Early Years and Family Background
Gilbert Hartmann LaPiere was born on June 29, 1923, in Irvington, New Jersey. His parents were Albert LaPiere and Tillie Hartmann LaPiere, and they raised him in Newark. As a child, he was active in school, excelling in sports like track and baseball, and he earned the title of Eagle Scout. These early qualities of leadership and responsibility later shaped his military career and family role.
Military Service During World War II
In his twenties, Gilbert Hartmann LaPiere joined the U.S. Army Air Corps during World War II. He served bravely as a bombardier on B-24 planes, flying 35 missions across the Western Pacific. His unit often faced danger, including a harrowing ocean ditching after a bombing run. Many sources mistakenly call him a “Navy pilot,” but his official record shows he was in the Army Air Corps, which later became the U.S. Air Force.

His military service left a lasting mark. The courage and discipline he showed in war followed him into his civilian life. After the war, he returned home with experience, respect, and a vision for the future. For many, this phase of Gilbert Hartmann LaPiere’s life proved he was not only a stepfather figure but also a genuine war hero.
Education and Petroleum Engineering
After WWII, Gilbert Hartmann LaPiere studied Petroleum Engineering at the University of Missouri School of Mines in Rolla. The decision to enter this field reflected his interest in energy and finance. Graduating with strong technical skills, he stepped into a career that would connect him with major oil and banking companies. His education became the foundation of his successful business career.
Career in Oil, Banking, and Consulting
In the 1950s and 1960s, Gilbert Hartmann LaPiere built a strong career path:
- Worked for Cities Service Oil Co. in Bartlesville, Oklahoma as an evaluation engineer.
- Joined Chase Bank in New York City, where he handled oil and gas loans.
- Became part of W.E. Hutton & Co. on Wall Street, heading their Oil and Gas Department.
- Served as Vice-President at Union Bank of California, focusing on oil and gas projects.
By the mid-1960s, he shifted into being an independent oil and gas consultant. He moved to Oklahoma City in 1966, where he advised companies, solved financial challenges, and became known as a reliable troubleshooter.
Marriage to Georgia Holt
The most public part of Gilbert Hartmann LaPiere’s life began when he married Georgia Holt, an actress and singer, in the early 1960s. Their union not only gave him a wife but also introduced him to two young daughters: Cher, born in 1946, and Georganne LaPiere, born in 1951.
When the marriage took place, Gilbert made a life-changing choice. He legally adopted Cher and Georganne, giving them his last name and enrolling them at Montclair College Preparatory School in Encino, California. For years, the famous singer was officially known as Cher LaPiere, and her younger sister carried the same surname.
Becoming Cher’s Stepfather
Cher, who would later become one of the world’s greatest entertainers, was deeply influenced by the stability that Gilbert Hartmann LaPiere provided during her teenage years. While her early life with Georgia Holt had been full of ups and downs, Gilbert’s presence gave her a structured home and financial support.
His role as stepfather extended beyond just paperwork. He shaped her education, gave her guidance, and supported her dreams. Although their paths later diverged when Cher pursued fame, the impact of Gilbert Hartmann LaPiere remained visible. She carried his last name during her early rise in the entertainment world before legally changing her name to just Cher in 1979.
The Importance of Georganne LaPiere
The adoption also gave Georganne LaPiere, Cher’s younger sister, a sense of belonging. Georganne would later become an actress, known for her role as Heather Grant on the soap opera General Hospital. For her, Gilbert Hartmann LaPiere was not only a stepfather but the father who gave her identity and supported her first steps into acting.
This link is important because many fans search for “Georgianne LaPierre,” a spelling variation of her name. She represents how Gilbert’s decision to adopt left a lasting legacy for both sisters.

After leaving California, Gilbert Hartmann LaPiere settled in Oklahoma City, where he lived for decades. He enjoyed golfing at the Quail Creek Golf & Country Club and often spent summers in Linville, North Carolina. Friends described him as kind, generous, and deeply loyal to the people close to him.
