Who is Ellen Parr and did she originate a famous quote? The December
1980 Reader's Digest ("Quotable Quotes") cited her, with no further
designation, as the originator of the oft-quoted words, "The cure for
boredom is curiosity. There is no cure for curiosity." But I find no
record of her in "Books in Print" or online. (She is not the Ellen
Parr who lives in America's northwest and has written a few online
articles about dogs.) The quote is less-often attributed to Dorothy Parker (see
http://www.library.csi.cuny.edu/dept/history/lavender/386/dparker.html,
for example), but it seems with no documentation. I have done a
cursory search through Parker's works in vain search of the quote.

After an extensive search, I found this quote attributed to Dorothy
Parker *almost* as often as it was attributed to Parr. But I was
unable to find citations at all. It may be that this quote was an
"overheard" phrase, or was given in a speech. In any case, I am
doubtful that Parr was an author; while one or two websites gave Parr
credit for this quote to "author Ellen Parr," I'm thinking they
*assumed* she was an author.

Wish I had a more definitive answer...maybe another researcher will
have better luck!

The catalogues of the Library of Congress and the British Library do
not contain any records for an Ellen Parr.

You're almost certainly right, I suspect, that the "author"
designation is an assumption. I also suspect that all the online Parr
attributions trace back to the 1980 Reader's Digest feature. Reader's
Digest has a reputation for researching its information thoroughly, so
I had thought of writing them, but I was doubtful that they would open
their archives for such a relatively trivial matter. So I'm hoping
I've found a knowledgeable and persistent Google snoop!

This reminds me of the Sister Mary Tricky question.
