John Michael “Mike” Hart, 78, of Reading, formerly a longtime resident of Chelmsford, passed away peacefully on May 5, 2021 at home, surrounded by his loving family. He was the dedicated and beloved husband of Janet M. (Carr) Hart with whom he shared 55 years of marriage.

Mike was born in Lowell, MA on March 21, 1943, and was the son of the late Edward D. and Gertrude V. (Corkery) Hart.

He was raised in Chelmsford and was a graduate of Chelmsford High School, Class of 1960. He was a life-long fan of all his Boston teams. Mike worked at MIT Lincoln Laboratory for 43 years and had the opportunity to work on Kwajalein in the Marshall Islands. That special time on Kwaj was marked by amazing friendships and the chance to travel that part of the world with Janet. Upon retirement, Mike and Janet moved to Cape Cod where they enjoyed 12 years of fun, family, and friends. He loved golfing, and spending time at the Cape Cod Canal watching the boats and ships pass by or fishing with his granddaughters. When Mike and Janet decided to move to Reading, time by the canal was happily replaced with his granddaughters’ games, meets, karate classes and school performances. Whatever they did, “Pop” was there to cheer them on. His eyes lit up whenever his granddaughters, “The Fab Four” as he called them, were around.

In addition to his loving wife Janet, Mike is survived by his two daughters: Maureen Hart and Audra Cashin and her husband, Kevin Cashin, all of Reading. He is also survived by his four granddaughters: Sally, Emmy, Cathleen, and Erin Cashin. Mike leaves his siblings, Edward D. Hart, Jr. of Atlanta, GA, and Mary Jo (Brian) Stanton, of Chelmsford, MA; his sister-in-law Eleanor (George) McCarron of Clifton Park, NY; brother-in-law William Carr of Medford, MA; and many nieces and nephews.

He was predeceased by his brother-in-law, Frances J. (Anne) Carr and sister-in-law, Janet H. Carr.
