When I learned about this coincidence, I realized I have little idea about the order of historical events that are older than I am.
I thought the U.S. Civil War, for example, was back in the 1700s. It actually happened from 1861 to 1865 (just as Canada was creating itself).
I also thought that Bach and Beethoven were contemporaries. But J.S. Bach lived from 1685 to 1750 whereas Beethoven wasn’t born until 1770. So they probably never met.
