Milton Friedman and David Meiselman’s 1963 article “The Relative Stability of Monetary Velocity and the Investment Multiplier in the United States, 1897-1958,” was one of the most influential studies to come out of the Keynesian-monetarist debates of the 1960s and 1970s. The gestation of the article, however, is shrouded with considerable inaccuracy and ambiguity. I use archival materials to provide a more accurate chronological ordering of the gestation of the article than has hitherto been available. I show that the gestation was subject to considerable delays because of Meiselman’s propensity to get side-tracked by other projects. I explain why a longpromised follow-up paper was never completed and why a book sequel to Friedman’s 1956, Studies in the Quantity Theory of Money, that had been planned as a co-edited work shortly after the appearance of the Friedman and Meiselman 1963 article, was not published until 1970 and was edited by Meiselman alone.
