Barton David Kagan of Randolph, MA, on September 10, 2017.  Beloved husband of 62 years to his dear wife Barbara (Block) Kagan of Randolph. Cherished father of Phyllis Kagan Clayman and her husband Larry Clayman of Massachusetts, Rory Kagan and her husband Rafael Garces of Virginia, and Anita Kagan of Massachusetts. Devoted grandfather of Gregory Clayman of California, Julie Clayman of Massachusetts, Raquel Garces of Virginia and Renee Garces of Virginia. Adored brother of Richard G. Kagan ’60 and his wife Celia of Massachusetts and Florida. Treasured brother-in-law of Nelson E. Block and his wife Rhonda of Massachusetts. Revered son of the late Sidney J. and Mildred B. Kagan of Malden. Also survived by many nephews, nieces and cousins. Bart was a cum laude graduate of Williston Academy where he was a member of the Chess Club, Debate Club, the school newspaper and the school yearbook, as well as holding a state record in Track. He received his Bachelor of Arts from Yale University and his Juris Doctorate from The New England School of Law, where he was his class valedictorian. He had many interests, most notably anything to do with New England sports teams, which he followed with a zealous passion. There wasn’t a math problem he couldn’t solve, and a dog he didn’t love. He was a true family man and derived his greatest pleasure from his wife, children and grandchildren.
