Condolence & Memory Journal

We miss our dear friend and neighbor here at Newbury Court, whose work with Jerry at the woodshop and friendship with us both always gave pleasure. Our condolences to the family and his many other friends.

I have known Klaus for many years via his work at Cambridge Acoustical Associates, a worthy competitor to BBN where I worked for nearly four decades. Although I also am a survivor of Nazi persecution, I never knew of his Jewish background. However, I did enjoy speaking German with him and often confronted him with "Raus, Klaus" ( "Raus" being a slang expression for "get out "). He always was gracious and friendly.
May he rest in peace and may his memory be a blessing to his family.

I first met Klaus in about 1959 when I was a co-op student working in the Raytheon Research Lab in Waltham. I enjoyed meeting and talking with him then. We each had professional careers working in acoustics but at different companies, me at BBN and him at Cambridge Acoustical Associates. I think that Klaus's invention of the acoustical absorbing concrete is a terrific idea and very useful.
We met again in the Concord Area Humanists, where Klaus was a very helpful and friendly presence. I will miss him very much.

Klaus arrived at Newbury Court shortly after we did, and soon became a good friend, although we must have encountered each other occasionally at contra dances previously. (He had supplied recommendations for acoustic treatment of the Concord Scout House, popular as a dance hall for decades.) It was disappointing to learn soon that he could no longer manage much contra dancing, and later that he couldn't steer a snowboard around a tree. We were disturbed to see Carol's decline, and saddened to hear of her passing. He was an eager woodworker, initiating some newcomers to use of the shop, and repairing and improving bits of our furniture. The few of us who joined him to read German enjoyed his humor and assistance, although his former teenage knowledge of the language sometimes also needed assistance. He served two years as Treasurer of the Residents Association, and was a committed member of the Climate Change Committee.

So sorry for your loss, Deirdre. I have many memories of your dad at birthday parties in your house on Elm Street. Big loss in a year of many losses and few hugs.
