Norma Jeane Mortenson, aka Marilyn Monroe, was one of (if not THE) most famous sex symbols of the 20th century. She was emblematic for the Sexual Revolution, cover girl of the very first Playboy issue and a top-billed Hollywood actress. But one of her most famous acts was singing Happy Birthday Mr. President for John F. Kennedy, on 5/19/1962. There are even rumors of an affair between the two of them.
She died only a few weeks later, on 8/4/1962. That was exactly 11 weeks after that song.
