Abstract. In this paper an example is given of a separable Banach space with the Radon-Nikodym property that is not isomorphic to a subspace of a separable dual space.In [5] Uhl showed that if every separable closed linear subspace of a Banach space A" is isomorphic to a subspace of a separable dual, then X has the Radon-Nikodym property (RNP). In that same paper, he asked whether every separable Banach space X with the RNP is isomorphic to a subspace of a separable dual space. Three years later, in 1975, Stegall [4] showed that if X is a subspace of a dual space, then the answer to Uhl's question is yes. We present in this note an example which shows that for general Banach spaces the answer is no.
