Patrick Bouvier Kennedy, American son of John F. Kennedy (b. 1963)
Patrick Bouvier Kennedy (August 7–9, 1963) was the infant child of President John F. Kennedy and First Lady Jacqueline Kennedy and the younger brother of Caroline, John Jr., and Arabella.

Born prematurely, Kennedy lived just over 39 hours before dying from complications of hyaline membrane disease (HMD), after desperate attempts to save him failed. His infant death left the First Family and nation in mourning, however, also brought HMD, now known as infantile respiratory distress syndrome, into the public consciousness, inspiring further research. Three months later, his death would be eclipsed by his father's assassination.
