A voice from the past

This story is really cool.

For nearly 150 years, Abraham Lincoln's pocket watch has been rumored to carry a secret message, supposedly written by an Irish immigrant and watchmaker named Jonathan Dillon.
...
This morning, in a small conference room on the first floor of Smithsonian's National Museum of American History, officials decided to find out. Expert watchmaker George Thomas used a series of delicate instruments -- tweezers, tiny pliers -- to pull apart Lincoln's timepiece. He put on a visor with a magnifying lens and talked as he worked. Some of the pins were nearly stuck, he explained. The hands of the watch were original with a case made in America and the workings from Liverpool. The Illinois rail-splitter had splurged: The watch, Thomas said, would be the equivalent to a timepiece costing "$5,000 or more" today.

And then he pried off the watch's face, pulled off the hands, and turned it over to see the brass underside of the movement.

The audience, watching on a monitor, gasped.

Read the rest. It's a fascinating look back at an urban legend, human memory and a moment of history.
