JFK’s rise to power. With illuminating interviews from family members, including sister Jean Kennedy Smith, historian Robert Dallek, and author Robert Caro, this episode offers new insight into Kennedy’s early years. John Fitzgerald Kennedy is one of nine children born to one of the wealthiest men in America. Unlike his robust siblings, he is haunted by a mysterious illness. Finally diagnosed with Addison’s disease, he will spend his life in and out of hospitals and in constant pain. Jack Kennedy first bursts onto the national stage as a war hero through his courageous rescue of his PT-109 crewmen. When his older brother, Joe Jr., is killed in the line of duty in 1944, the family’s political hopes shift to Jack. Despite the odds, he wins his Grandfather Fitzgerald’s old Massachusetts congressional seat. With his congressional win, Kennedy rises in power and influence, unseating Senator Henry Cabot Lodge in a surprising victory.
