John Francis Power Jr. (affectionately called “Jack” by all who knew and loved him), age 84, passed away peacefully on Thursday, February 2, 2023, at his son's home in Winter Garden, Florida, surrounded by his loving family.  Born in Boston, Massachusetts on March 25, 1938, he was the son of the late John F. and Catherine (Hayden) Power.  He was raised in West Roxbury, Massachusetts, where he graduated from Roslindale High School with the Class of 1955.  Following his graduation, Jack enlisted in the United States Army Reserve, proudly serving his country while pursuing his bachelor’s degree at Northeastern College. Later, Jack continued his education completing his master’s degree in chemical engineering.


Jack married his beloved wife, Diane Gay, on October 5, 1963, at Saint Theresa's Church in West Roxbury.  Together they made their home in Dedham, Massachusetts before settling in East Walpole, Massachusetts.  Jack's career brought him to FM Global in Norwood, Massachusetts, where he served as a chemical engineer, working in the chemical plant fire and explosion protection division. During his long career he was very proud of his travels / adventures all over the globe. His travels included over 30 countries across 5 continents.


Jack was very likely the biggest Celtics fan the franchise ever had. He was recognized several times, center court, as the “Super Fan” and proudly maintained season tickets for more than 40 years.
