N2 - Landauer's principle that the world's entropy increases by at least k B h 2 upon a one-bit erasure in a memory coupled to an infinite heat bath is generalized to the nominally different case of dumping information past a black hole's event horizon. Specifically this idea is used to provide a lower bound on the black-hole entropy to horizon area ratio using onl y a modicum of classical general relativity and relativastic quantum mechanics; quantum field theoretic methods are not required. The dumping of free 1-D scalar-particle wave packets leads to an estimate of .181 for the lower bound of the said ratio. This compares well to the established value of exactly 114 for the ratio itself and contrasts with Bekenstein's original %formation theoretic" estimate of .028.
