According to longtime friend Carlotta Glackin, who confirmed the news to The Hollywood Reporter, Bower passed away on April 30, 2026, at a retirement residence in the Eagle Rock area of Los Angeles.
Born on September 30, 1932, in Baden-Baden, Germany, Bower enjoyed a successful acting career spanning nearly four decades. She made her television debut in 1958 and became a familiar face on American television throughout the 1960s, 1970s, and 1980s.

Her film career included a memorable role in the 1980 slasher classic Prom Night, where she starred alongside Leslie Nielsen and portrayed the mother of Jamie Lee Curtis’ character.
After an uncredited appearance in Marlon Brando’s 1962 film Mutiny on the Bounty, Bower established herself as one of Hollywood’s most reliable character actresses. Over the years, she appeared in numerous acclaimed television series, including Mannix, Columbo, Mission: Impossible, Kojak, Perry Mason, The Big Valley, Bonanza, Murder, She Wrote, and the acclaimed 1983 miniseries The Thorn Birds, where she portrayed wealthy socialite Sarah MacQueen.
