Who Is James Lamarr Markey?
James Lamarr Markey is best known as the adopted son of actress Hedy Lamarr. He was born in January 1939 in Los Angeles during Hollywood’s golden era. James Lamarr Markey later became a central figure in one of the era’s more unusual family disputes. Unlike his mother, he avoided the entertainment industry entirely throughout his adult life.
James Lamarr Markey’s Early Life
James Lamarr Markey was born on January 9, 1939, in Los Angeles, California. His birth came during a period when Hedy Lamarr was becoming one of MGM’s most recognized stars. She had recently arrived in Hollywood after building early fame in Europe. James Lamarr Markey entered a household already shaped by fame and public attention.
Hedy Lamarr’s Rising Career
Hedy Lamarr made her American film debut in Algiers in 1938, just one year before James arrived. This role quickly established her as a major Hollywood presence. She went on to appear in several successful films during the following decade. James Lamarr Markey grew up watching his mother’s career expand rapidly during his earliest years.
James Lamarr Markey’s First Adoption
Gene Markey, a screenwriter married to Hedy Lamarr at the time, adopted James shortly after his birth. This adoption gave him the Markey surname that later became part of his identity. Hedy spoke publicly about preparing a nursery and welcoming James into the family. However, her marriage to Gene Markey ended in 1941, only two years later.
The Custody Battle After the Divorce
Hedy Lamarr fought to retain custody of James following her divorce from Gene Markey. She succeeded in keeping him and brought him into her next marriage. This decision showed her early determination to raise him as her own son. It also set the stage for the complicated family structure that followed.
James Lamarr Markey’s Second Adoption
Hedy married British actor John Loder in 1943, her third husband. Loder adopted James shortly after the wedding, adding another layer to his legal identity. This meant James had been adopted twice before reaching his fifth birthday. His surname changed again, reflecting the shifting structure of his family.
The Birth Certificate Discovery
Years later, James found a copy of his birth certificate listing John Loder as his biological father. This document suggested he may not have been adopted at all. At the time of his birth, however, Hedy was still married to Gene Markey. This discovery created confusion that would follow James for the rest of his life.
The DNA Test Results
A DNA test eventually confirmed that James was not biologically related to Hedy Lamarr or John Loder. This result contradicted the birth certificate and settled years of uncertainty. It confirmed Hedy’s lifelong claim that James was adopted rather than her biological son. Despite this, the emotional bond and legal history remained complicated.
James Lamarr Markey’s Half-Siblings
Hedy Lamarr had two biological children during her marriage to John Loder. Denise Loder was born in 1945, followed by Anthony Loder in 1947. Both siblings later said they had no memories of James from childhood. This absence reflected how early he had been separated from the family.

Education and Boarding School Struggles
James Lamarr Markey attended Chadwick Military School, a school known for serving wealthy Southern California families. He faced serious trouble there around age eight and was ultimately expelled. The specific reasons were never publicly disclosed. This event marked the beginning of his separation from Hedy Lamarr’s household.
Life After Leaving Military School
Following his expulsion, James lived with his teacher and her husband so he could continue his education. Hedy initially resisted this arrangement before eventually agreeing to it. She set up a trust fund to support his care and schooling. This arrangement effectively removed him from her daily life at a young age.
The Estrangement From Hedy Lamarr
James and Hedy became estranged when he was around eleven or twelve years old. He later recalled writing letters to her that were returned unopened. According to James, Hedy told him plainly that he was no longer her son. This estrangement reportedly lasted for close to fifty years.
Hedy Lamarr’s Explanation for the Rift
Hedy rarely discussed James publicly during her later years. According to his half-sister Denise, something happened that deeply hurt Hedy, though the details were never shared. When asked why she avoided the topic, Hedy simply said he had hurt her. This brief explanation left much of the story unresolved.
Hedy Lamarr’s Death and the Will
Hedy Lamarr died in January 2000. Her will specifically excluded James, listing him under several names, including James Markey and James Lamarr Loder. This formal exclusion confirmed that their relationship had never been repaired. James was not invited to attend the funeral by choice, despite an offer from his siblings.
James Lamarr Markey’s Estate Dispute
James challenged Hedy’s will in a Florida court, seeking a share of her $3.3 million estate. His siblings initially offered him $20,000, which he rejected. He eventually accepted a settlement of $50,000 from Anthony and Denise. This dispute marked one of the only public appearances James made in adulthood.
