On this date in 1962 Marilyn Monroe sang Happy Birthday to John F. Kennedy at a birthday salute held at Madison Square Garden in New York. Monroe’s breathless rendition was played frequently on the news and continues to be a favorite film clip whenever she or President Kennedy are profiled. It has been reported that JFK and Monroe had an ongoing affair. By 1962 Monroe had become more insistent in her pursuit of the President with whom she was reportedly in love. At that point Kennedy broke off the relationship and Monroe switched her affections to John’s younger brother Robert. It is believed that Robert visited Monroe on the day she died in August of that year.
