Gladys Pearl Monroe (May 27, 1902 – March 11, 1984), also recognized as Gladys Pearl Monroe Baker Mortensen Eley, was the parent of Marilyn Monroe (born Norma Jeane Mortenson). Gladys was born in Mexico, raised in Los Angeles, and encountered numerous personal challenges, including mental health issues and instability. She contributed to early Hollywood as a film negative cutter and movie editor, managing film reels during the silent and early sound periods.
Gladys married thrice and had three offspring, among them Marilyn Monroe. She endured various difficulties, such as losing relatives, experiencing abusive relationships, and severe mental health issues that necessitated long-term stays in psychiatric facilities. Gladys frequently found it hard to maintain stable housing and employment, at times relying on friends, family, and later Marilyn for support. Her life comprised episodes of poverty and alcoholism, and her relationship with Marilyn was strained. Marilyn spent time in foster care and orphanages due to Gladys’s inability to care for her. Nonetheless, Gladys and Marilyn maintained some form of communication, and Marilyn later provided her with financial assistance.

Gladys Pearl Baker Biography
Gladys Pearl Monroe was born on May 27, 1902, in Porfirio Díaz (presently Piedras Negras), Coahuila, Mexico, close to Eagle Pass, Texas. Her mother, Della Mae Hogan Monroe, hailed from Missouri, while her father, Otis Elmer Monroe, was a house painter from Indianapolis who also painted portraits and landscapes. Otis aspired to live in Paris and worked painting railway cars for the National Railroad of Mexico. The family had Scottish and Irish heritage. In 1903, when Gladys was an infant, the family relocated to Los Angeles County, California, where Otis painted railway cars for the Pacific Electric Railway Company. Della served as a midwife and also provided informal education.
Gladys and her brother Marion Otis Elmer grew up in a turbulent environment due to their father’s struggle with alcoholism, temper issues, health concerns, and frequent relocations. Otis was admitted to Patton State Hospital in San Bernardino County in November 1908 with advanced neurosyphilis and paralysis. He passed away on July 22, 1909, after becoming partly paralyzed and mentally ill. Della sustained the family by working as a domestic servant and renting out rooms. Gladys’s childhood was marked by trauma, bereavement, and financial difficulties.
In 1912, Della wed Lyle Arthur Graves, a railway switchman supervisor, but they divorced in 1914 due to his inability to support the family and excessive drinking. Della subsequently moved to Oregon and married Charles E. Young (or Chitwood) in 1916, but that marriage also concluded because of alcoholism. Gladys lived in various locations, including Venice, Los Angeles, and briefly on a farm in Oregon, where she had fond memories of her stepfather. By 1916 or 1917, Gladys was a socially active teenager who preferred older men.

At 14, Gladys wed John Newton “Jasper” Baker on May 17, 1917, with her mother’s consent and a document stating she was 18. Jasper was a businessman from Kentucky known for his violent temper and heavy drinking. They had two children: Robert Kermit “Jackie” Baker and Berniece Inez Gladys Baker. Gladys filed for divorce in 1921 after experiencing abuse, but Jasper took the children to Kentucky, where his mother aided in raising them. Gladys moved to Kentucky to be near them but left after four months due to fear of Jasper. After that, she had minimal communication with her children. Jackie reportedly passed away in his 20s, and Berniece had little interaction with Gladys for many years.
In 1923, Gladys relocated to Hollywood and worked as a negative film cutter at Consolidated Film Industries, later at Columbia Pictures and RKO. She met Grace McKee (later Goddard), a supervisor who became a close friend. They shared a residence in Silver Lake, reveling in the Roaring Twenties as flappers. Grace assisted Gladys in transforming her appearance and social circle. In 1924, Gladys married Martin Edward Mortensen, a meterman for Southern California Gas Company. That marriage was short-lived; Gladys departed in early 1925 and they divorced in 1928.
In late 1925, Gladys commenced a relationship with her supervisor, Charles Stanley Gifford, who was separated from his spouse. She became pregnant and delivered Norma Jeane Mortenson (later Marilyn Monroe) on June 1, 1926, at Los Angeles County Hospital. Gladys did not allow Gifford to visit and listed Mortensen as the father on the birth certificate. Norma Jeane was baptized as Baker to conceal her illegitimate birth. Gladys struggled with motherhood and placed Norma Jeane with foster parents Albert and Ida Bolender in Hawthorne, California, merely weeks after her birth. Gladys made weekend visits but could not offer consistent care.

Updates
As of January 2026, people continue to discover elements of Gladys Pearl Baker’s life through Marilyn Monroe’s enduring cultural impact:
- The 2022 Netflix movie Blonde, directed by Andrew Dominik and featuring Ana de Armas as Marilyn and Julianne Nicholson as Gladys, revived interest in Gladys’s life, her mental health struggles, and her connection with her daughter. The film portrays Gladys’s time in institutions and her emotional disconnection from Norma Jeane, who eventually became Marilyn.
- Books, biographies, and documentaries (including The Mystery of Marilyn Monroe: The Unheard Tapes on Netflix, 2022) persist in exploring Gladys’s influence on Marilyn’s upbringing and the impact of her mental health issues on their lives.
- No significant new documents, letters, or family revelations regarding Gladys have emerged in 2024 or 2025. Her narrative remains vital in Monroe studies, particularly concerning women’s mental health care in the early 1900s, single motherhood, and working in Hollywood during the studio period.
- Marilyn Monroe’s estate and archives occasionally present or mention materials about Gladys, yet there have been no substantial updates altering the existing knowledge of her life and experiences in institutions.
Cause of Death
Gladys Pearl Baker passed away on March 11, 1984, at a senior care facility in Gainesville, Florida, at age 81. The official cause of death was heart failure. She endured chronic mental illness, diagnosed as paranoid schizophrenia, for many years and spent a significant portion of her adult life in psychiatric hospitals, including Norwalk State Hospital, Agnews State Hospital, and Rockhaven Sanitarium. After her discharge from care in 1967, she resided with her daughter Berniece in Florida and later in a retirement home. Gladys battled depression, agitation, and the repercussions of prolonged mental health issues.
Institutional care, yet cardiac failure was the primary reason for passing. No autopsy specifics or other elements were broadly reported. She rests in a Gainesville burial ground. Her demise garnered minimal public interest in contrast to her daughter Marilyn Monroe’s famous departure in 1962.
Partner
Gladys Pearl Monroe experienced three unions:
- Jasper Newton “Jap” Baker (wed May 17, 1917 – divorced 1921): Gladys wed him at the age of 14, with her mother’s approval and a document stating she was 18. Together, they had two offspring, Robert Kermit “Jackie” Baker and Berniece Inez Gladys Baker. Jasper was abusive and indulged heavily in alcohol, prompting Gladys to seek divorce after violent episodes. Jasper took the kids to Kentucky, where his mother assisted in raising them. Gladys relocated to Kentucky briefly but departed after four months due to her fear of Jasper. Following this, she had minimal connection with her offspring.
- Martin Edward Mortensen (wed October 11, 1924 – divorced August 15, 1928): He was employed as a meterman for Southern California Gas Company. The matrimony was brief and discontented; Gladys departed from him in early 1925. Mortensen petitioned for divorce, asserting she abandoned him. He is officially recognized as Norma Jeane’s father on her birth certificate because Gladys was still wed to him at the time of Marilyn’s birth in 1926.
- John Stewart Eley (wed 1949 – expired April 23, 1952): He worked as an electrician. Gladys claimed Eley was abusive and consumed too much alcohol. She filed for divorce in February 1952. Eley passed shortly thereafter, and another woman, who alleged she had married him earlier, inherited his estate.
Gladys also engaged in relationships with other men, including a notable affair with Charles Stanley Gifford, her supervisor at RKO, who fathered Norma Jeane (Marilyn Monroe).
Offspring
Gladys Pearl Baker was the parent of three children:
- Robert Jasper “Kermit” Baker (born circa 1918–1920; deceased in his 20s): He was Gladys’s child with her first spouse, Jasper Baker. Kermit suffered severe injuries as a child when he fell from the family vehicle, which left him disabled. Following Gladys and Jasper’s divorce, Jasper transported Kermit and his sister Berniece to Kentucky. Kermit died young, and he never reconnected with Gladys.
- Berniece Inez Gladys Baker (born 1919–1920; deceased in the 1990s): She was the offspring of Jasper Baker. Berniece was also taken to Kentucky by her father and had limited contact with Gladys as a child. Later, she resided in Florida and assisted her mother in her later years. Berniece penned her account regarding her half-sister Marilyn Monroe in the book My Sister Marilyn (1994, co-authored with Mona Rae Miracle).
- Norma Jeane Mortenson (June 1, 1926 – August 5, 1962), later recognized as Marilyn Monroe, was the daughter of Charles Stanley Gifford (confirmed by 2022 DNA analysis). Gladys was unable to care for Norma Jeane and placed her in foster care just weeks after her birth. Norma Jeane lived with foster families, the Bolenders, and subsequently in orphanages. Gladys had sporadic contact with her and spent much of Norma Jeane’s upbringing in institutions. Marilyn Monroe later provided financial support to Gladys through a trust fund.
Films
Gladys Pearl Baker never featured in any films. She worked behind the scenes in Hollywood as a negative film cutter (editor) at Consolidated Film Industries, Columbia Pictures, and RKO Pictures during the 1920s and early 1930s. Her role involved physically cutting and splicing film negatives, eliminating unwanted scenes and assembling reels for final prints during the silent movie period and early talkies. This was specialized, technical labor in the expanding film industry. Gladys’s role in film labs introduced young Norma Jeane to the cinematic world, though she was rarely on set. Marilyn Monroe eventually became one of Hollywood’s most prominent stars, but Gladys never acted or appeared on screen. Her life and contributions are depicted in biographical films and miniseries regarding Marilyn Monroe:
- The Secret Life of Marilyn Monroe (2015 TV miniseries) — Gladys portrayed by Susan Sarandon and Eva Amurri (younger version).
- Blonde (2022 Netflix film) — Gladys, portrayed by Julianne Nicholson.
- Other Monroe biopics and documentaries (e.g., Marilyn: The Untold Story, 1980) occasionally mention Gladys but do not concentrate on her film contributions.
Gladys’s behind-the-scenes work in early Hollywood is a minor aspect of her daughter’s narrative, and there is no surviving footage or credits displaying her onscreen.
