Gilbert Hartmann LaPiere was an American petroleum engineer, financial consultant, businessman and World War II veteran whose life connected the oil and banking industries with an unexpected chapter in entertainment history. Born on June 29, 1923, in Irvington, New Jersey, he became known to a wider audience partly because he legally adopted the future singer and actress Cher after marrying her mother, Georgia Holt.

However, his story extends well beyond that family connection. He served in the Army Air Corps during World War II, completed an engineering degree, worked with major financial institutions and eventually established an independent consulting career in the oil and gas industry.

He died on February 7, 2012, in Oklahoma City, Oklahoma, aged 88. His obituary provides a particularly detailed account of his professional journey, military experiences and family life.

Who Was Gilbert Hartmann LaPiere?

Gilbert Hartmann LaPiere was born into an American family in New Jersey. His parents were Albert J. LaPiere and Tillie Hartmann. He spent his early years in the Newark area, where he attended school and developed interests in athletics and scouting.

He later built a professional life around petroleum engineering, oil industry finance and business consulting. His work involved evaluating oil companies, financing transactions, mergers and business sales.

Although many modern searches for his name are connected to Cher, he had already established a substantial professional career before becoming part of Georgia Holt’s family.

Quick Facts About Gilbert LaPiere

These details are principally drawn from his published obituary and supporting genealogy records.

Early Life and Family Background

Gilbert was born in Irvington, New Jersey, on June 29, 1923. His parents, Albert J. LaPiere and Tillie Hartmann, are identified in genealogy records.

His childhood and teenage years were spent in New Jersey, particularly around Newark. He attended both grade school and high school in Newark, where he became involved in extracurricular activities.

One of the notable achievements recorded in his obituary was his attainment of the Eagle Scout rank while still in grade school. This was an early accomplishment that reflected his participation in organized scouting.

He also developed a strong interest in athletics. Track and baseball were among his main sporting activities during his school years.

These details provide a glimpse into his early life before his education, military service and professional responsibilities took him in a different direction.

Education at the University of Missouri School of Mines

After completing his schooling in New Jersey, Gilbert pursued higher education at the University of Missouri School of Mines in Rolla, Missouri.

He graduated with a degree in Petroleum Engineering, a field that would shape much of his professional career.

Petroleum engineering focuses on the exploration, extraction and production of oil and natural gas. However, Gilbert’s eventual career extended beyond the technical side of the industry.

His experience combined engineering knowledge with financial analysis and commercial decision-making. That combination became particularly valuable when he began working with banks and financial organizations involved in oil and gas investments.

His obituary also records that he was a member of Sigma Pi fraternity and served as its president.

His university education was interrupted by World War II, which delayed his studies by approximately two and a half years.

World War II Military Service

World War II was a defining interruption in Gilbert’s educational journey.

During the conflict, he enlisted in the United States Army Air Corps, the predecessor organization to the United States Air Force.

According to his obituary, he became a bombardier aboard B-24 aircraft operating in the Western Pacific theater.

His Experience as a B-24 Bombardier

The Consolidated B-24 Liberator was a long-range American heavy bomber used extensively during World War II. Bombardiers played an important role in bombing operations, helping aircraft crews deliver their payloads toward designated targets.

Gilbert reportedly completed 35 missions during his wartime service.

One particularly dangerous incident involved his aircraft being ditched into the ocean after a bombing mission. He survived the incident, an experience specifically mentioned in his published obituary.

His military service also explains why his university education was interrupted for two and a half years.

While the available obituary documents his branch of service, aircraft type, theater of operations and reported missions, it does not provide a detailed unit history or complete military service record. Those additional details should not be assumed without supporting military documentation.

Professional Career in the Oil and Gas Industry

After completing his petroleum engineering degree, Gilbert began working in the oil industry.

His professional journey developed from engineering evaluation into banking, investment analysis and independent consulting.

Rather than remaining exclusively in technical engineering, he built expertise in the financial side of oil and gas operations.

Work at City Service Oil Company

Following graduation, Gilbert joined City Service Oil Company in Bartlesville, Oklahoma, as an Evaluation Engineer.

The position provided an opportunity to apply his engineering education to the commercial assessment of oil and gas operations.

Engineering evaluations are important in the energy industry because companies and investors need to understand the potential value, financial viability and operating characteristics of oil-related assets.

His early experience in this role helped establish the foundation for his later work in financial institutions.

Career at Chase Bank in New York

Gilbert was subsequently offered a similar evaluation position at Chase Bank in New York City.

His responsibilities expanded into oil and gas financing, mergers and sales involving major companies and independent producers.

This was an important development in his career.

Instead of concentrating only on engineering assessments, he became involved in transactions and financial decisions that influenced how energy businesses were financed and operated.

His obituary describes this period as particularly valuable to his understanding of the oil and gas business.

Managing the Oil and Gas Department at W. E. Hutton & Co.

In 1952, Gilbert accepted a position managing the Oil and Gas Department at W. E. Hutton & Co. on Wall Street.

His responsibilities included advising clients on oil and gas stocks and public offerings.

The role placed him in a financial environment where technical knowledge of the energy industry could be combined with investment analysis.

His engineering background gave him an understanding of the businesses and assets involved, while his financial experience helped him evaluate commercial opportunities.

Vice-President at Union Bank of California

After his time at Hutton, Gilbert became a vice-president in the newly established oil and gas division of Union Bank of California.

This represented another important stage in his professional development.

His work continued to involve the relationship between financial institutions and energy businesses, particularly companies requiring industry-specific financial expertise.

The obituary does not provide a complete list of his transactions or the precise dates of every appointment, so his career should be understood through the documented positions rather than unsupported claims about individual deals.

Establishing His Own Consulting Business

Eventually, Gilbert decided to work independently as a financial oil and gas consultant.

His consulting responsibilities primarily involved helping companies and independent operators improve their financial stability, arrange mergers and complete business sales.

This type of advisory work requires an understanding of both the energy industry and the financial circumstances of individual businesses.

His combined background in engineering, banking and investment analysis provided a foundation for this work.

According to his obituary, he had been active in the oil business since 1947 and assisted companies and individuals in establishing businesses in Oklahoma and other states.

Gilbert LaPiere’s Marriage to Georgia Holt

One of the most widely discussed aspects of Gilbert’s personal history is his marriage to Georgia Holt, an American actress, singer and the mother of Cher.

Georgia Holt was born Jackie Jean Crouch. Before becoming widely recognized through her connection to Cher, she pursued her own interests in entertainment and had an established personal history.

In 1961, Georgia married Gilbert Hartmann LaPiere. Their marriage became an important chapter in the childhood of her daughters, particularly Cher.

His Connection to Cher

Cher was born on May 20, 1946, in El Centro, California. Her birth father was John Sarkisian, while her mother was Georgia Holt.

Following Georgia’s marriage to Gilbert, he legally adopted Cher and her younger half-sister, Georganne. The adoption changed their surnames to LaPiere.

This is why historical biographies and entertainment references sometimes identify the young singer as Cherilyn LaPiere or Cherilyn Sarkisian LaPiere.

The surname LaPiere therefore became part of Cher’s childhood identity, even though she later became internationally known simply as Cher.

This relationship is significant because Gilbert’s name appears in discussions about Cher’s family background, early identity and upbringing. However, it is important to distinguish his role as her adoptive father from that of her biological father.

The Guardian’s reporting on Georgia Holt’s life also confirms the marriage and the adoption of both daughters.

His Relationship With Georgia Holt

Gilbert and Georgia’s marriage was relatively brief. Public biographical accounts generally place their marriage in 1961, although some secondary databases show differing dates.

There is limited reliable public documentation about the private circumstances of their separation. Consequently, claims about the reasons for their divorce or the personal dynamics of their relationship should be treated cautiously.

What is documented is the lasting historical connection created through the adoption of Cher and Georganne.

Gilbert’s relationship with Georgia is an important part of his biography, but it represents only one period in a much longer life.

Gilbert LaPiere’s Family and Children

Gilbert’s family history includes biological, adoptive and stepfamily relationships.

His obituary, published in February 2012, provides the most useful account of the family members acknowledged at the time of his death.

The obituary names four daughters:

• Verna Bullock of Oklahoma City.

• Cher of Malibu, California.

• Georgeanne Bartylak of Ventura, California.

• Deborah Avery, who had died before him.

It also mentions Diana Spahn as a stepdaughter.

His grandchildren included Stacy Starchman, Kelly Hill, Christopher Borgen, Elisha Almond and Chas Bono, along with step-grandson Darren Lazarus.

These names demonstrate the size and complexity of his extended family.

His Parents

Genealogy information identifies his parents as:

• Albert J. LaPiere (1886–1951): His father.

• Tillie Hartmann (1897–1979): His mother.

The middle name Hartmann is consistent with his maternal family connection.

Ancestry also displays historical records associated with the LaPiere family, including census entries and family-tree information. However, the platform explicitly warns that user-submitted family trees can contain errors or change over time.

For genealogical research, original census documents, birth records, marriage certificates and official death records are preferable to relying solely on compiled family trees.

His Later Years in Oklahoma

Gilbert’s professional and personal life eventually became closely associated with Oklahoma.

After making repeated business trips to Oklahoma City from California, he and his wife Beverly moved there in 1966.

He continued his consulting work from the city and remained involved in the oil business.

Outside his professional activities, he developed an interest in golf. He became a member of Quail Creek Golf and Country Club, where he enjoyed playing for approximately 30 years.

Golf was an important recreational activity in his later life.

Gilbert and Beverly also enjoyed travelling together. They took cruises to different destinations and spent summers at their mountain home in Linville, North Carolina.

The cooler summers, golf and friendships they developed there became meaningful parts of their personal lives.

His obituary describes him as someone who valued relationships and maintained close friendships, including a particularly close connection with the Moore family in his later years.

His Marriage to Beverly

The obituary also records an important later chapter in his family history.

Gilbert and Beverly were married for 34 years. She died in 1997, preceding him in death.

This long relationship was distinct from his earlier marriage to Georgia Holt.

It is useful to make this distinction because online genealogy profiles sometimes combine multiple relationships without clearly explaining their chronology. The published obituary offers a more personal account of his later family life.

When Did Gilbert Hartmann LaPiere Die?

Gilbert Hartmann LaPiere died on February 7, 2012, in Oklahoma City, Oklahoma.

His obituary was published through The Desert Sun on February 11, 2012, and was also reproduced through Legacy’s memorial listings. Dignity Memorial provides another obituary record under the name Gilbert H. LaPiere.

His death marked the end of a life that had included military service, professional achievements, family responsibilities and decades of involvement in the American oil industry.

Funeral and Memorial Service

According to the published obituary:

• Funeral home: Hahn-Cook/Street & Draper Funeral Directors.

• Visitation: February 10, 2012, from 10 a.m. to 7 p.m.

• Memorial service: February 11, 2012, at 2 p.m.

• Church: All Souls Episcopal Church.

• Location: Oklahoma City, Oklahoma.

The family suggested memorial contributions to All Souls Episcopal Church, Habitat for Humanity or another charity of the donor’s choice instead of flowers.

These details help distinguish the official memorial arrangements from information repeated on secondary biography websites.

Why Is Gilbert Hartmann LaPiere Still Being Searched Online?

Interest in Gilbert’s name is largely connected to three subjects: Cher’s family history, his World War II service and his professional background.

1. His Connection to a Famous Entertainer

Cher is one of the most recognizable names in popular music and entertainment.

Because Gilbert legally adopted her during her childhood, his surname appears in historical references to her early identity.

People researching Cher’s family background may therefore encounter Gilbert’s name while exploring her relationship with Georgia Holt.

2. His World War II Experiences

His reported service as a B-24 bombardier and completion of 35 missions make his obituary relevant to readers researching American military history and wartime family records.

His survival after an aircraft ditching into the ocean is another notable detail that attracts interest.

3. His Professional Achievements

His career offers an interesting example of how technical education can lead to broader commercial opportunities.

He moved from petroleum engineering into financial evaluation, banking, investment advisory work and independent consulting.

That combination makes his professional history relevant to people researching the relationship between engineering and energy-sector finance.

4. Genealogy and Historical Records

People researching family ancestry may encounter different spellings and versions of his name.

For example:

• Gilbert Hartmann LaPiere

• Gilbert H. LaPiere

• Gilbert Hartmann Lapiere

• Gilbert LaPiere

These variations can affect search results and historical record matching.

When investigating family connections, it is sensible to compare birth dates, parents, locations and other identifying details instead of assuming that every similar name refers to the same individual.

How to Research Gilbert LaPiere’s Family History

Anyone interested in tracing his family background can start with the available obituary and genealogy records.

A useful research process involves several steps:

1. Start with the obituary: Use the 2012 memorial notice to establish his birth, death, career and named family connections.

2. Compare genealogy records: Check Ancestry’s historical record references, including census and Find a Grave index entries.

3. Verify family relationships: Look for original marriage and adoption records rather than relying exclusively on online family trees.

4. Check historical locations: Irvington, Newark, Bartlesville and Oklahoma City provide useful geographical starting points.

5. Keep separate family timelines: Distinguish his marriage to Georgia Holt from his later marriage to Beverly.

This approach helps prevent a common genealogy problem: combining information about different spouses, children or people with similar names into one inaccurate family profile.

Gilbert Hartmann LaPiere’s Life Beyond His Famous Family Connection

The most meaningful way to understand Gilbert is to consider his entire life rather than focusing exclusively on his association with Cher.

He was a New Jersey-born American who pursued an engineering education, served during World War II and developed a professional career spanning the energy and financial industries.

His work with City Service Oil Company, Chase Bank, W. E. Hutton & Co. and Union Bank of California reflects a career that combined technical knowledge with commercial and financial experience.

He also maintained interests outside work, particularly golf, travel and family relationships.

His obituary remembers him as a gentleman with a generous and loving nature, someone whose presence enriched the lives of family members and friends.

Although he was not a celebrity in his own right, his personal history remains relevant to people researching American oil industry professionals, World War II veterans and the early family history of Cher.

His story is ultimately a reminder that a person’s identity cannot be understood through one famous connection alone. Gilbert Hartmann LaPiere had his own experiences, achievements and relationships, all of which deserve recognition when documenting his life.
