Robert Dwyer Casey, Sr., 84, a lifelong resident of Bristol, passed peacefully Tuesday evening, November 23, 2021 at Bristol Hospital. He was the beloved husband of Anita (Bossi) Casey. Bob was born in Hartford on February 1, 1937 the son of the late George and Louise (Cashman) Casey. He served for 3 years in the US Army, mainly in El Paso, Texas. Bob graduated from Central Connecticut State University in 1962 and taught in the Bristol School System for 30+ years as an 8th grade language arts teacher at Bingham School, Hubbell School, Westwoods School and Memorial Boulevard Middle School before retiring. Bob & Anita loved to travel in their motorhome, in which they visited Alaska twice. They also made several cross country trips: first in 1977 with their three children, again in 2006 with Bob's sister Norky and brother-in-law, Michael, and again in 2011 with 5 of their grandchildren. Together Bob & Anita accomplished one of his "bucket list" goals which was to visit all of the US National Parks. He was also the President of the Cape Codders Family Motor Coach Association from 2004 - 2006. Among his many other interests was skiing, and Bob shared that love with many of his students when he ran the ski club for years at both Westwoods and Memorial Boulevard schools. He and Anita skied extensively throughout Vermont, Maine, most of the major western US & Canadian ski resorts, as well as several European resorts. Bob was also an avid hunter and fisherman, and a lifetime member of the Bristol Fish & Game Club, serving on the Land Trust Committee. After retiring, Bob & Anita spent 8 years as seasonal volunteers at The Saint Vincent National Wildlife Refuge in Apalachicola, FL. Bob was a handyman who loved to tinker and could take on any project, big or small. One of his many projects while serving at the Wildlife Refuge was building a bat house designed to hold 50,000 bats for conservation. Papa, we hope you're skiing down a mountain while shooting a deer!
