Sense Sonnet - Pumper

 Underwood Typewriter

Franz Xaver Wagner was the one

Inventing me, very smart bloke.

Users could see their work as done,

Because I provided front stroke.

Franz bundled me up, took me to

Entrepreneur, John Underwood,

So impressed at what I could do,

Thought me a profitable good.

So started company to sell

In early 1900's, me,

First modern type. I sold so well

That rich men, John and Franz did be.

For decades I did garner fame,

Underwood Typewriter, my name.
