Sidney Thomas Spencer

Sidney Thomas Spencer Sr., a beloved husband, father, grandfather, great-grandfather, and proud United States Navy veteran, passed away peacefully on September 21, 2026 surrounded by the love of his family.
Sidney was born on April 24, 1934. His childhood was not an easy one. His mother, Mary White Spencer, died when he was very young, and after her death he was raised by his father, Thomas Spencer. His father struggled with his own demons, and eventually Sidney went to live with his grandmother. He experienced hardship and loss at a young age, including his brother Frank who developed polio at the young age of 19, and sadly, the illness eventually claimed his life. Over the years, he also became estranged from his sister Mary.
Those early years were difficult and left their mark on Sidney. Yet they also helped shape the strength, independence, and determination that would become such defining parts of his life.
As a young man, Sidney eventually left home and joined the United States Navy. He went on to serve his country for 23 years, building a remarkable career that took him and his family across the United States and around the world. Sidney was what the Navy called a Mustang--a service member who rose through the enlisted ranks and was later commissioned as an officer. He ultimately achieved the rank of Full Lieutenant.
During his military career, Sidney was stationed in places including Guam, California, Virginia, Florida, Rhode Island, Newfoundland, and Tennessee. He served in Antarctica, completed two tours of duty in Vietnam, and took part in other assignments that required him to spend long periods away from his family.
In 1954, Sidney married Irene Janet (Ellis) Spencer, the love of his life. Together they raised four children while following the demands and adventures of military life.
One of the family's most memorable Navy assignments was Key West, Florida. It was there that some of the stories Sidney loved to tell most were born.
Key West was where all four children learned to swim. Sidney believed in what the family jokingly called the "sink or swim" method. He took his children into the water and made sure they learned to swim. What might sound like an unusual lesson to parents today became one of those family stories that was remembered and laughed about for decades.
Key West also gave the family some of its greatest adventures. Sidney loved telling the story of how Donna would ride on his back and free dive underwater with him and hand-catch lobsters because they could hold their breath for so long. It was a story he seemed especially proud of and genuinely enjoyed telling.
When Sidney was home from his military assignments, he loved taking Irene and the children fishing. There were also trips for crabs, lobster, and shrimp. The family grew up eating the seafood they caught together--meals that would cost a fortune today. Fishing became one of the great traditions of the Spencer family and remained one of Sidney's greatest pleasures throughout his life.
And there was always room for a little family humor.
During those Key West years, Sidney made up a funny little song about his son, Sid Jr. It was one of those silly family songs that made Mom and Dad laugh, and eventually became part of the family's permanent collection of memories. Sid Jr. may not be particularly fond of the song today, but the family still remembers all the words. It is one of those funny pieces of family history that somehow never disappeared.
Those Key West years captured so much of what Sidney loved about being a father--the ocean, adventure, fishing, seafood, and having his children beside him.
His Navy career meant that Sidney was away from home for long stretches, but whenever he was home, he made memories with his family that lasted a lifetime.
While the family was stationed in Tennessee, they experienced one of the greatest tragedies of their lives. Sidney's beloved son, Dennis Neal Spencer, died from leukemia at the young age of 14.
Dennis's death changed Sidney forever. After his son's death, Sidney retired from the Navy following 23 years of service. He and Irene then moved to Pennsylvania, where Sidney began a new chapter of his life as a plant manager at Lafayette College. He eventually retired from the college as well.
After retiring, Sidney moved to North Carolina to be closer to his daughter Tommi Sue and grandson Cory. He spent many years supporting Cory's BMX racing, traveling to races and cheering him on. He also took great pride in teaching his son Sid everything he knew about electrical work, construction, and building.
Those skills were something Sidney shared freely with others, too. No matter where the family lived, Sidney was the neighbor people could turn to when something needed fixing or building. Whether it was electrical work, plumbing, construction, or simply figuring out how to solve a problem, he was always willing to lend a hand. He helped his neighbors with whatever they needed, often expecting nothing in return. Helping people was simply part of who he was.
Eventually, Sidney returned to Tennessee to be closer to his daughter Donna, his son Sid Jr., and his grandchildren. Those years brought many family gatherings, fishing trips, Thanksgiving and Christmas celebrations, and the laughter of grandchildren riding the go-kart Sidney bought for them.
Sidney's greatest love story was his marriage to Irene. They were married for 60 years, until Irene passed away from cancer on October 10, 2014. Her death left a tremendous emptiness in Sidney's life. He never stopped missing her.
Sidney was a strong-willed man who had lived through tremendous hardship. His difficult childhood made it hard for him to express his feelings, and the words "I love you" were not always easy for him to say. There were times when his struggles made life difficult for himself and those around him.
But underneath the toughness was a man who cared deeply about his family.
He made sure his children were provided for. He taught them what he knew. He helped his family when they needed him. He traveled to support his children and grandchildren. And throughout his life, he never let his family go without.
His love was often expressed not through words, but through actions.
As his health declined, Sidney eventually moved to Oklahoma to be closer to his son Sid Jr. and his family. He later moved to Brookdale Assisted Living and then to memory care, where he spent his final days.
Sidney was preceded in death by his beloved wife, Irene Janet Spencer; his son, Dennis Neal Spencer, who died of leukemia at age 14; his parents, Mary White Spencer and Thomas Spencer; and his brother, Frank Spencer.
He is survived by his three children: Donna Spencer Vance and her husband, Stephen Vance; Tommi Sue Keene and her husband, Kenneth Keene; and Sidney Spencer Jr. and his wife, Lisa Spencer.
He is also survived by his grandchildren: Brandy Miller, Heather Massengale (Eric), Drew Miller, Dennis Miller, Cory Muth (Bethany Harlan), Jeremy Keene (Rudi), Stephanie Hayes (Greg), Stephan Spencer (Kristan Kling), and Christin Carlisle (Scott).
His great-grandchildren include Spencer Groves, Olivia Groves, Zoe Lockhart, Gwyneth White, Alyssa Massengale, Jacob Spencer, Mathew Spencer, Kevin Spencer, Stephen Carlisle, Spencer Carlisle, Sidney Carlisle, Ellie Keene, Carter Keene, Caleb Keene, and Tucker Hayes.
Sidney lived a long and extraordinary life. He served his country, traveled the world, endured unimaginable loss, raised a family, taught his children and grandchildren, and made memories that will live on for generations.
He was not perfect, and he did not always know how to express what was in his heart. But he loved his family in the way he knew how--with determination, sacrifice, protection, and provision.
And perhaps now, after all these years, he can finally say the words that were sometimes so difficult for him to speak:
I love you.
He is at peace now, reunited with the woman he loved for 60 years, Irene, and with his son Dennis.
And as Irene once promised while she was nearing the end of her own life, she would keep the back door to heaven propped open for Sidney, because she knew he probably wasn't going to come through the front.
After a lifetime together, she finally gets to welcome him home.
Sidney will be cremated, and the family will lay him to rest beside his beloved wife, Irene, and his son, Dennis, in Lawrenceburg, Tennessee. A private service will be held for immediate family to honor his life and memory.
