Another interesting fact:

Franklin Roosevelt's famous inaugural line, 'The only thing we have to fear is fear itself," was composed by Louis Howe.

(Okay, I know it's not surprising that FDR didn't write his famous lines. But I always wonder how it would change our perceptions if we had credits at the end of presidential speeches. Imagine: this speech was written by X, edited by Y, brought to you by . . . )
