John J. Diamont, Sr.

MARBLEHEAD - John J. Diamont, Sr., 93, of Naples, FL and Salem, MA died peacefully at Brigham and Women’s Hospital in Boston on May 15th. He was 93. Born on July 8, 1926 in Woburn, MA, John was the third child of Adam and Anna (Szawlis) Diamont. Although stricken with the polio virus as a child, he overcame it and many other obstacles to create a great life for his family. John was a born talker with charisma, good looks, intelligence, business sense, and an amazing head of hair until the very end!

John married Mary McEachern, also of Woburn, in 1947, and they had a fruitful and loving marriage. He graduated from Woburn High School and went on to begin his long career in the steel industry. John was a natural salesman, he could easily talk to anyone on almost any subject. With this talent and a lot of hard work he was able to build a business that he would be able to sell and retire from at the young age of 52.

He loved to travel and was an enthusiast of both boating & golf. He had a full and active social life which included memberships in many social and civic organizations. He was a member of the Tedesco Country Club and the Corinthian Yacht Club (where he served as Commodore) both of Marblehead. He was also a member of the Plantation Bay Country Club of Ormond Beach, FL, the Palm Beach Polo Club, the Knights of Columbus and the Elks Club. John was a communicant at Our Lady, Star of the Sea parish in Marblehead and St. Leo the Great’s Catholic Church in Bonita Springs, FL.

John was predeceased by his beloved wife, Mary. Their 59 years together were filled with love, laughter, children and a bond that many are not lucky enough to share. He is survived by his six children: daughter Mary and her husband David Danielson of Bedford, NH, son John and his wife Elly of Marblehead, daughter Chris and her husband, John Robinson of Kittery, ME, daughter Colleen of Salem, daughter Barbara and her husband Todd Smith of Califon, NJ, and daughter Jayne Diamont and her partner Mary Hubbard of Salem. He is also survived by eleven grandchildren and twelve great-grandchildren.

John will be deeply missed in body, but his spirit will always be in our hearts.

Because of the Covid-19 pandemic, funeral services will be held at a later date. In lieu of flowers, memorial contributions may be made in his memory to Our Lady, Star of the Sea Parish, 85 Atlantic Ave., Marblehead, MA 01945. Arrangements are under the care of Eustis & Cornell of Marblehead. To share a memory or offer online condolences to the family, please visit eustisandcornellfuneralhome.com.

My condolences to John Jr and your extended family. I enjoyed seeing John in the 19th hole for many years. Always had a smile and a good word.

I remember when he used to ride his bike around the neck when he was in his late 70's.

To the Diamont family, I'm very sorry to hear about John's passing. I am a member of TCC and work out in the TCC fitness center almost daily. ( hopefully it will open soon ) I was always amazed by John's grit and determination riding the stationary bike before going up to the 19 hole to have lunch. He did not let the disability he had stop or discourage him. I can still hear his distinctive voice say " hey there Tommy" as he came in to work out. He was truly an inspiration, and I'll miss him.

Your Dad was a remarkable man. I am so sorry for the pain that you are going through. I know that he will be missed as much as he was loved. I only hope you can find some peace in all of the wonderful memories you will have of him now. With Love, Sandy

My heartfelt condolences to you, Diamont family. I am so thankful to have decades full of wonderful memories of both your parents - from my first sailing experiences with your dad at the helm of the Jaybar out of Marblehead Harbor to countless examples of their generous hospitality in both their MA and FL homes, to your dad offering advice on a challenging work problem I was experiencing. Many years ago, when I first met him, I thought your dad had a bigger than life presence. Gregarious, witty and smart, it didn’t take me long to learn that he also had a very big heart. He and your mom were the definition of the perfect couple. What tremendous examples they set for love, working hard, enjoying life, and most significantly, the importance of family. I am so fortunate to have known them, and I will be forever grateful for the way they always made me feel like a part of theirs.
