Attributed to Inge in The Columbia Dictionary of Quotations (1993), which cites the London Observer, 14 February 1932. However, this aphorism was in circulation decades earlier, e.g., it features in an advertisement in The Grape Belt, 2 October 1906, p. 5 http://news.google.com/newspapers?id=LY9CAAAAIBAJ&sjid=tLkMAAAAIBAJ&pg=5967,3394664&dq=worry-is-interest-paid-on-trouble-before-it-falls-due&hl=en
