Abstract In 1946, P. Erdős and I. Niven proved that there are only finitely many positive integers n for which one or more of the elementary symmetric functions of 1, 1⁄2, …, 1⁄n are integers. In this paper we prove that if n ≥ 4, then none of the elementary symmetric functions of 1, 1⁄2, …, 1⁄n are integers.
