Who first said "We are the music makers..."?

Search: "we are the music makers"

Why: I was just watching "250 Introductions of 185 People, Groups, & Things." Near the end, Willy Wonka says it, but I think I have also heard it sampled in some song.

Answer: Arthur William Edward O'Shaughnessy! It's the opening of "Ode" from his 1874 book Music and Moonlight:

We are the music makers,
And we are the dreamers of dreams,
Wandering by lone sea-breakers,
And sitting by desolate streams;—
World-losers and world-forsakers,
On whom the pale moon gleams:
Yet we are the movers and shakers
Of the world for ever, it seems.
