Dr. David Edward Mandeville
Dr. David Edward Mandeville, 84, passed away peacefully on July 13, 2026, while receiving comfort care at Freeman West Hospital in Joplin, Missouri, following a courageous journey with Stage IV metastatic melanoma brain cancer.
David was born on March 30, 1942, in Flint, Michigan, to Edward and Christine Mandeville, who preceded him in death.
Raised in Michigan, David built a life centered on curiosity, education, faith, and family. Throughout his career, he worked as an industrial engineer for several major companies across the Midwest before returning to Purdue University to earn his doctoral degree. He later joined the faculty at Oklahoma State University, where he served as a professor in the School of Engineering. Following his retirement, David and his beloved wife, Mary, made their home on the shores of Grand Lake in Grove, Oklahoma, where they found the peaceful life always dreamed of together. Looking out across the lake from their three-season porch became one of David’s greatest joys, and there was no place he would have rather called home.
An engineer through and through, David possessed an extraordinary ability to solve problems and create solutions. If something could be built, repaired, or improved, he was determined to figure it out himself. His hands and mind were rarely still, whether woodworking, tinkering around the house, or designing the next project, even right up until his last breath contemplating how devices in the ICU could be improved or fixed.
David found his greatest joy outdoors. He loved sailing across the water, flying his beloved Cessna after earning his private pilot’s license, caring for small planter gardens for Mary, and spending quiet moments appreciating God’s creations. Although he no longer flew later in life, aviation always remained close to his heart. He never stopped learning and loved talking “all things airplanes.” He treasured conversations with his close friends at the Pilot Coffee Club at Grove Airport. Those mornings, filled with coffee, laughter, and stories of flying, became some of his favorite moments.
At home, David enjoyed watching a good movie or sitcom, following fall college football, a recent love for European football and spending time with his beloved puppies and parrots, who never failed to make him smile.
More than anything, David made people feel heard. He listened with genuine interest, offered thoughtful advice, and gave those around him the gift of his full attention. Friends knew him as a quiet, humble man who deeply loved his wife, Mary, and whose steady presence brought comfort to those fortunate enough to know him.
David’s faith was a guiding force throughout his life. A devoted member of St. Andrew’s Episcopal Church in Grove, Oklahoma, he faced his final days with remarkable peace. Among his last words were simply, “I have hope”, a reflection of the faith that sustained him throughout his life.
David is lovingly remembered by his wife, Mary (Yarnell) Mandeville; his daughter, Laura (Mandeville) Pierce and husband Michael; his stepson, Tom McDonald; step-grandsons, Chad McDonald and Alex McDonald; his grandsons, Josh Pierce and wife Mary Vy Nguyen Pierce, and Nick Pierce and wife Allison Cruz Pierce; his great-grandchildren, Allison Mai Pierce and Harrison Phi Pierce; along with extended family members and dear friends.
He was preceded in death by his parents, Edward and Christine Mandeville, and his stepsons, Pete McDonald and Jeff McDonald.
The family extends its heartfelt gratitude to the compassionate caregivers at Freeman West Hospital ICU in Joplin, Missouri; Integris Health in Grove, Oklahoma; and the oncology teams in Grove, Oklahoma, Joplin, Missouri, and Miami, Oklahoma, for the exceptional care, kindness, and dignity they provided throughout David’s illness.
In keeping with David’s quiet nature, no funeral or celebration of life is planned. Instead, those who knew and loved him are invited to celebrate his life in their own way, perhaps by raising a glass in his honor, spending time on or near the water, tending to a backyard garden, looking toward the sky, or simply sharing a quiet conversation with someone they love.
David will be remembered not only for his brilliant mind, but for the quiet way he loved others. He listened more than he spoke, treasured his family and friends, found joy in life’s simple pleasures, and left those who knew him feeling valued because they had truly been heard. His final words, “I have hope,” remain a lasting reflection of the faith, humility, and grace with which he lived his life. Though he will be deeply missed, his legacy lives on in every life he touched, every problem he solved, every garden he planted, every flight he cherished, and every quiet act of love he so freely gave.
