Gelett Burgess, a draftsman and illustrator by trade, is probably best known for the poetry he left behind. Though even this is somewhat lost to history, perhaps because his most famous books are volumes of nonsense poetry. Take, for example, this, probably his most famous single poem:

I never saw a Purple Cow,
I never hope to see one,
But I can tell you, anyhow,
I'd rather see than be one!
