Karl Robert Hahn passed away peacefully in his home on January 3, 2020 at the age of 89. Karl was born September 5th, 1930 in Wethersfield, CT. After growing up in Wethersfield, Karl served for four years as a Staff Sergeant in the US Air Force. A degree in Mechanical Engineering from Tri-State College (now Trine University) in Angola, IN enabled him to work as an engineer for 32 years at Pratt and Whitney Aircraft. His diligent efforts helped found and incorporate the Clinton Beach Association in 1967. As President of the Association for over 20 years, he was also the Acting Chief of Police. Karl was a member of South Congregational Church, in Hartford for over 60 years. Karl and his beloved late wife Jean of 54 years raised their family in Manchester and spent summers on the beach in Clinton where they welcomed friends and family to their cottage. Later, they avoided cold New England winters in their Florida retirement home. They also loved to travel and Karl had fond memories of his visits to 28 countries and 45 of our 50 states and Washington, DC. Most recently, Karl lived at The Residence in South Windsor. It afforded family and friends many wonderful visits, meals, memories, and special times. The staff all loved Karl, and we are extremely grateful for the wonderful care they provided.
