Ten days prior, John and Jackie Kennedy lost their newborn son Patrick to infant respiratory distress syndrome 39 hours after his birth. Having already suffered a miscarriage in 1954, and a stillbirth the following year, Patrick's death was an especially difficult loss for the First Couple. An assassin's bullet would claim the life of President Kennedy just three months later.
