Sixteen days after that, on June 11, 1979, John Wayne passed away at UCLA Medical Center. In his final months, he had enrolled in an experimental cancer vaccine study, telling doctors, ”If this is helpful, I’m going to help you afterward.”
His family would go on to establish the John Wayne Cancer Institute, carrying forward his legacy of courage and hope.

According to a LA Times piece, for years his grave’s location remained a mystery. Guards locked fans out of his funeral service, and his farewell ceremony remained a private affair. His grave was left unmarked for two decades.
