It was on this day in 1982 that American actress Grace Kelly passed away following a major auto accident the day before. Kelly, who had married Prince Rainier III in April 1956 and became Princess of Monaco, was driving a 1971 Rover P6 3500 when she suffered a stroke. This led her to lose control of her car, in which her 18-year-old daughter Stephanie was a passenger, and the vehicle went over a steep 120 foot embankment. Paramedics arrived to find Kelly alive but unconscious and in critical condition. They brought her to Monaco Hospital where they discovered the not only suffered brain injuries from the stroke, but thorax and femur fractures as well. Doctors were unable to resuscitate her and she was placed on life support. Her daughter was found to have a fracture of her seventh cervical vertebra. The following day, today in 1982, Rainier had Kelly removed from life support and she passed away at 10:55 p.m. at the age of 52. Her funeral in Monaco was attended by many notable people, including Cary Grant, Diana, Princess of Wales and Nancy Reagan.
