Condolence: so sorry to hear about Dolf. Its been maybe 5 or 6 years since I saw him but he was a great friend. I was at the Institute for Microstructural sciences in the late 80s early 90s in Ottawa and got to know him well. Before that we were both at Xerox in mississauga in the late 70s.. I was a student there and Dolf a postdoc. I really liked Dolf - we had the same twisted sense of humour. I made him laugh out loud many times… when my contract wasn't renewed at NRC in 92 I had a farewell pub night.. it was a small group but Dolf was there .. a great friend and colleague. Gone far far too soon...

Condolence: Dear Lyn; We are writing to express our sincerest condolences to you after learning of the passing of Dolf. We know this is an uncertain and emotionally difficult time for you. Our thoughts and prayers go out to you and the family. Though we did not know Dolf well we noticed a kind and gentle spirit in him, especially during your visit with us in Florida a few years back. We were surprised when we learned of his work as a principle scientist at N.R.C.. This was certainly influential and impressive. His memory will, no doubt, live on through you and the family. Grief is never easy. Please take care of yourself and your family and let us know of any information regarding the memorial that you may want to share. Love, Ann and Steve

Condolence: My deepest sympathy dear Carolyn. Dolf was such a good and kind man with a beautiful heart. I will always remember his dry wit, thoughtfulness and integrity. He was loved but many and will be dearly missed. You are in my thoughts. Xxoo Alison

Condolence: I was saddened today to hear about Dolf. I know it must be a tragic loss for you and your family and my heart goes out to you. I too feel a great loss since I have known Dolf for more than 50 years. We were both undergraduate students in Physics at the University of Waterloo and lived on the same floor in residence for those years. We got to know each other very well and formed a long lasting friendship. We lost touch for a number of years but eventually we both ended up at the National Research Council in the Institute for Microstructural Science. It was great to renew our friendship, talk over old times and to now have Dolf as a close research colleague. I have many fond memories of Dolf over the years, but the ones that always seem to be strongest and happiest are the ones from our undergraduate years at Waterloo. Perhaps in the future we can share our memories and reflect on how he has influenced so many.

Condolence: Please accept my condolences for your loss. I fondly remember Dolf from our days at Royal York Collegiate. One of my best memories was the day Dolf and I made nitroglycerin in his parents’ basement. When it erupted, we were all okay but his Mom’s laundry hanging on a basement line suffered badly. Clearly Dolf lived a rich and fulfilling life and leaves many enduring memories behind.

Condolence: Dearest Carolyn Please accept our sincere condolences for your loss. It must be such a difficult time for you. Please let us know if there is anyway at all we can be of help. Warm regards

Condolence: So very sorry Carolyn, to hear about Dolfs passing. Wishing you peace and comfort, sending thoughts and hugs, Christine B

Condolence: Dear Lyn - It's been a long year. Heather and I want to express our deepest condolences on your loss. We don't think we can ever remember seeing Dolf when he didn't have a smile. He always told great stories and laughed at his own jokes! Dolf will be missed by all. Please know that we are here for you during these difficult times. Love you always! David and Heather

Condolence: Dolf and I had a lot of fun together. He was a very pleasant and responsible man, well liked by everyone who knew him. He was a good husband, good father, and a good friend. One of his favourite spots was the Tiki Bar in Longboat Key. I think that waterfront bar on the beach was one of the main attractions that brought Dolf and Carolyn to Sarasota almost every year. Dolf was a frequent visitor to the tennis club primarily to meet Carolyn, enjoy a beer, and dine with his friends. Although Carolyn would frequently remind us that she needed to get home to give Dolf his dinner. Dolf played a significant role in planning a ZIP Line contemplated to run from Nepean point behind the national gallery to a point on the Quebec side. He would determine the required height and speed we would need to cross the Ottawa River and keep clear of boat traffic. He attended several meetings with me and the NCC. I was surprised when at our first meeting he showed up wearing a suit and tie. He brought a lot of credibility to the project. Dolf and Carolyn were a great team. One of our friends Art Dempsey would say Dolf slowed Carolyn down and Carolyn sped him up. We will miss Dolf.

Condolence: When we think about Dolf, we think of the Friendly Giant -an imposing "gentle man" who was full of original thoughts and imaginative ideas. He liked to express his opinions, comment on politics and discuss scientific topics ... or simply sit on the OTLBC veranda - have a drink, socialize, and laugh with friends. Dolf was always welcoming and kind, happy to have a house full of people at "the best" bar-b-ques and NYE parties that he and Carolyn regularly hosted. We miss him and his smile. We want to offer our condolences to Dolf's family - and our special thoughts to Carolyn. Linda and Andy

Condolence: Tom and I send our deepest condolences to Carolyn and to Dolf's entire family. Dolf will be greatly missed. His great love for Carolyn was there for all to see. He loved family and friends, and we spent many times at their home for dinner or a party. Dolf had a wonderful quircky sense of humour, and we enjoyed many good laughs. It was a pleasure to have Dolf and Carolyn visit us in Tobago,and I think he enjoyed our special island as much as we enjoyed having him visit. Dolf will be missed by family and friends, and his passing will leave a great hole in our lives.

Condolence: I will remember Dolf as a person who loved life and lived it to its fullest. He was an adoring husband, devoted father, accomplished scientist, a great friend and the best trivia player. He and Carolyn opened their hearts and home to everyone and I have the best memories of great parties and family celebrations on Flora Ave.. What struck me most about Dolf though were his strong family values. His greatest joy was spending time with Carolyn, Karl, Alex and extended family. He will be missed. My sincere condolences

Condolence: Condolences to you Carolyn on Dolf's passing. Carolyn you and Dolf were a lovely couple and it was heartwarming to see how much you cared for one another. I have fond memories of Wednesday evenings at the Ottawa South Tennis Club and all the lovely parties you hosted in your home.

Condolence: I have pleasant memories chatting with Dolf at the tennis club about our mutual Dutch heritage. He spoke fondly of his relatives there. As I have a younger cousin called 'Dolfie', I would tease him with that name and Dolf always tolerated it with his good-natured smile. Carolyn, you were such a strong and loving advocate for his care. My deepest sympathies.

Condolence: Lyn - There are not words to express, however please know that we are wishing you peace to bring you comfort, courage to face the days ahead and loving memories to forever hold in your heart. Lean on your friends and family for strength, and courage to face the days ahead. Our deepest sympathy to you and the Landheer family.

Condolence: Goodbye to the Dolfster and my deepest sympathies to Carolyn. I enjoyed our polite disagreements and will miss your infectious laughter. Gone too soon.....

Condolence: I did not know Dolph for very long. But when I first met him, I saw the kindest, sweetest and gentle soul in his eyes and heart and the love he had in his heart for his sweet wife Carolyn. I am thankful that he has crossed my path within our friend’s group and I send love and my condolences to Carolyn and all of the family. May God give you a special place by his side where you can share your wonderful stories with all the angels around you. RIP Xo

Condolence: I have fond memories of bike riding with Carolyn and Dolf along the Ottawa River and over to Aylmer Marina. Marching in the St. Patrick's Day parade as the Irish Cleaners Marching Band and goofing around all the way down Bank Street with plungers and mops for instruments. What a motley crew we were. Dolf was a very smart and interesting guy. He will be greatly missed. My condolences to his family.
