    So sorry to here of Duke’s passing, I worked with Duke for over 15 years and boy the memories and the laughs I shared with him let alone his knowledge not only in the workplace but also outside of it of life in general and the stories he could tell. I have missed him in the last few years not being in the office almost every day even though he didn’t need to be and now I will enjoy fond memories and good laughs shared thru the years. Betty, he shared his love of you and spending well deserved time away from the office with his family as well. He remains a legend to many of us who had the pleasure of working with him and is remembered fondly.

  5. Very sad to hear of Duke’s passing. As many, I had the opportunity to work with Duke. When I first met him about 15 years ago, he seemed a crusty character, but immensely knowledgeable. Over the last few years, he softened but his wit and intelligence remained. His contributions to Alberta will live in the memories of those who knew him and will continue on in the many publications he authored. It was a privilege to have known and worked with Duke.

    I always felt that Duke was “indestructible” and would live to be a hundred! That’s why news of his sudden passing was indescribably sad; the world feels different without him. My favorite memory was playing lunchtime soccer with him in Clover Bar in the mid-1980’s. Duke was very special. He was my boss and my friend. We had many good times together. I will miss him greatly. My deepest condolences, Betty and family.

  13. Duke was one of a kind, and I admired and respected him (and liked him, too). I learned a tremendous amount from him while I was at AERI/AIEES. I was so sorry and shocked to hear he had passed, he always seemed indestructible. My condolences to his family. We will not see his like again; the world is a poorer place without him in it.

  17. Dear Betty and family,
    I am very sad to read Edmonton”s Journal this morning and see the passing of Duke. I am sure his passing is a great loss to you. I pray that the memories of happy times together and happy days together will comfort the sadness you feel.
    I will always remember how kind he was to me when I was a child, the informational talks I had with him when I came to visit you in Montreal 40 years ago and the conversation I had with him 3 years ago when I called to tell him about my dad, Victor’s, passing. I know that your family members who have gone on ahead and my parents were there to great him Saturday night. Tears and laughter are good ways to grieve and remember those we love who have passed on to the next journey. Sending you much love and many hugs.
    Your God daughter Diane and family.

  19. Dear Betty and family,

    I wish to express my heartfelt sadness on Duke’s passing.

    Duke and I were colleagues at the Alberta Research Council for about 20 years. During this period and beyond, Duke made contributions that now benefit all Albertans, especially through his scientific, technological, and organizational leadership for development of oil sands and coal resources. His approach was always insightful, principled, balanced, and respectful of others. But most of all, I remember and welcomed the kindness and warmth that he so capably weaved into our lives, and his sometimes cheeky chuckle.

    My sincere condolences. Brian Barge

    Mes hommages à Duke duPlessis. I have known him for over three decades. A sharp mind, he was able to integrate science, engineering and techno-economics of the energy field. He understood, probably better than anyone, the potential of Alberta as a stable provider of hydrocarbons (oil and gas) for Canada and the world. He also understood the challenges of Climate Change and the need to integrate “green energy” within the energy mix as a societal opportunity. His devotion to his cherished family and the remembrances of his huguenot ancestry were personal traits. His wisdom will remain.

I admired how much he knew and had accomplished and was inspired by how much he cared. I count it a real honor to have known Duke. He made a lasting impression on my life. We will continue to remember his family in our prayers.

  27. I was honoured and blessed to work with Duke for about 15 years. He was a mentor and friend. He was so patient in explaining science, processes, and strategy to me. No matter how many times I asked the same question, I was given a calm, reasoned, and thoughtful response. He was a blessing to us and Alberta.
