N2 - For D, a bounded Lipschitz domain in Rn, n ≥ 2, the classical layer potentials for Laplace's equation are shown to be invertible operators on L2(∂D) and various subspaces of L2(∂D). For 1 < p ≤ 2 and data in Lp(∂D) with first derivatives in Lp(∂D) it is shown that there exists a unique harmonic function, u, that solves the Dirichlet problem for the given data and such that the nontangential maximal function of ▽u is in Lp(∂D). When n = 2 the question of the invertibility of the layer potentials on every Lp(∂D), 1 < p < ∞, is answered.
