When the simulation department of Management Science was created in 1978 it ushered in an era of significant methodological advances in stochastic simulation. However, the foundation for the fieldnot just the work that has been published in Management Sciencewas provided by two papers published long before simulation had its own department in the journal. We will review the seminal papers of Conway, Johnson, and Maxwell (1959) and Conway (1963), and then trace their impact through eight award-winning papers that appeared much later in Management Science.
