Charles Holt's classic paper on exponentially weighted moving averages appeared as Report ONR 52 from the Office of Naval Research in 1957. Although widely cited, the full version has remained unpublished. This note provides some context for looking back to ONR 52. We indicate that the paper still has some lessons for modern practice, in terms of both method specification and method choice.
