Gilbert Hartmann LaPiere was an American petroleum engineer, financial adviser, and businessman whose professional life was closely connected to the oil and gas industry. Long before his name became associated with celebrity history, he built a career evaluating energy businesses, advising investors, helping companies arrange financing, and working as an independent consultant. His obituary describes a career that began in the oil business in 1947 and continued for many years in New York, California, and Oklahoma.
Today, however, Gilbert Hartmann LaPiere is primarily remembered as the former stepfather and legal adoptive father of Cher and her younger half-sister, actress Georganne LaPiere. After marrying their mother, Georgia Holt, he legally adopted both daughters. That decision changed their surnames to LaPiere and gave his name a lasting place in Cher’s personal and legal history.
His story therefore has two important sides. One is the life of a trained engineer, World War II airman, bank executive, and oil consultant. The other is the story of a man who became part of a well-known entertainment family and formed a legally recognized parental relationship with two daughters.
Quick Facts About Gilbert Hartmann Lapiere

Early Life In New Jersey
Gilbert Hartmann LaPiere was born on June 29, 1923, in Irvington, New Jersey. His parents were Albert and Tillie LaPiere. He attended grade school and high school in nearby Newark, where he participated in sports, particularly track and baseball. These details come from the obituary published after his death, which offers the clearest available account of his early years.
One of his notable childhood achievements was reaching the rank of Eagle Scout while he was still in grade school. His obituary presents this as an accomplishment of which he remained proud. It suggests that discipline, responsibility, and organized activities were important parts of his life from an early age.
His upbringing was far removed from Hollywood or the entertainment industry. His early life was shaped by New Jersey schools, athletics, scouting, and later engineering education. This background creates an interesting contrast with the celebrity attention his name would receive after he entered Cher’s family.
Education And The Impact Of World War Ii
LaPiere attended the University of Missouri School of Mines in Rolla, Missouri, where he studied petroleum engineering. However, World War II interrupted his college education for approximately two and a half years. Instead of completing his degree without interruption, he entered military service in the Army Air Corps.
According to his obituary, LaPiere became a bombardier on B-24 aircraft in the Western Pacific. He completed 35 missions and survived an incident in which his aircraft had to be ditched in the ocean after a bombing mission. This experience added a demanding military chapter to his life before he returned to education and began his professional career.
After the war, he returned to college and completed his degree in petroleum engineering. He was also a member of Sigma Pi fraternity and served as its president. Finishing his education was important because the degree prepared him for work that combined engineering, oil-field evaluation, banking, investment analysis, and corporate consulting.
World War II delayed LaPiere’s education, but it did not prevent him from following his original professional path. His return to college after military service marked the beginning of a career that would continue for several decades.
His Career In Petroleum Engineering And Business
After graduating, Gilbert Hartmann LaPiere began working as an evaluation engineer for Cities Service Oil Company in Bartlesville, Oklahoma. An evaluation engineer studies the technical and financial value of oil and gas reserves, properties, and business opportunities. The position requires an understanding of both engineering information and the financial risks involved in developing energy resources.
LaPiere later accepted a similar position with Chase Bank in New York City. There, he worked on oil and gas loans, mergers, and company sales involving major businesses and independent producers. His obituary states that he considered this the place where he truly learned the oil and gas business. The position moved him beyond engineering and introduced him to the financial side of the energy industry.
In 1952, he accepted responsibility for managing the Oil and Gas Department at W. E. Hutton and Company on Wall Street. His work included advising on oil and gas stocks and public offerings. Historical legal records also identify Gilbert LaPiere as being connected with W. E. Hutton during his work in energy finance.
After leaving Hutton, LaPiere became a vice president in the newly established oil and gas division of Union Bank of California. He eventually decided to work for himself as a financial oil and gas consultant. His consulting work included helping companies and independent operators improve their financial stability, complete mergers, or prepare their businesses for sale.
This career shows that LaPiere was more than a bank manager, as some short celebrity biographies describe him. His work combined petroleum engineering, investment advice, lending, company evaluation, corporate finance, and practical consulting across several parts of the American oil industry.
Marriage To Georgia Holt
Gilbert Hartmann LaPiere became connected to Cher through his marriage to Georgia Holt, an actress, singer, and model who was born Jackie Jean Crouch. Holt had experienced several marriages and periods of financial difficulty while raising her daughters and attempting to build an entertainment career.
Established accounts place LaPiere among her later husbands, following John Paul Sarkisian, Chris Alcaide, John Southall, and Joseph Harper Collins. He is therefore often described as Georgia Holt’s fifth husband when the men are counted in that order. The number can be confusing because Holt married John Sarkisian twice and had several marriages during her lifetime.
The most important result of her marriage to LaPiere was his decision to adopt her daughters. Cher was Georgia’s daughter with John Sarkisian, while Georganne was her daughter with John Southall. Gilbert legally adopted both girls and changed their family names to LaPiere.
The marriage between Georgia and Gilbert did not last for the remainder of their lives. LaPiere later married Beverly, and his obituary states that they were together for 34 years before her death in 1997. However, the legal adoption completed during his relationship with Georgia remained an important part of the family’s history.
Gilbert Hartmann Lapiere And Cher
Cher was born to Georgia Holt and John Paul Sarkisian. When Georgia married Gilbert Hartmann LaPiere, Gilbert initially became Cher’s stepfather. He later became her legal adoptive father, creating a more formal family relationship and changing her legal surname to LaPiere. Sources about Georgia Holt consistently confirm that Gilbert adopted both Cher and Georganne.
A stepfather becomes connected to a child through marriage to the child’s parent. An adoptive father becomes a legally recognized parent through the adoption process. Therefore, John Paul Sarkisian remained Cher’s biological father, while Gilbert LaPiere became her father through legal adoption.
There is limited reliable public information about the daily relationship between Cher and Gilbert. For that reason, claims that describe their bond in emotional or dramatic terms should be treated carefully unless they come directly from the family.
What can be confirmed is that the legal connection remained recognized. Cher was included among the daughters who survived LaPiere when his obituary was published in 2012. She appeared alongside Georganne and other members of his family.
The adoption is the main reason the name Gilbert Hartmann LaPiere continues to appear in biographies of Cher. Although his marriage to Georgia Holt was not permanent, his surname became part of Cher’s legal identity and remained there until she changed her name in 1979.
His Relationship With Georganne Lapiere
Georganne was Georgia Holt’s younger daughter and Cher’s maternal half-sister. Her biological father was actor John Southall, but Gilbert Hartmann LaPiere legally adopted her as well. This adoption explains why she became publicly known as Georganne LaPiere rather than continuing to use Southall as her surname.
Georganne later worked as an actress and appeared in television productions. Within the story of Gilbert Hartmann LaPiere, however, the most important detail is the legal family relationship. He did not adopt only Cher, who later became internationally famous. He adopted both sisters and gave both of them his surname.
LaPiere’s obituary used the spelling “Georgeanne Bartylak” and included her among the daughters he left behind. Other established biographical sources use the spelling “Georganne LaPiere.” Differences in spelling and married surnames sometimes appear across records, but the identity and family relationship are clear.
Georganne’s continued public use of the LaPiere name is another lasting sign of Gilbert’s connection to the family. While Cher eventually removed all of her surnames, Georganne remained widely recognized by the adoptive surname.
John Paul Sarkisian And Cher’s Biological Family
John Paul Sarkisian was Cher’s biological father. He and Georgia Holt became parents to Cher before their first marriage ended, and they later married each other again for a short period. Biographical accounts commonly describe Sarkisian as a truck driver, while Cher’s early upbringing was mainly shaped by Georgia’s efforts to support and raise her.
Sarkisian’s role in Cher’s family history was different from Gilbert LaPiere’s. Sarkisian provided Cher’s biological connection and original family surname. LaPiere entered her life later through his marriage to Georgia and became a parent through legal adoption.
Neither man’s role should be confused with the other. John Paul Sarkisian was Cher’s biological father, while Gilbert Hartmann LaPiere was her adoptive father and former stepfather.
This difference also explains why both surnames became part of Cher’s legal-name history. Sarkisian represented her family name at birth, while LaPiere represented the surname she received through adoption. Her marriages later added the surnames Bono and Allman.
Lynda Inez Gulley And The Wider Family Tree
Lynda Inez Gulley was Georgia Holt’s mother, making her the maternal grandmother of Cher and Georganne. The Encyclopedia of Arkansas identifies Lynda as Georgia’s mother and reports that she was very young when Georgia was born.
Lynda’s connection to Gilbert Hartmann LaPiere was indirect but still relevant to understanding the family tree. Gilbert married Lynda’s daughter Georgia and legally adopted Lynda’s two granddaughters. His place in the family was therefore created through marriage and adoption rather than through a biological connection.
Lynda also appears in the story of the first name Cher believed she had been given. According to the account in Cher’s memoir, Georgia said she had suggested the name Cherilyn by combining inspiration from Cheryl, the name of actress Lana Turner’s daughter, with Lynda, her own mother’s name. However, Cher’s birth certificate recorded her first name as Cheryl.
This wider family background helps explain the many names connected with Cher’s early identity. It also shows how Gilbert LaPiere became part of a family whose history involved several marriages, surnames, and parental relationships.
Why Cher Used The Lapiere Surname
Cher used the LaPiere surname because Gilbert Hartmann LaPiere legally adopted her. The adoption affected more than how the family was described socially. It added LaPiere to her legal identity. People reported that she assumed the surname after her stepfather adopted her in 1961.
The different names connected with Cher came from separate stages of her life. Sarkisian was linked to her biological father. LaPiere came through Gilbert’s adoption. Bono and Allman came through her marriages to Sonny Bono and Gregg Allman.
These were not simply stage names chosen for entertainment purposes. Each surname represented a biological, adoptive, or marital relationship.
The LaPiere name is especially important when researching Gilbert because it is the clearest lasting result of his place in Cher’s life. His marriage to Georgia Holt ended, but his surname continued to appear in Cher’s records and in accounts of her childhood. It also remained the best-known professional surname of her sister, Georganne.
This is why searches for Gilbert Hartmann LaPiere often lead to discussions of Cher’s legal name. His identity is connected to hers not because they worked together in entertainment, but because he legally became her adoptive father.
Cher’s 1979 Name Change And Memoir Revelation
In 1979, Cher decided to make “Cher” her complete legal name. During that process, she obtained her birth certificate and discovered that it listed her first name as Cheryl rather than Cherilyn, the name she had always believed was legally hers. She later described the discovery in Cher: The Memoir, Part One, which was released in November 2024.
According to the memoir account reported by People, Georgia Holt had experienced a long and difficult labor. When a nurse asked for the baby’s name, Georgia suggested Cherilyn, drawing inspiration from Cheryl Crane and her mother, Lynda. The document was instead completed with the first name Cheryl. Cher did not discover the difference until she began the legal name-change process years later.
When Cher changed her name, she removed four surnames: Sarkisian, LaPiere, Bono, and Allman. This decision turned her familiar stage name into her complete legal name.
Sarkisian came from her biological father, while LaPiere came from Gilbert’s adoption. Bono and Allman were the surnames of her former husbands, Sonny Bono and Gregg Allman. Removing all four allowed her to avoid being identified through a father, adoptive father, or former husband.
In a January 2025 television appearance, Cher confirmed that her driver’s license also carries only the name Cher. She explained that she had to establish in court that the public recognized her by that single name.
The memoir renewed interest in Gilbert Hartmann LaPiere because his surname was one of the four names Cher removed. For readers unfamiliar with her adoptive family, that detail naturally raised the question of who LaPiere was.
Gilbert Hartmann Lapiere’s Cause Of Death And Final Years
Gilbert Hartmann LaPiere died in Oklahoma City, Oklahoma, on February 7, 2012. He was 88 years old. His published obituary clearly records the date and place of his death but does not identify a specific medical cause.
For that reason, articles claiming to know Gilbert Hartmann LaPiere’s cause of death should be treated carefully unless they provide a reliable medical record or statement from his family.
The absence of a published cause does not suggest that anything unusual happened. It simply means that his family or obituary writer did not make that private information public. Therefore, the most accurate answer to the popular search query “Gilbert Hartmann LaPiere cause of death” is that no specific cause has been confirmed in the main publicly available obituary.
LaPiere spent many of his later years in Oklahoma City. He and his wife Beverly moved there from California in 1966, and he continued his oil and gas consulting work from Oklahoma. His obituary also mentions his enjoyment of golf, cruises, and summers at a mountain home in Linville, North Carolina.
Beverly died in 1997 after 34 years of marriage. LaPiere continued living in Oklahoma City until his death. A memorial service was held at All Souls Episcopal Church under the direction of Father Patrick Bright.
Memorial listings report that he was buried at Rose Hill Burial Park in Oklahoma City, although the main published obituary focuses on his visitation and memorial service rather than providing a detailed burial record.
Gilbert Hartmann Lapiere’s Place In Cher’s Family Story
Gilbert Hartmann LaPiere lived a life that extended far beyond his connection to a celebrity. He served during World War II, completed a petroleum engineering degree, worked in technical evaluation and banking, managed oil and gas investment activities on Wall Street, became a bank vice president, and advised energy companies independently.
His obituary presents him as a professional who spent decades helping businesses and individuals in the oil industry. His knowledge covered both the technical and financial sides of energy development, giving him a career that included engineering, lending, investment, mergers, and business consulting.
However, his place in popular culture comes mainly from his family role. By marrying Georgia Holt and adopting Cher and Georganne, he gave both daughters the LaPiere surname. That name became one part of Cher’s unusual legal identity and remained connected to Georganne’s public career.
The most balanced way to remember Gilbert Hartmann LaPiere is as both a serious oil-industry professional and an adoptive parent within Cher’s family. He was not Cher’s biological father, and the available public record does not support dramatic claims about their private relationship. What the evidence does show is a legally recognized family connection whose effect can still be seen in biographies, records, and Cher’s account of changing her name.
His story remains interesting because it sits at the meeting point of American business history and entertainment history. The engineer who spent much of his life evaluating oil and gas ventures also became part of the personal story behind one of the world’s most recognizable names: Cher.
