Georges Duhamel in THE HEART'S DOMAIN (1919). As it was composed in French, the wording in English may vary in translation. Theodore Geisel / Dr. Seuss was born in 1904, and would have been about 15 years old at the time that it was published. The full text can be found at the link below: We do not know the true value of our moments until they have undergone the test of memory. Like the images the photographer plunges into a golden bath, our sentiments take on color; and only then, after that recoil and that trans-figuration, do we understand their real meaning and enjoy them in all their tranquil splendor.

Frequently attributed to Nin, but without cited source in her work (possibly due to a quotation in Living on Purpose: Straight Answers to Universal Questions (2000) by Dan Millman that attributed the quote to Nin without source).
In March 2013, a former Director of Public Relations at John F. Kennedy University in Orinda, Elizabeth Appell, claimed she had authored the quote in 1979 for an inspirational header on a class schedule: http://anaisninblog.skybluepress.com/2013/03/who-wrote-risk-is-the-mystery-solved/

Often attributed to Churchill, this thought was originally expressed by the French author Victor Hugo in Villemain (1845), as follows: You have enemies? Why, it is the story of every man who has done a great deed or created a new idea. It is the cloud which thunders around everything that shines. Fame must have enemies, as light must have gnats. Do not bother yourself about it; disdain. Keep your mind serene as you keep your life clear.
Villemain is a brief segment taken from Hugo’s Choses Vues (Things Seen), a running journal Hugo kept of events he witnessed. The original French versions of these journals were published after Hugo's death.

Although this maxim is associated with Wiesenthal (e.g. "Honoring Simon Wiesenthal", Congressional Record—House, Vol. 151, Pt. 15, 21 September 2005, p. 20804), he did not originate the quote, which appears in the context of the labor movement in the 19th century (e.g. Alexander Spencer, "Maintain Your Union", The Typographical Journal, Vol. 10, No. 7, 1 April 1897, p. 266).
