Don't Quit: Who is the Author?

In Reference to the Poem: DON’T QUIT

I am finding amusement at the various people whom claim to have known or are the creator of the don’t quit poem. I can assure you that the person who did this marvelous writing is long gone, it was written in the 50’s, and it was inspired by the depression. I know this because I have an original signed copy from my grand father.

Please keep the poem around, it is what he would have wanted.
