Klaus Peter Spiegel, a 50-year resident of Newtown, passed away on May 21, 2025 from complications of Alzheimer’s disease, just twelve days prior to the passing of his beloved wife of 65 years, Marcia Barbara Spiegel.

Born in Berlin, Germany, on July 19, 1935, Klaus was the son of the late Ernst Spiegel and Charlotte Haenel Spiegel. He spent his early childhood during World War II, enduring the bombing of the city, the destruction of his family’s home and his father’s photography store, and the tragic loss of his brother, Heinz Bernd Spiegel, in a concentration camp. In 1949, at the age of 14, Klaus emigrated with his parents to the United States by ocean liner.

Arriving with limited English, Klaus taught himself the language and thrived in technical high school through perseverance, strong work ethic, and attention to detail. He went on to a successful career in drafting, product model making, and project management. He played a lead role in the creation of the New York City model for the 1964 World’s Fair, which remains on display at the Queens Museum and was later featured in the film Wonderstruck. Though highly respected professionally, Klaus often said his greatest accomplishment was his children.

On April 23, 1960, Klaus married the love of his life, Marcia Kayatt. He was a devoted husband and father, known for his kindness, willingness to help others, and quiet sense of humor — often marked by a twinkle in his eye and a knowing smile. Klaus and Marcia enjoyed boating and sailing on Candlewood Lake and sailing in the British Virgin Islands. Klaus was a valued and friendly presence at Candlewood East Club, where he gained many close friendships. Klaus also found joy in fixing things around the house and beyond, delighting in tinkering and lending his skills wherever they were needed.

Klaus is survived by his four children: Peggy Burg (Alan) of Seymour, Nancy Adams (Philip) of Southbury, David Spiegel of Thomaston, and Connie Zeller (David) of Freehold, N.J.; four grandchildren: Brandon Potter, Jason Adams (Lauren), Krista Adams, and Christina Spiegel; a great-grandchild, Sawyer Adams; a cousin, Renate Soybel; two nephews; and one niece.

Klaus will be deeply missed and lovingly remembered for his sense of humor, generosity, and devotion to his family.

A Celebration of Life for Marcia and Klaus was held at Candlewood East Club, Candlewood Lake, with family and close friends. In lieu of flowers, donations can be made to Alzheimer’s Association.
