Jefferson's Letter

Writing about the news because I'm not ready to talk about anything else.

A grad student finding a letter of recommendation from Jefferson is not so interesting in itself, despite the library official's attempts to make it sound like a testament to Jefferson's humility which belied an unfamiliarity with the tone of such letters surprising from a university official. The interesting line in the article was this one...

"Historians had been aware of the existence of the letter, thanks to Jefferson's use of a portable copying press, one of his many inventions."

It is of course unclear what they mean - I assume there a copy of this letter already in the possession of the authorities, and this is the original?

But I was curious about the invention - it turns out that they're talking about the polygraph machine:

Cool, huh?
