The poem tells you to find the names that match the name and pseudonym of the creator of Wonderland in the fourth column of the memorial for WWI on the wall of Lobby 10. In that column, you can find the names LEWIS PRESCOTT, whose first name is the name as the pseudonym LEWIS CAROLL, and CHARLES SMITH, matching the real name CHARLES DODGSON. Midway between the two is GEORGE ROPER JR, the answer to this puzzle.
