On November 19, 1863, President Abraham Lincoln gave his famous Gettysburg Address, a speech which is not only significant because of its historical context at the turning point in one of the most important wars in the history of the world - and the single most noteworthy war in the history of the United States - but which is also a masterpiece of language.
Lincoln was sandwiched between several other speeches which were given that day by other politicians. These other speakers each spoke for approximately an hour, making a long day of it. Lincoln, by contrast, probably took about two minutes for his oration!
Editorializing about the event, The Chicago Sun wrote: "The cheek of every American must tingle with shame, as he reads the silly, flat, and dishwatery utterances of the man who has to be pointed out to intelligent foreigners as the President of the United States."
Today, textbooks around the world cite Lincoln's work as a paradigmatic example of the English language!
