evidence: A post on Facebook alleges that Irish poet and playwright Oscar Wilde once said, "Some cause happiness wherever they go; others whenever they go." [...] Wilde was a poet, novelist and playwright who featured prominently in the aestheticism movement, in which beauty was considered to be the primary purpose of art. Two of his best known works, the 1895 satirical play "The Importance of Being Earnest" and the 1891 philosophical novel "The Picture of Dorian Gray," are both considered literary classics. [...] The expression, attributed to an anonymous author, appeared below an actual Wilde quote in a 1947 book called "A Little Book of Aphorisms," according to the website Quote Investigator, though variations of the saying have appeared in print as early as 1908.
