There are many memories I have of Reb Yossel - Dr. Walder, from my early years in Iowa City, Dr. Walder was and continues to be a strong supporter of our Chabad House and all the work that we are doing.

One thing that sticks out is how Dr. Walder committed to something and he made sure to see it through. When I would visit his company out in coralville he was always so inviting and had time for me even though he was extremely busy the few days that he was in Iowa. This is really a drop in the bucket of what can be said of Dr. Walder of blessed memory.

Sending my sincere condolences to Mrs. Walder, Kathy, Moshe Chaim, and Mottel.

May Hashem remove all our tears and may we share in only Simchas

Please accept my heartfelt condolences to the Walder family on the passing of a much respected man. I am writing from Singapore and although my interactions with Dr. Walder were not for very long, it left a lasting impression on me and my team. Dr. Walder is an inspiration in how to treat people well, fairly and respectfully regardless of our standing or background. A truly great leader, by deeds and actions. Rest well Dr. Walder, you will never be forgotten, even in our part of the world.

I feel sad by hearing the news of Dr Walter’s passing.

Dr Walter has helped me a lot while I worked in his company. I clearly remember the time I spent with him and the conversations I had with him. I learned a lot from him. All of these are a great asset to me. Thank you very much, Dr Walder.

Please rest in peace. I would like to send my best wishes from far away Japan.

Many will write and speak about Dr. Walder's legendary kindness and generosity, and as a recipient of his kindness, I can attest to that as well.
What inspired me most about Dr. Walder was his Davening. Whenever I traveled to Chicago, I would attend the 9am minyan at FREE, where Dr. Walder was a regular. He davened with such humility and sincerity, each word in the siddur was a precious gem. the world stopped for him when he davened. Watching him was a textbook example of a chosid's davening .

After finishing, many would approach him with requests and advice, and it amazes me to this day how he had time for everyone. His selflessness and compassion left a lasting impression on me and countless others.

We are blessed to have known Yosef over the years, and were always impressed by his humility, warmth, kindness, and bitachon. He was a true baal chesed who has made the world a better place. זיכרונו לברכה.

Deepest condolences to Mrs. Walder and family.
I was fortunate to be able to meet Dr. Walder and also visited some customers with him when he was in Singapore. Always remembered how passionate he was during the discussion with some of the Professors on our visit to NUS and DUKE-NUS.
May his soul rest in peace!

As we mourn the loss of a leading Baal Chesed ZT"L...
From his place in Gan Eden he should be a Meilitz Yosher for Klal Yisrael in these difficult times.
