John J. Dura

John J. Dura, who was world-renowned for his mathematical research, but more importantly was a deeply and wholly loved man with a gracious and humble heart, died in the arms of his family on New Year's Day 2026.

He grew up as a child of the Navy and the allure of the sea stayed with him his entire life. After spending his childhood in Hawaii, he moved to California for prep school and kept aiming eastward where he finished his undergraduate degree with the Jesuits at St. Joseph's University in Philadelphia. He completed his doctoral studies (also with the Jesuits) in theoretical mathematics at Fordham University in New York City.

Once ensconced on the East Coast, John met, fell in love with (at first sight) and married Mary, his beloved wife and partner in all things adventurous.

When his country called and the ocean beckoned, John took to the sea as a Naval officer and relished his time traveling to distant ports.

Once back on terra firma John began a life of service to others.  He was dedicated to feeding the hungry, assisting those who needed shelter, sharing Eucharist with the homebound, and mentoring newly minted mathematicians at AT&T. Then, when longed-for children graced his life, he enthusiastically picked up the mantle of coach, class parent, kite creator, doll house constructor, and sand castle builder extraordinaire--there simply was no end to the activities he would embrace to be with his daughters and to fully experience his role of "girl dad".

While his professional career constantly took him to the far corners of the Earth to teach others the mathematical models he pioneered in long-distance networking for telephone communication, he always made time for what was most important. Even when he was 11 or 12 time zones away, John made it his top priority to never miss one evening's phone call home to chat with his girls to discover what happened in the next chapter of Laura Ingalls Wilder's Little House books or hearing what Anne was up to amid those Green Gables.

John's interests extended through every genre of music and his prolific abilities in mastering instruments ran from the piano to violin to cello to banjo to saxophone. His home was always filled with copious amounts of love and music.

When illness reached him in mid-life, he bore long hospital stays and treatments with smiles, kindness and patience for all his many medical teams. Even in pain, he provided warmth and joy to legions of friends and colleagues—truly, he was simply a "good egg" and a man of deep faith who lived the gospel message in every facet of his life.

John lives on in the heart of his greatly loved wife, Mary, his beloved daughters Katie (Rich), Emily (Joe) and his very own posse of sidekicks (and frequent sleep-over guests) Brendan age 7, Sean age 7 and Colin age 5 ½ --all of whom delighted in sharing his hospital bed with him as he was under Hospice Care at home. The sound of their laughter as that bed zipped up and down filled John's heart with gladness and their joy fortunately still echoes in the hallways of our home.

Relatives and friends may call after 10:00 a.m. Wednesday, January 7, 2026 at Corpus Christi Church, 900 Sumneytown Pike, Lansdale, followed by the Funeral Mass at 11:00 a.m.  Luncheon follows immediately after at The William Penn Inn (just down the road).  Local arrangements are by the Huff & Lakjer Funeral Home, Lansdale.

In lieu of flowers, please follow John's life-long lead by continuing to generously share kindness with those in need—in doing so, you would make his heart smile.
