N2 - Let G be an adjoint finite group of Lie type. In this paper we classify the irreducible characters of G which appear with multiplicity 1 in any Gelfand–Graev character of G. Except for groups of type 2^A_2m and 2^G_2, this property identifies the Steinberg character of G (modulo linear characters).
