Dear Astrid, children, grandchildren and nearest friends. We are so sorry to hear of the loss of Rolf. When I reflect on my own career, and the extraordinary people I've had the privilege to work with, I realize how much Rolf gave to so many! I've had the privilige of discussing work-life balance with Rolf in his office many times and those 'Iessons' turned out to be as valuable as the technical stuff he tought me. A great mind and great man he was. His contribution to safety in the industry cannot be overstated and he will live on in our minds and hearts forever. Stay strong and care for each other... With love from Belgium, Jef and Wendy
I was lucky to meet Rolf, some 35 years ago, and he has ever since then inspired and encouraged me to work in the field of dust explosions. He was also a dear friend who has guided me through years with his wisdom. The world has lost an outstanding professional but above all a great person.
From the first time I heard him speak at a conference in the early 1980s, I was impressed by his wisdom and the passionate way he conveyed it. Years later we had the opportunity to organize a conference in Madrid for him, so that he could transmit his knowledge and experiences. And we were extremely lucky to spend time with him and enjoy the great human quality of him.
It has been an honor to meet him and to feel that, in addition to being a world reference in the field of dust explosions, he was also an excellent person.
Rolf told me he got a bad illness this Nov.24th on his birthday, but i never thought he goes so fast so that i have no time to be ready for hearing so mournful news.
Rolf is one of the most outstanding scientist and philosopher, His excellent book helped hundreds of thousands readers to be skillful on dust explosions in the world. He contributed all his talent and love to the world and human beings, especially to China and Chinas development of dust explosion research. It was in 1982, Rolf firstly invited Prof.Deng Xufan to visit CMR and make the first person to get to know dust explosions in China. Rolf gave Prof.Deng an original Hartmann bomb and some rare original manuscripts when she came back to China. Just because of the single spark Chinas research on dust explosions can have such a rapid expansion situation now. Rolf is my Ph.D international tutor, without his care and supervising it is impossible for me to get the degree, even this June we together published a paper in Chinese in Chinas Journal. He came to China more than ten times at his own costs as long as we invite and need his help. His going off make the world lost a great sage, you lost a best friend, but almost lost all for me!
Dear Rolf, just like what you said on your last email to me on Nov.24TH Christ will take care of me on the other side, you are a devotional Christian, every time Northeastern University gave you some teaching fee, you never keep one penny to Norway, you send all to my students and the God in Church, I am sure Christ must be able to fulfill his promise.
Rolf, though you pass away, but your knowledge will educate the coming readers, your help to China will be engraved in the monument of Northeastern University, your kindness and unselfish love to me and my family will be store in our hearts forever!
Bjørg og Jan Mangerud. Vi tenker på dere som sitter igjen. Håper det ikke blir altfor ting tid. 2022-01-04

Thank you for everything you have done both personally and professionally in your time with us.
I was only fortunate enough to meet you on a few occasions, but our discussions during those times (as well as reading dozens, if not 100s of papers and books from you over the years!) has greatly influence my direction in life and in my work - thank you.
Attached is a picture of me giving a presentation in Krakow in 2012. Right afterwards you (second back from my right) asked an excellent question about how to solve the challenges I was talking about - the answer to which honestly changed the direction of what I do today. Thank you
I will also always relish getting to see you play the trombone while your wife played the piano in Bergen. What a great dinner and conference - not to mention life you lived!
With kindess,
Chris & the DustEx Research Team
Takk kjære Rolf, for alle gode stunder sammen i Birkeland kantori. Din varme og sikre tenor, de morsomme og inspirerende talene på hver en korfest, og den gode praten i pausen som alltid etterlot et spor i sinnet, en ny tanke , en inspirasjon . Takknemlig for å ha kjent deg !
It is with extreme sadness that I learned that Professor Eckhoff passed away on Christmas day. Professor Eckhoff has been a pioneer in the field of explosion science and safety and has inspired many generations of engineers and scientists, including myself. His work has made the industry much safer and contributed to saving many lives around the World. His book "Dust Explosions in the Process Industries", especially, remains the absolute reference in the field of dust explosions several decades after its publication. Apart from his amazing scientific impact, Professor Eckhoff was a kind, dynamic and very approachable person. I have had the privilege to discuss with Professor Eckhoff during several editions of ISHPMIE, and I was always impressed by his sharp mind and knowledge. Professor Eckhoff, you will be deeply missed. Your legacy will live forever through your research and teachings. My sincere condolences to your family.
I met Rolf since the early beginning of my professionnal life 38 years ago and he occupies a significant part in my memory. Regards to all of you and in particular to his church. I will pray for him in my church (in Pont Sainte Maxence, France)
Signe minnet over ein flott, kreativ, klok, interessert og interresant mann. Me kjem til å sakne samtalar med Rolf. Vennleg helsing Margrethe og Leidulf.
Du var gjennom over 30 år nestor i gaten vår. Takk for godt naboskap med både gode og vanskelige samtaler. Jeg vil alltid huske din vakre tenor som lyste opp tiden i Birkeland kantori. Jeg husker også spesielt din glede da du fikk spille Body og Soul sammen med Knut. Hvil i fred, kjære Rolf.
