In this photo montage, PEB denotes, with slight humor, the historic rarity of any American President fathering a son who also attains the honor of being our Commander in Chief. Only once before have we in America experienced such a phenomena: John Adams, serving from 1797 through 1801, was the father of John Quincy Adams, who served during 1825 through 1829. PEB apologizes for the spelling error in the word 'constitutional'!
