Who Was Robert True Houghton?
Robert True Houghton, also known as Bob Houghton, was an American aircraft engineer best known as Kris Jenner’s biological father.
He lived largely outside public attention and did not become a celebrity himself. Most available information about his life comes from biographies of Kris Jenner, family recollections, and historical family records.
One detail that has remained particularly meaningful to the family is his middle name, True. Kris later explained that the name came from her paternal grandfather, True Otis Houghton.
This family connection became widely discussed when Khloé Kardashian named her daughter True Thompson in 2018.
Early Life and Background
Robert True Houghton was reportedly born in 1931 in San Diego, California. His parents are identified in genealogical records as True Otis Houghton and Mary Lee Pickens, although detailed information about his childhood and upbringing is limited.
He spent much of his adult life in Southern California, where he eventually started a family with Mary Jo Campbell.
There is little independently documented information about his siblings, childhood experiences, or early personal interests. For this reason, specific stories about his upbringing should not be treated as established facts.
Education
Robert True Houghton’s formal education has not been clearly documented in reliable public biographies.
A 2026 account drawing on recollections from his former wife, Mary Jo, indicates that they met while attending college classes. However, the institution, his field of study, and whether he completed a degree have not been established.
His professional background is better documented than his academic history.
Career and Professional Life
Work as an Aircraft Engineer
Robert worked as an aircraft engineer, according to biographical coverage of Kris Jenner.
Although his occupation is identified, detailed records of his employment remain limited. His specific employer, engineering projects, and career achievements have not been widely documented.
He did not become a public figure during his lifetime, and there is little evidence of any involvement in the entertainment industry.
His professional identity is therefore best understood through his reported engineering work rather than unverified claims about business ownership or wealth.
Personal Life
Marriage to Mary Jo Campbell
Robert True Houghton married Mary Jo Campbell in 1954. Mary Jo later became widely known as Mary Jo Shannon and appeared on Keeping Up with the Kardashians alongside her famous family.
The couple had two daughters:
- Kristen Mary Houghton, known professionally as Kris Jenner.
- Karen Houghton, Kris’s younger sister.
Their marriage ended around 1962, when Kris was approximately seven years old.
Following the separation, Mary Jo primarily raised the two girls. She later married businessman Harry Shannon, who became an important father figure in their lives.
Relationship With His Daughters
Robert’s daughters were still young when their parents separated.
Kris Jenner was born on November 5, 1955, in San Diego, California. She later became a television personality, businesswoman, and manager of the Kardashian-Jenner family.
Her younger sister, Karen Houghton, maintained a considerably more private life.
Kris’s biological father should not be confused with her stepfather, Harry Shannon, or her former husband, attorney Robert Kardashian. These were three different people with separate roles in her family history.
Robert’s relationship with his daughters is not extensively documented. Some later accounts describe occasional contact during Kris’s adolescence, but details about their relationship remain limited.
Who Was Mary Jo Campbell?
Mary Jo Campbell, also known as MJ Shannon, was Robert’s former wife and the mother of Kris and Karen.
She was born on July 26, 1934, in Arkansas and later built her life in Southern California.
After her marriage to Robert ended, she married businessman Harry Shannon, who helped raise her daughters. She also established Shannon & Co., a children’s clothing boutique in San Diego.
Mary Jo became familiar to television audiences through appearances on the Kardashian family’s reality shows.
She died on July 16, 2026, at the age of 91.
Her life provides important context for understanding the family environment in which Kris Jenner grew up.
How Did Robert True Houghton Die?
Robert True Houghton died in 1975 following a car accident in Mexico.
His death occurred when Kris Jenner was 19 years old, long before she became a household name through reality television.
Some later accounts provide additional details about the accident, including claims involving a vehicle collision and a woman who was reportedly traveling with him. However, these details are not sufficiently established through independent historical records.
His death year and reported cause are more firmly documented than the precise circumstances.
Robert’s passing meant he never witnessed the international success of the Kardashian-Jenner family or the television career his daughter would eventually build.
Robert True Houghton’s Family Legacy
His Children and Grandchildren
Robert had two daughters with Mary Jo Campbell: Kris Jenner and Karen Houghton.
Through Kris, he became the maternal grandfather of six well-known personalities:
- Kourtney Kardashian
- Kim Kardashian
- Khloé Kardashian
- Rob Kardashian
- Kendall Jenner
- Kylie Jenner
Through Karen, he was also the grandfather of Natalie Zettel.
His family connection became especially recognizable after the name True returned to public attention.
The Story Behind the Name True
One of the most interesting details about Robert’s family history involves his middle name.
In April 2018, Kris Jenner publicly explained that her paternal grandfather was named True Otis Houghton and that her own father carried True as his middle name.
When Khloé Kardashian named her daughter True Thompson in 2018, the family name continued into another generation.
Kris expressed happiness about the choice because it honored an important part of her family’s history.
This connection is one of the clearest ways Robert’s name remains part of the Kardashian-Jenner family story.
Robert True Houghton’s Net Worth
Robert True Houghton’s net worth is not publicly established.
Although he worked as an aircraft engineer, there are no sufficiently reliable financial records detailing his salary, investments, property, or estate.
His daughter’s later financial success should not be used to estimate his personal wealth.
For that reason, no specific net-worth figure can be provided responsibly.
