Interesting. I&#x27;ve always heard that quote ascribed to Niels Bohr.<p>Perhaps he was just the first Dane to use it. I guess in older times, you could get credit for a quote if you were the first in a country to use it. From <a href="http:&#x2F;&#x2F;quoteinvestigator.com&#x2F;2012&#x2F;04&#x2F;28&#x2F;shorter-letter&#x2F;" rel="nofollow">http:&#x2F;&#x2F;quoteinvestigator.com&#x2F;2012&#x2F;04&#x2F;28&#x2F;shorter-letter&#x2F;</a> it looks like Benjamin Franklin was among the first Americans. But then again, what can we really trust?<p>Maybe we should just attribute all quotes to Mark Twain and be done with it.
