Samuel Antonio Alsieux, 78, of Hillside, New Jersey, passed away on Monday evening, March 23, 2026, at Newark Beth Israel Medical Center.

Born on Friday, June 13, 1947, in Arroyo, Puerto Rico, to Samuel Benedicto Alsieux Alonso and Marie Elizabeth Colucci, Samuel was a man defined by his quiet courage, sharp instinct, and an unwavering resilience that carried him through a remarkable life. He was raised with the guidance of his step-father, Charles Levenson. Samuel is preceded in death by his parents, his stepfather, his brothers Gerardo Alsieux and Ronald James Alsieux, and his sister Aurette Murante. Those who knew him best describe him as sweet, with a very nice smile, and incredibly generous and thoughtful.

He answered his country’s call and was inducted into the U.S. Army as a Private in September 1966. Assigned to Company A of the 34th Armor Regiment—known as the "Dreadnaughts"—he entered Vietnam in January 1968, arriving at the onset of the Tet Offensive during one of the single deadliest years of the conflict. Tasked with one of the most perilous jobs in the military as a Motor Transport Operator and Mechanic, Samuel navigated dense jungles and hostile territory, driving the heavy, slow-moving supply trucks that served as the logistical lifeblood of the frontline forces. Operating daily in the crosshairs of enemy ambushes with minimal protection, he kept the engine of the military running with profound nerve and steady hands. He rose to the rank of Specialist 4 before concluding his active duty, and continued to honorably fulfill his commitment in the Army Reserves until September 1972. For his honorable service, he was awarded the Vietnam Service Medal, the Vietnam Campaign Medal, the National Defense Service Medal, and the Good Conduct Medal.

Translating the grit he forged in the military into the civilian world, Samuel became a cornerstone of the American heavy manufacturing sector. For two decades, stretching from the early 1970s into the 1990s, he worked across two American Cyanamid facilities in Linden and Clifton, New Jersey. Through sheer capability and dedication, he climbed the ranks to become the Supervisor of Maintenance. During the golden age of American manufacturing, Samuel was the industrial guardian of a sprawling, highly complex chemical operation. He led teams of mechanics and operators in a grueling, hazardous environment, responsible for the structural and mechanical safety of massive infrastructure. He oversaw the lines that produced heavy industrial resins and commercial cleaners at the Linden plant, as well as consumer-grade perfumes and iconic household staples like Old Spice, Breck Shampoo, and Pine-Sol at the Clifton facility. He was a man who understood how things worked from the inside out; he was the leader they depended on when the lines went down.

Beyond the factories and the front lines, Samuel was a devoted father who always made sure to provide for his family. He was a maintainer and a fiercely protective patriarch. David cherishes memories of his father spoiling him with an extraordinary amount of toys and video games, taking him to all-you-can-eat buffets, and perusing garage sales. Fond memories were also made on trips down the shore to visit Samuel's younger brother, Ronald, in Brick, New Jersey, where they would spend hours together walking the large local flea market. Samuel had a thoughtful affinity for keeping David's mother's West Orange home in pristine order; traveling from Hillside to spend summers landscaping and doing yard cleanups together with his son was not just a bonding experience, but a quiet demonstration of his ongoing care for his family's well-being. He loved discussing and learning about religion, and was incredibly adept at telling engaging stories that captivated his son and friends while growing up, powerfully teaching the stories of the Bible.

He is survived by his dedicated son, David, who stood by his side as his ultimate guardian through his final days; his daughter-in-law, Veronica; and his cherished grandson, Andrew, as well as another grandson expected in July, who will carry forward his legacy of strength. He is also remembered with enduring love and deep affection by his former wife, Barbara Alsieux; together they shared the blessing of their son, and she continues to hold Samuel dearly in her heart.

Following cremation, Samuel’s urn will be laid to rest with full military honors at the Brigadier General William C. Doyle Veterans Memorial Cemetery in Wrightstown, New Jersey, among his fellow brothers in arms.
