Laurent Armand Beaubien

Laurent Armand Beaubien, affectionately known as Larry, passed away peacefully at home, enveloped in the love of his family, on April 17, 2026. He was 94 years old. Born on November 30, 1931, in Minneapolis, Minnesota, to Archibald George and Catherine Lawrence Beaubien, Larry lived a life that was as rich in love and achievement as the stories he so loved to tell. Larry spent his childhood in Falls Church, Virginia, where he nurtured a lifelong passion for learning. He graduated from Gonzaga College High School in 1949, and his academic journey led him to Catholic University, where he earned his Bachelor's, Master's, and Doctorate in Civil Engineering. His brilliance as a mathematician was evident, and it guided him toward a distinguished career at the U.S. Naval Research Laboratory in Washington, D.C. There, he authored numerous papers and worked on pioneering projects involving some of the world's first supercomputers. On June 14, 1958, Larry married the love of his life, Nancy Raffetto, at the U.S. Naval Base in Norfolk, Virginia. Their nearly 68-year marriage was a testament to enduring love and partnership. Together, they raised five children in Arlington, Virginia, close to Larry's parents, who were a vibrant part of their family life. Larry and Nancy returned to Falls Church in their later years, residing in the home that once belonged to Larry's parents. Larry was predeceased by his beloved son, Michael Lawrence Beaubien, whose memory he cherished dearly. He is survived by his devoted wife, Nancy Raffetto Beaubien, and his children: Jeanine Beaubien Colarusso, Terri Beaubien Ruggiero (Frank), Robert Charles Beaubien (Donna), and Kathryn Beaubien Solomon (Scott). He also leaves behind seven grandchildren: Eric, Glen, Corwin, Joseph, Allyson, Elliott, and Jacob, each of whom he adored deeply. Beyond his professional accomplishments, Larry was a man of many passions. An avid golfer with a nearly perfect handicap, he spent countless sunny days on the golf course, winning numerous tournaments and contemplating a professional career. His love for music and stories was reflected in his vast collection of books and records, and he often entertained family and friends with his skills as an amateur magician. With a nearly photographic memory, Larry's recollections of his childhood and adolescent years were vivid and detailed, and he delighted in sharing these stories with anyone who would listen. Larry's greatest joy came from his family, whom he considered his most significant achievement. He found profound happiness in the company of his children and grandchildren, relishing in their laughter and stories. His warmth, wisdom, and humor will be deeply missed by all who had the privilege of knowing him. A funeral service to honor and celebrate Larry's remarkable life will be held on May 1, 2026, at 10:00 a.m. at St. James Church, located at 905 Park Avenue in Falls Church. Family and friends are invited to gather in remembering a man whose life was a testament to love, dedication, and an enduring spirit. In lieu of flowers, the family requests that donations be made in Larry's memory to a charity of your choice, reflecting his generous spirit and commitment to making the world a better place.
