In Loving Memory of John “Jack” Leaf
July 19, 1924 – August 28, 2026
It is with heavy hearts that we acknowledge the passing of John “Jack” Leaf on August 28, 2026, at the age of 102.
Born on July 19, 1924, in the district of Kawehno:ke, Jack lived a life of hard work, resilience, service, and dedication to family and community. Growing up on Cornwall Island, he witnessed more than a century of change and carried with him a lifetime of memories, experiences, and stories. He attended Cornwall Collegiate and Vocational School (CCVS) in Cornwall and later married Adeline Hemlock, with whom he built a life filled with love, family, and cherished memories.
Jack's work ethic began early. At just 15 years old, he entered the ironworking trade, beginning a career that would span decades. He first worked in Buffalo and later on projects throughout New York State, gaining valuable experience and laying out the foundation for a lifetime in the profession.
From 1945 to 1947, Jack proudly served in the United States Army during the World War II era. During his military service, he completed much of his apprenticeship training, an experience that strengthened his skills and discipline as an ironworker.
After returning home from the Army, Jack resumed his ironworking career and went on to work across North America on bridges, shipyards, steel plants, and major construction projects. Throughout the years, his work took him from California to Connecticut and to countless job sites in between. He belonged to a generation of ironworkers who worked high above the ground with little or no fall protection, safety harnesses, or modern safety equipment, relying on skill, courage, and trust in their fellow workers.
A proud member of Ironworkers Local No. 6, Jack worked for many companies throughout his career, through long periods away from home. He remained dedicated to providing for his family while carrying the proud tradition of Mohawk ironworkers wherever his work took him.
Jack was recently recognized as both a centenarian and a United States Army veteran. As the last remaining Mohawk veterans of his generation, he was honored by the Saint Regis Mohawk Tribe, receiving a standing ovation in recognition of his military service, sacrifice, and lifelong contributions to his community.
Following his retirement from ironworking in 1987, Jack began a second career as Groundskeeper at Cedar View Golf Course in Massena, New York. For more than 20 years, he took pride in maintaining the course while enjoying one of his favorite pastimes, golf.
In his later years, Jack resided at Iakhihsohtha Lodge, where he became a beloved elder and friend. Known for his warmth, humor, wisdom, and storytelling, he was cherished by fellow residents, staff, family members, and visitors alike. His presence brought comfort, laughter, and companionship to many.
Jack will be remembered as a veteran, ironworker, family man, and respected community member whose life reflected determination, resilience, and perseverance. His legacy lives through the generations of family, friends, fellow ironworkers, and community members whose lives he touched throughout his extraordinary 102 years.
We extend our deepest condolences and prayers to his family, friends, colleagues, and all who had the privilege of knowing him. May they find comfort in the memories he leaves behind.
