In short: Mercedes McCambridge was a powerhouse of radio and film, hailed by Orson Welles as the world's greatest radio actress. From winning an Oscar for her screen debut to providing the terrifying, gravelly voice of the demon in The Exorcist, her life was defined by intense professional commitment and profound personal struggle.

Born in 1916, McCambridge began her career in radio in 1938, quickly becoming a fixture of the medium. Her film career flourished with her 1949 debut in All the King's Men, which earned her an Academy Award for Best Supporting Actress. She remained a formidable presence on screen, appearing in classics like Giant and Suddenly, Last Summer, and reuniting with Orson Welles for Touch of Evil. Her most iconic vocal performance came in 1973, when she provided the voice for the demon Pazuzu in The Exorcist. To achieve the character's disturbing, harsh tone, she chain-smoked, drank whiskey, and swallowed raw eggs, even requesting to be bound to a chair during recording sessions to simulate the entity's struggle.

Beyond her artistic achievements, McCambridge was a pioneer in public discourse regarding alcoholism. She battled the disease for years and, while she admired Alcoholics Anonymous, she achieved sobriety independently to maintain her privacy. In 1974, Dick Van Dyke credited her with breaking the ice for other celebrities by speaking openly about her addiction. From 1975 to 1982, she served as president and CEO of the Livengrin Foundation, a residential treatment center in Pennsylvania, using her celebrity to destigmatize addiction and promote recovery.

Her later years were marked by a devastating family tragedy. In 1987, her son, John Markle, was discovered to have forged her signature to open a secret investment account, where he charged trading losses to her name while keeping profits for himself. After being fired from his firm, Markle killed his wife and two daughters before taking his own life in November 1987. He left a bitter note blaming his mother for the financial dispute and their fractured relationship. McCambridge, who had ironically starred in a 1986 production of the play 'night, Mother—a story about a child planning suicide—died in 2004 at age 87.
