"King" doesn't work for "Martin Luther King" and "Presley" doesn't work for "Elvis Presley". Besides that, cool quiz! I'm surprised they didn't include Malcolm X.
I think F. Scott Fitzgerald and Aaron Copland should be in this list. I too couldn't understand why Lewis and Clark didn't make the list as individuals.
Jolly fun. I wish that one could type in "Lewis" or "Clark" and leave it at that. I tried Hoover, Chavez, Sequoia, Chief Joseph, and Ali, and was surprised that they were not on there. One could argue for hours about the list. fun quiz!
Check out my Women Composers quiz, too!
My list would be pretty different than this one.

Very good quiz anyway! Makes you think.
