Gary Lee Deets, 82, of Coventry, loving husband, father, and grandfather passed at Hartford Hospital Monday, February 16, 2026. Born in Sunbury, PA on February 28, 1943, the son of the late Willard and Ethel (Wagner) Deets. He grew up in Northumberland, Pennsylvania where he graduated from Northumberland High School, class of 1960. He went on to graduate from Bloomsburg Teachers College, earning his bachelor's degree followed by the University of Pittsburgh and earning his PhD in chemistry. Gary was employed by Monsanto in the specialty resins research department for 25 years. During that time, he met the love of his life, Julie Kuras, they married in 1981. Upon leaving Monsanto, he and Julie started a custom embroidery business in East Longmeadow MA which they ran together for a few years. Shortly thereafter, Gary re-entered the chemical R&D arena working with Industrial Summit Technologies (IST) located in Parlin, NJ for 20 years. Over the course of his life’s work Gary was named on 32 patents. The majority of his life’s work focused on consumer, industrial applications, and the aerospace and defense industries. He took great pride in the contributions he made during that time.
While growing up in Pennsylvania Gary loved to hunt and fish with his father and later with his son Gary (JR). He spent his summers as a child in Canada on Lake Dalhousie water skiing and fishing. He even loved to regale his friends and family with stories of the beautiful northern lights he was able to see while at Lake Dalhousie. In high school he played football, basketball, and baseball. In college he was on the chess team and a player not to take lightly. Gary worked at his father’s service station until 1970 when he moved to Springfield, MA. after graduating college. Being an adventurer at heart, he enjoyed traveling, camping, hiking, photography, and was quite the history buff. In his down time Gary was also known to be fond of watching sports and playing videos games to relax. He and JR would spend hours playing complex strategy war games. Gary traveled across the country with his family several times visiting the national parks and spent the last 35 years camping seasonally at Sebago Lake Family Campground in Standish, ME. He loved the peace and beauty of Maine and enjoyed many hours in the boat on beautiful Sebago Lake with family and friends. He was mindful of what great scenery the country had to offer.
Gary also treasured watching his sons excel playing soccer, running track, and wrestling. He loved being involved with his daughter Suzzy’s equestrian endeavors in her youth. Watching his Grandson, Nicholas, play soccer from the age of 5 through high school also brought him many years of joy. Gary was a very handy guy and would tackle any type of project and loved teaching his children the importance of being self-reliant and confident. We don’t think there was any task he found too difficult! After moving to CT in 1997 Gary became an avid UCONN women’s basketball fan as well as a season pass holder for the CT Sun women’s basketball team. Gary loved animals and they loved him. He has had many dogs, cats, and horses over the years.
Gary is survived by his beloved wife Julie of 45 years of Coventry; two sons, Gary Deets and his wife Serena of Willington, CT, Lee Deets and his wife Carol of Lenox, MA.;two daughters, Marsha Siman of Waterford, ME and Suzanne Deets of Groveton, NH.; 6 grandchildren; Nick, Ryan, Karley, Joey, Jerrie and Christopher.
