars. His legacies are many and distributed. A 'nice guy' who finished first.

I recall interesting discussions with John , both on climate change and on the politics of BC and Canada. A knowledgable and engaging chap, with a fine mind and perceptive viewpoints, he had sometimes sardonic views on University politics in Canada, occasioning laughter and joviality. He will be missed by us all.

Dr. Grace was best teacher I had ever had. His teachings influence my daily life. He taught me a lot more than just academic knowledge. It is really sad to find the news from Linkedin today. I was thinking of him all since after graduation, although did not have chance to shake his hands, listen to his teaching and enjoyed his sharpness since. Such a loss. He was literally my family when I was at campus. My deepest condolences to his family which I never met. But I am sure everyone feels the pain as he is such such a great person...

Dr. John Grace is a very kind, patient and knowledgable supervisor. In my memory, he smiles all the time. Rest in Peace.

I did not know John well, but was a long time friend of some of his brothers and sisters. My condolences to all of the family in this trying time.

Almost 40 years ago I encountered John's famous textbook as an undergraduate at McGill. Since that time, we have crossed paths regularly on both academic and industrial pursuits. About 5 years ago, I had engaged John on a project, and instead of meeting at the University, he instead invited me over to his house, where we sat at his dining room table, discussing a fluidization issue. This personal touch and ability make one feel that their issues were important was what I will remember about John. He always made time for people, sharing his vast knowledge with anyone that could benefit from it. A true professional, and great person. I shall miss him.

My sincere condolences to Sherill. John taught me a number of undergraduate courses at UBC and he was also my PhD co-supervisor. John was the most humble man I had ever met in my life. I am going to miss him dearly as he was not just my PhD supervisor but he was a great mentor.  Poupak Mehrani

Claire and I remember John from our early years at UBC, 1992 on. He was a bright and brave soul, standing up for principles and equity. Sincere condolences from both of us, Sherrill. Susan B. Boyd and Claire F.L. Young

I will always remember John fondly for countless reasons. One of the first was his sense of humour. I will never forget when I first came to his office, his comment was ´a student just came out of the woodwork´. He boldly embarked on a research journey with me that was not within his regular bandwidth but he took it on with joy and energy and I will be forever indebted to him for supporting me through thick and thin during this journey. I proudly carry his torch of so many things that made him stand out amongst many many people. A true statesman, gentleman, ambassador, brilliant chemical engineer with a family name befitting of his personality. I will miss you terribly.

We all know John was a world renowned researcher, but what I truly respected most about John was his kindness and desire to help others. His legacy will live on through the many he has inspired.
