Abstract:	This paper is derived primarily from the personal recollections of the authors, spanning the entire period in which navigation by the timing of radio signals has developed in this country. If there is a lesson to be learned from this fragmentary history, it is that the pressure of navigational requirements has always demanded more than our knowledtge of the facts of radio wave propagation cold supply. The systems reviewed have been constructed on the basis of, at best, empirical data or, at worst, guesses. Under these circumstances, new discoveries have, from time to time, brought forth new methods and new systems, while habit has tended to keep the older technique sin operation. These forces provide a partial explanation of a perhaps unfortunate proliferatio, some of which might have been avoided had research provided sounder theories and more precise data in advance of the demand for navigation aids having larger service areas and improved accuracy.
