Editorial Note
We searched Einstein's collected writings, his correspondence in the Einstein Archives, his essay collections such as *Ideas and Opinions* and *The World As I See It*, and the standard scholarly reference *The Ultimate Quotable Einstein* (Princeton University Press), and found no primary source in which Einstein wrote or spoke this line. What we did find is a clear documented lineage that predates and points away from him: Doris Lessing's 1957 novel *The Habit of Loving* contains the closely matching sentiment "Coincidence is the pseudonym God uses when He does not want to sign His name," which itself echoes Anatole France's 1894 *Le Jardin d'Épicure* ("Le hasard, c'est peut-être le pseudonyme de Dieu quand il ne voulait pas signer"). The exact modern wording circulates widely, and a book-database search turns up early appearances in David McFadden's *Gypsy Guitar* (1987) and later in *Sisterfriends* by Jewel Diamond Taylor (1998), none crediting Einstein and none tying the phrase to him. The pattern here is characteristic of a literary aphorism that migrated through quotation culture and later acquired Einstein's famous name for authority, rather than one he originated. Because we have a specific, citable earlier source for the underlying saying (Lessing, and before her France) and no documentary basis whatsoever for the Einstein credit, this is not merely unsupported but points affirmatively to a different origin. On the evidence available, we consider this quotation misattributed.
