For six decades, Agnes Moorehead built one of the most respected careers in American entertainment—radio dramas, Broadway, Hollywood films, and a television role that made her a household name. Yet the details of her private life, and the circumstances surrounding her death in 1974, have been the subject of enduring debate and speculation. Moorehead was born on December 6, 1900, in Clinton, Massachusetts, the daughter of a Presbyterian minister. Raised in a strict, disciplined household, she studied biology at Muskingham College and later drama and public speaking at the University of Wisconsin.
She taught English for a time before moving to New York in 1927 to train at the American Academy of Dramatic Arts. She quickly found steady work in radio, an industry booming in the 1930s. Her clear voice and professional discipline made her one of the busiest actresses on the air. She met Orson Welles in that world, and when he founded the Mercury Theatre in 1937, Moorehead became a core member of his company.
When Welles took his troupe to Hollywood to make his first film, Moorehead was among those he brought. In 1941, at age 40, she made her film debut in Citizen Kane, playing the mother of Charles Foster Kane. Her brief, restrained scene, in which she signs away her young son, remains one of the most praised moments in the film. Welles cast her again in The Magnificent Ambersons (1942) as Aunt Fanny, a woman whose repressed feelings finally break loose in a devastating scene.
That performance brought Moorehead the first of four Academy Award nominations. She would be nominated again for Mrs. Parkington (1944), Johnny Belinda (1948), and Hush… Hush, Sweet Charlotte (1964). She never won.
Moorehead also originated the role of the terrified invalid in Lucille Fletcher’s radio thriller Sorry, Wrong Number in 1943, performing it eight times on the air. It became one of the most celebrated pieces of dramatic radio ever broadcast. Her personal life was quieter and more difficult. She married actor John Griffith Lee in 1930; they divorced in 1952.
During the marriage, she took in a young boy named Shawn, whom she raised as her son and described as family. In 1953, she married actor Robert Gist, nearly 17 years her junior. They divorced in 1958. In the mid-1950s, Moorehead worked on The Conqueror, a historical epic produced by Howard Hughes and starring John Wayne as Genghis Khan.
The production shot for months in the desert of southwestern Utah, near the town of St. George—a region that had received radioactive fallout from atmospheric nuclear tests at the Nevada Test Site. The tests were not secret, and the public was repeatedly assured they posed no danger. No health warnings were issued to the film company or the hundreds of local residents hired as extras.
Moorehead continued working steadily for years after. She toured the country with her one-woman show, and in 1964 she joined the cast of the new sitcom Bewitched as Endora, the imperious witch mother of Samantha. The series ran for eight seasons and made her one of the most recognized faces on American television. In 1967, away from Bewitched, she won an Emmy for a dramatic guest performance on The Wild Wild West.
It was her only major competitive acting award after four Oscar losses. By the early 1970s, Moorehead’s health was failing. Later biographical accounts identify the illness as uterine cancer, but the hospital that cared for her would not disclose the cause of death, saying she had asked that the information remain private. She continued working as long as she could, including a run in the Broadway musical Gigi that ended in January 1974.
She was admitted to Methodist Hospital in Rochester, Minnesota, in April 1974 and died there on April 30, at age 73. She was buried in Dayton, Ohio, beside her parents and her sister Peggy. Her life became the subject of renewed scrutiny because of The Conqueror. In 1980, People magazine reported that of the 220 cast and crew members who had worked on location in Utah, 91 had developed some form of cancer and 46 had died of it.
Among the dead were John Wayne, Susan Hayward, Pedro Armendáriz, director Dick Powell, and Agnes Moorehead. Government records confirm that radioactive fallout from Nevada Test Site explosions did drift over southwestern Utah, and that residents of the region later showed elevated rates of certain cancers. In 1990, Congress passed the Radiation Exposure Compensation Act to provide payments to some affected downwind residents. However, no scientific study has ever established a direct causal link between the Utah shoot and the cancers of specific members of the film company.
Some researchers have noted that the group was small and included many heavy smokers, making statistical conclusions unreliable. Others have argued the pattern of illness suggests more than chance. The medical cause of Moorehead’s own cancer has not been proven. Several later accounts said Moorehead suspected the location work had contributed to her illness.
That belief was attributed to her by people who knew her, but it remains a reported belief, not a medical finding. Near the end of her life, Moorehead instructed that her private diaries be destroyed after her death. According to later accounts, that request was carried out. She chose to take her private thoughts with her.
She left behind an extraordinary body of work: hundreds of radio performances, dozens of films, eight seasons of television, recordings, and interviews. Her diaries were not among them.
