    Volume 9 in the Babbage Reprint Series makes the Moore School Lectures (1946) available for the first time. Delivered by such notable engineers and scientists as J.P. Eckert, J. Mauchly, H. Goldstine, A.W. Burks, and J. von Neumann at the University of Pennsylvania as a direct response to crucial new developments in the design and construction of the early stored program computer, the ENIAC, the lectures provide a comprehensive overview of the history of computing devices and digital and analog computing mechanisms; machine elements, including arithmetic circuits and the Selectron; numerical mathematical methods; and a detailed presentation of the ENIAC, the parallel type EDVAC, and the serial acoustic binary EDVAC.

  • The Calculating Machines (Die Rechenmaschinen)

    Their History and Development

    Ernst Martin

    This final volume in the Charles Babbage Institute Reprint series brings to light an extremely rare German account of the calculating machine industry in the first quarter of this century when the use of office machines became common in American and European business, government, and science. Ernst Martin wrote Die Rechenmaschinen to address the issues and questions that the public had raised about the many calculating devices that were appearing on the market in the early 1920s. His little book is, in fact, a developmental history of calculating machines in catalog form - invaluable for collectors of old machines. The introduction describes the seven major types of machines that had been produced by 1925. The corpus of the book consists of a running list of specific calculating machines, arranged by the date the device was first patented or produced.

    Le Calcul Simplifié

    Graphical and Mechanical Methods for Simplifying Calculation

    Maurice d'Ocagne

    This first translation of d'Ocagne's Le Calcul Simplifié makes a classic work on the early art of computation available to historians of computer science.

    In the days before the sophisticated mechanical esk calculator and the later electronic devices, d'Ocagne's nomograms were highly regarded methods for performing calculations. This first translation of d'Ocagne's Le Calcul Simplifié makes a classic work on the early art of computation available to historians of computer science. Le Calcul Simplifié, first published in the early 1890s, is volume 11 in the Charles Babbage Institute Reprint Series.

  • Handbook of the Napier Tercentenary Celebration or Modern Instruments and Methods of Calculation

    E. M. Horsburgh

    This handbook was published in 1914 to accompany the Napier Tercentenary Exhibition.

    This handbook was published in 1914 to accompany the Napier Tercentenary Exhibition. It describes exhibits of all types of calculating machines, as well as mathematical literature, logarithmic tables, and objects of historical connection with John Napier, the man who discovered logarithms. It includes an account of Napier's life and times and gives a short description of how to use Napier's bones as well as more detailed descriptions of such measuring devices as. the abacus, slide rule, planimeters, harmonic analyzers, and differentiating machines. The material is illustrated with a large number of engravings, photographs, and diagrams. It is perhaps the best English language account of machines and techniques used for calculation before the first World War. The book is Volume III in the Charles Babbage Institute Reprint Series and was first published by G. Bell and Sons, Ltd., and the Royal Society of Edinburgh.
