John Fitzgerald Kennedy never made it through his one term as president of the United States but his brief tenure and his life leading up to his presidency are well-chronicled. However, the Brookline native’s links to the Berkshires in the far west of his state are not as well known. That has been addressed in a recently published posthumous memoir, “The Human Touch: My Friendship And Work With President John F. Kennedy” by John G. W. Mahanna.
