Who delivered the famous Gettysburg Address in 1863?

After delivering the speech which only lasted a couple of minutes he sat down and said to his secretary "That plough won't scour." A country way of saying it will be forgotten by tomorrow. Definitely one of the greatest speeches ever delivered by a politician.

Cas, I agree, to a very minute point. I would venture to say, that it was definitely one of the greatest speeches ever delivered in history, politician or no politician.
