Years before he captained the torpedo boat PT-109, ran for office or set the United States on a path to put a man on the moon, President John F. Kennedy was a troublesome teen whose high jinks nearly got him kicked out of his prestigious boarding school.

The scion of a wealthy Boston family, Kennedy spent his midteens at Connecticut¡¯s elite Choate Rosemary Hall, where he excelled at history and literature ¡ª but infuriated the school¡¯s headmaster by organizing pranks as a member of an unofficial school club known as The Muckers.

Those details of the early life of the 35th president, whose term was cut short by an assassin¡¯s bullet in Dallas in 1963, emerge in a new exhibit at Boston¡¯s John F. Kennedy Presidential Library and Museum, timed to commemorate the 100th anniversary of his birth on May 29, 1917.
