Lots of things, actually.
While we were watching Jeopardy! tonight - it may have been from last week, since i haven't been keeping up & prefer to watch them in order - 0ne of the questions was just like this.
Clues from Colors, LabelsIn the program, we could have had a clue from the category. Since i don't remember the category, i've given you two different ones.
None of the contestants got it. i think that, as Boom said, we in the USA look at this date and think, "Something leading up to the Revolution - should know it."
The answer was about German poet Goethe. * Maybe not a big part of his life, but perhaps something that would have suggested itself given the date & category if minds were not clouded with the obvious.
*Hmmm, the Wikipedia editors have been at it again - the answer's not as obvious as it was. Ok, here is the quote:
"A literary celebrity by the age of 25, Goethe was ennobled by the Duke of Saxe-Weimar, Carl August in 1782 after first taking up residence there in November of 1775 following the success of his first novel, The Sorrows of Young Werther."
My quote is from my original link, to the Weimar section of the main article. Maybe i got the wrong section; the event is easier to see in the Early Years in Weimar section, where the date is first in the paragraph.
