On vacation, my friend (and frequent Muttroxia commenter) and I were chatting and Harrison Ford came up. He noticed that both his names were the surnames of Presidents (Benjamin Harrison & Gerald Ford). We tried to come up with any other famous people who were the same. A few hours later he got one. I couldn’t get any.
The puzzle is to find any reasonably famous person whose first and last names are the surnames of American Presidents. It must be the actual form of the name (Adams or Jefferson, not Adam or Jeff).
