Q: Name a famous American from the past who has seven letters in his or her last name. Take the last two letters, plus the first four letters, in that order, and you'll name that person's profession. Who is it?Given that this person's Wikipedia page lists 10 professions, can you be sure you'll find this person's intended profession in a sample list of occupations? Remember, your search needs to be exhaustive if you want to be sure not to miss it.
Edit: My hint was "be exhaustive" (i.e. "thorough")
