Who are these people?

If you can figure out the instructions just by looking at the grid, go ahead and solve the puzzle.
(Think about “Denzel Orwell.”) Otherwise, see the directions at the bottom of the page.

I don’t know who these people are. But if you think of the last name of a famous person with the first name shown, and the first name of a famous person with the last name shown, the result will be the name of a U. S. president . . . if you think of the correct famous people. (In our solution, there are no duplicate first or last names, but one first name is the nickname of another.)

Example:
Blind Lemon
Edison
Blind Lemon Jefferson yields the last name Jefferson,
while Thomas Edison yields the first name Thomas,
giving us the name Jefferson, Thomas.
