Every Death Depicted in Mad Men

Deaths are more than tragedies. In Mad Men, deaths shape the life trajectories of the characters.
Here are a few I missed:

In Mad Men Season 3, Episode 12 "The Grown-Ups", John F. Kennedy's death is announced, though he's not a fictional character of the series. The same for Lee Harvey Oswald.
