The 4 panes, transparent glass lamp was good looking and bright in the night to illuminate roads.

In , the American colonies stood on the point of warfare with France, which is one of the great Benjamin Franklin inventions. France, especially, took to the portly American England's honeymoon with Franklin ended after he sided with the Americans during the Revolutionary War, of course.

When Franklin came to France as the United States' first ambassador, Parisians snapped up all manner of Franklin kitsch.

His image was plastered on snuff boxes and medallions, and engravings of the man adorned the walls of any stylish French apartment.

A man of letters himself, Franklin dove into the task with a firm resolve to speed up communication between the colonies. He started by touring America's major postal centers, studying ways to standardize streamline mail delivery.

Along the way, Franklin charted the distances between postal stations by attaching a geared device to the rear wheel of his horse carriage.

It wasn't the world's first odometer ; rudimentary mileage recorders had been appearing as far back as ancient Roman times. Franklin's design also wasn't the last odometer; inventors in Nova Scotia and the Midwest would independently conceive of similar devices in decades to come.
