Rhinebeck – Sidney Thomsen, 87, a lifelong resident of Rhinebeck, passed away on December 2, 2025, at the Renaissance Rehabilitation Center in Hyde Park.
Born in Rhinebeck on May 10, 1938, he was the son of the late Marion (Bollenbecker) and Ejler P. Thomsen. Sidney attended Rhinebeck Central Schools.
Sidney worked for many years at Hubert Garage in Rhinebeck, where he sold tractors and handled repair work. He later spent over 30 years as a mechanic with Jon-Mar in Red Hook beginning in 1961. Known for his skill, reliability, and quiet dedication, Sidney took great pride in his work and the many friendships he formed throughout his career.
Sidney was the kindest, gentlest soul—someone who never complained and never had a bad word to say about anyone. His quiet warmth and sincere nature left an impression on everyone who knew him.
He was also predeceased this past summer by his beloved stray cat, Little Guy, whom he cared for over many years. Their companionship was a great source of joy and comfort to him, and he spoke often of Little Guy with affection.
He is survived by several cousins and close friends who will remember him for his kindness, loyalty, and lifelong connection to his community.
Calling Hours will be held at the Dapson Chestney Funeral Home, 51 W. Market St., Rhinebeck, NY on Monday December 8, 2025 from 3 pm to 5 pm.
A Graveside service will be held at the Rhinebeck Cemetery on Tuesday December 9 at 10 am.
