It was wonderful days in Joetsu with Yan and Kuriko. I (We) never forget those days and your memories. I would like to see you someday in heaven.

Dear Jan, your passing is so sudden. It has been a joy to be colleagues with you. You are so kind and will be terribly missed by everyone. Hope you rest in peace.

Dear Jan-san
We extend to you our heartfelt condolences.We are grateful to have met you through Kuriko. Your presence in our lives has brought immense joy and countless cherished memories. We hold great appreciation for you and your mother Kirsten. May your soul rest in peace.

I enjoyed learning from you - whether it was Physics, astronomy, or practicing Japanese and Danish together, I'll never forget your wisdom. May you rest in paradise and my condolences.

教えてくれて本当にありがとうございましたスタッフ博士｡ また会いましょう。

Du er den bedste lærer nogensinde. Tusind tak.

Your passing was so sudden. I'm still processing it. Thank you for being the kind individual you were and helping me when I most needed it. Rest in eternal Power

I am grateful for the time we worked together at LSU, Baton Rouge. You were always open to new ideas, willing to try again, staying positive, always with your unforgettable smile. You'll be missed.

親愛なるヤンさんへ、
シドニーでの楽しかった時間を忘れません。ありがとうございました。どうぞ安らかにお眠りください。

I am so glad and grateful that I got to work with you as much as I did, Jan. For your family and friends, I am so sorry for your loss. From my own perspective, Jan was always a joy to work with and I will miss him terribly.

Jan-san,

Thank you for all the beautiful memories. Your big smile always made me happy. I will not forget you!!

Dear Yan san,

Miss you so so much.
I feel so sad.

You will be remembered in our mind forever.

It was really nice meeting you and chatting in the office last year. It is so sad this happened so abruptly.
My deepest condolence to Kuriko and Jan's family for this loss.

Jan-san, it's hard to accept, but I believe you are peace in heaven. I'll forever treasure the moment we shared.
Thank you and Rest in peace.

Dear Jan, it's so sudden and unbelievable ! I hope you'll support and protect Kuriko form the sky forever. Rest In Peace, Ryoko Mizoguchi

It is surreal that I am at the stage in my career that we were at when you were co-supervising me in my Masters. You were such a lovely person to work with! You weren't condescending and made me feel like a collaborator. I have no doubt that you inspired many future scientists!

Jan, I've only known you for a short time, but it's been an honor to have known you. Nothing but honesty coming out from you and the presence you give will definitely be missed. You've done so well fighting, rest in peace.

Jan-san.
I want see you.

FUKU Chang.

Jan,
I don't know what should I say.
You were such a nice guy.
I had many good times with you.
I really miss you.
Sending my deepest sympathy.

I'm sorry to know that you have gone, Jan. You were always so kind and helpful to me. I hope you are at peace now.

Very hard to accept. After many years I still often recall Jan’s time here at Purdue – good science, earnest personal conversations (especially after a couple of drinks). Just recently we discussed a collaborative project – which will not happen...

Thank you Jan!
For being a great friend at Kampsax.
For teaching me the wonder in a Belgian beer on a snow covered bench with good company.
For letting me follow your travels in academia around the world.
For you and Kuriko meeting me in Copenhagen for a wonderful afternoon
RIP

Sorgen og gleden de vandrer til hope,
Lykke og ulykke kommer på rad. Medgang så ofte på motgang vil rope,
Solskinn og skyer de følges og ad.
Jorderiks gull er prektig muld. Himlen er ene av salighet full.

Jan. Thank you for many fun moments in and around the study period at Kampsax. I will miss your always good mood and your good stories. I often think back at that time and our trips together. Our thoughts go out to your family at this difficult time. R.I.P.
