Franklin, Printer (Like the Cover of an Old Book Its Contents torn Out and Stript of its Lettering and Gilding) Lies Here, Food for Worms. But the Work shall not be Lost: For it will (as he Believ’d) Appear once More In a New and More Elegant Edition Revised and Corrected By the Author.” It was not used however, and most will never understand how influential his contributions were: Founding Libraries, universities, the post office, creating bifocals, discovering electricity, creating the Franklin stove and yet never completed school.
