Arthur O’Quinn Walker Jr., 76, of Dallas, Texas, passed away peacefully on June 7, 2026. Art was born on September 5, 1949, in Natchitoches, Louisiana, to Arthur O’Quinn Walker Sr. and Mildred Louise Adkins Walker. He grew up in Shreveport, where he attended Fair Park High School before continuing his education at Louisiana Tech University. He then studied at the University of Texas, where he earned his master’s degree in petroleum engineering.
While attending Louisiana Tech, Art met the love of his life, Donna Lee Spargo. They married and shared 56 years together, building a life centered on faith, family, and service to others. Art faithfully served his country in the United States Navy for 20 years, retiring with the rank of Commander. Following his military service, he had a successful career in the oil and gas industry. He started as a petroleum engineer with John D. Caruthers, and ultimately partnered with Witt Caruthers to purchase Caruthers Producing Co., where he stayed until his retirement.
More than any title or accomplishment, Art was defined by his faith, his devotion to his family, and the quiet strength with which he lived his life. He loved Jesus deeply and demonstrated that love through humble service, unwavering loyalty, and steadfast commitment to those around him. He was a man whose actions spoke louder than words. Disciplined, loyal, kind, generous, selfless, hard-working, patient, and humble, Art lived his convictions daily.
After coming to know Christ, one of Art’s most treasured habits was rising early each morning to study God’s Word. His faith was not merely something he professed—it shaped the way he lived, loved, and served others. For more than 30 years, he faithfully served as a >deacon at First Baptist Bossier, investing in his church and encouraging those around him. Art’s greatest joy was his family. Known affectionately as Pops to his children and grandchildren, he rarely missed an opportunity to cheer them on. Across their variety of interests, he was there—quietly present, faithfully supportive, and genuinely interested in the lives of those he loved. Nothing brought him greater happiness than spending time with his family and watching his children and grandchildren thrive.
Art is survived by his beloved wife, Donna Lee Spargo Walker; his children, Todd Walker, Mark and his wife Hannah Walker, Lindsey and her husband Chad Hutchinson, Kelsey and her husband Jay Hills, and daughter-in-law Katie Walker; his grandchildren, Riley Walker, Jackson Walker, Presley Walker, Shea Walker, Chloe Walker, Isabella Walker, Justus Walker, Sky Walker, Isaac Hutchinson, Wyatt Hutchinson, London Hutchinson, Hyde Hills, and Remy Hills; and his siblings, Mickey Walker and Juana Walker.
He was preceded in death by his parents, Arthur O’Quinn Walker Sr. and Mildred Louise Adkins Walker, and his sister, Toni Sewell.
Art’s legacy is found not only in the family he loved so deeply, but also in the example he set through a life of faith, service, humility, and integrity. His steady presence, servant’s heart, and unwavering devotion to Christ will continue to inspire those who knew and loved him. He will be deeply missed and forever remembered.

Services will be held at Airline Baptist Church in Bossier City, LA, on Sunday July 19, 2026 at 2pm.
