Yesterday's It's Ac Fact

Yargh. I forgot to post an It's Ac fact of the day yesterday! So here it is:

The author Nathaniel Hawthorne, known for such works as The Scarlet Letter, The House of The Seven Gables, and The Blythesdale Romance was a friend to president Franklin Pierce. Now, if any of you can say which number president Pierce was and what years he was in office, without using Wikipedia, I will present you an invisible cookie! Oh, and you should very definitely come to It's Academic on Tuesday.

(Ozymandias is not allowed to answer, btw.)
