Roy L. Chapin, 86, died May 10, 2022, at home and surrounded by those dear to him after 22 years of Alzheimer’s Dementia. He was born March 10, 1936, in Baker, Mont., to Ralph Leighton Chapin and Sarah Maybelle (Goodwin) Chapin. After he was joined by siblings, George Ralph Chapin and Margo Ann Chapin, the family moved to Lewistown in the plain center of the state of Montana. This was where Roy, his two siblings, and cousins enjoyed growing up with plenty of outdoor adventures Montana style. Roy went on to study petroleum engineering at the University of Alberta, Canada, and worked in the oil fields of Nova Scotia during vacations. As soon as he graduated, he was drafted into the U.S. Army, where he served in the Secret Service at the German/Czech border for more than three years. While in Germany, Roy met the love of his life, Annelore Mann, married and brought her back to Montana. Their life together gave them three children and adventures in many foreign lands. Roy’s career took them to live in Argentina, the Caribbean Island of Trinidad, Cairo Egypt and Houston, Texas. Chicago was Roy’s choice of residence after an early retirement. In the 20 some years living with the slow decline of dementia, he still found pleasure and with concerts in Grant Park, biking along Lake Michigan, and get-togethers with friends.
