DESCRIPTION:We derive a concrete closed string dual to any interacting\nHe
 rmitian one-matrix model\, away from the double-scaling limit. Matrix\nand
  string correlators are shown to manifestly agree\, to all orders in\nthe 
 genus expansion and all orders in the 't Hooft coupling(s).\n\nThe worldsh
 eet theory consists of a supersymmetric B-twisted\nLandau--Ginzburg model 
 coupled to two-dimensional topological gravity.\nWe provide a precise dict
 ionary between traces of the matrix and vertex\noperators on the worldshee
 t. Matrix model observables are explicitly\nmapped to computable integrals
  over the moduli-space of Riemann\nsurfaces. We perform several cross-chec
 ks by direct computation on both\nsides of the duality.\n\nThis work furni
 shes an finite-dimensional instantiation of gauge/string\nduality\, in the
  standard 't Hooft limit\, and hopefully a useful\nworldsheet toy model fo
 r the AdS/CFT correspondence.
