Grace Kelly was an American actress who transitioned to become a princess when she married Prince Rainier III of Monaco in 1956. Born in Philadelphia in 1929, Kelly came from a wealthy family and initially pursued a career in acting in New York City. She garnered critical acclaim for her roles in several films, including High Noon and Rear Window, before winning an Academy Award for her performance in The Country Girl in 1954. Kelly retired from acting after she married Prince Rainier, and instead focused on her duties as princess and philanthropist. She had three children with Rainier and was beloved by the people of Monaco for her elegance and grace. Tragically, Kelly died at the age of 52 in a car accident in 1982, leaving behind a legacy as both a Hollywood icon and a beloved member of the royal family.
