John F. Kennedy biography

Although he was obviously brilliant -- evidenced by the extraordinary thoughtfulness and nuance of his work on the rare occasions when he applied himself -- Kennedy remained at best a mediocre student, preferring sports, girls and practical jokes to coursework.

His father wrote to him by way of encouragement, "If I didn't really feel you had the goods I would be most charitable in my attitude toward your failings ... I am not expecting too much,

and I will not be disappointed if you don't turn out to be a real genius, but I think you can be a really worthwhile citizen with good judgment and understanding." Kennedy was in fact very bookish in high school, reading ceaselessly but not the books his teachers assigned. He was also chronically ill during his childhood and adolescence; he suffered from severe colds, the flu, scarlet fever and even more severe, undiagnosed diseases that forced him to miss months of school at a time and occasionally brought him to the brink of death.

After graduating from Choate and spending one semester at Princeton, Kennedy transferred to Harvard University in 1936. There, he repeated his by then well-established academic pattern, excelling occasionally in the classes he enjoyed, but proving only an average student due to the omnipresent diversions of sports and women. Handsome, charming and blessed with a radiant smile, Kennedy was incredibly popular with his Harvard classmates. His friend Lem Billings recalled, "Jack was more fun than anyone I've ever known, and I think most people who knew him felt the same way about him." Kennedy was also an incorrigible womanizer. He wrote to Billings during his sophomore year, "I can now get tail as often and as free as I want which is a step in the right direction."

Nevertheless, as an upperclassman, Kennedy finally grew serious about his studies and began to realize his potential. His father had been appointed Ambassador to Great Britain, and on an extended visit in 1939, Kennedy decided to research and write a senior thesis on why Britain was so unprepared to fight Germany in World War II. An incisive analysis of Britain's failures to meet the Nazi challenge, the paper was so well-received that upon Kennedy's graduation in 1940 it was published as book, Why England Slept, selling more than 80,000 copies. Kennedy's father sent him a cablegram in the aftermath of the book's publication: "Two things I always knew about you one that you are smart two that you are a swell guy love dad."

Shortly after graduating from Harvard, Kennedy joined the U.S. Navy and was assigned to command a patrol torpedo boat in the South Pacific. On August 2, 1943 his boat, PT-109, was rammed by a Japanese warship and split in two. Two sailors died and Kennedy badly injured his back. Hauling another wounded sailor by the strap of his life vest, Kennedy led the survivors to a nearby island, where they were rescued six days later. The incident earned him the Navy and Marine Corps Medal for "extremely heroic conduct" and a Purple Heart for the injuries he suffered.
