On June 11, 1979, John Wayne, an iconic American film actor famous for starring in countless westerns, dies at age 72 after battling cancer for more than a decade.

The actor was born Marion Morrison on May 26, 1907, in Winterset, Iowa, and moved as a child to Glendale, California. A football star at Glendale High School, he attended the University of Southern California on a scholarship but dropped out after two years. After finding work as a movie studio laborer, Wayne befriended director John Ford, then a rising talent. His first acting jobs were bit parts in which he was credited as Duke Morrison, a childhood nickname derived from the name of his beloved pet dog.

Wayne’s first starring role came in 1930 with The Big Trail, a film directed by Raoul Walsh. It was during this time that Marion Morrison became “John Wayne,” when director Walsh didn’t think Marion was a good name for an actor playing a tough western hero. Despite the lead actor’s new name, however, the movie flopped. Throughout the 1930s, Wayne made dozens of mediocre westerns. In them, he played various rough-and-tumble characters and occasionally appeared as “Singing Sandy,” a musical cowpoke a la Roy Rogers.

In 1939, Wayne finally had his breakthrough when his old friend John Ford cast him as Ringo Kid in the Oscar-winning Stagecoach. Wayne went on to play larger-than-life heroes in dozens of movies and came to symbolize a type of rugged, strong, straight-shooting American man. John Ford directed Wayne in some of his best-known films, including Fort Apache (1948), She Wore a Yellow Ribbon (1949), Rio Grande (1950), The Quiet Man (1952) and The Man Who Shot Liberty Valance (1962).

Off-screen, Wayne came to be known for his conservative political views. He produced, directed and starred in The Alamo (1960) and The Green Berets (1968), both of which reflected his patriotic, conservative leanings. In 1969, he won an Oscar for his role as a drunken, one-eyed federal marshal named Rooster Cogburn in True Grit. Wayne’s last film was The Shootist (1976), in which he played a legendary gunslinger dying of cancer. The role had particular meaning, as the actor was fighting the disease in real life.

During four decades of acting, Wayne, with his trademark drawl and good looks, appeared in over 250 films. He was married three times and had seven children.
