A Week-End Off: The First Extensive Number-Theoretical Computation on the ENIAC

Abstract : The first extensive number-theoretical computation run on the ENIAC, is reconstructed. The problem, computing the exponent of 2 modulo a prime, was set up on the ENIAC during a weekend in July 1946 by the number-theorist D.H. Lehmer, with help from his wife Emma and John Mauchly. Important aspects of the ENIAC's design are presented and the reconstruction of the implementation of the problem on the ENIAC is discussed in its salient points.
