    Gertrude Blanch can be viewed as either the last and most important leader of human computers or one of the first numerical analysts for electronic computers. From 1938 to 1948, she was the technical director of the Mathematical Tables Project, the largest and most sophisticated of the human computing groups. During that period, she organized the literature of computing and numerical analysis. After the Mathematical Tables Project became the Computation Laboratory of the National Bureau of Standards, Blanch went on to develop numerical analysis for the early computers, working first for the Institute for Numerical Analysis, next for the Computer Division of Consolidated Engineering (later ElectroData), and finally for the Air Force's Aeronautical Research Laboratory in Dayton, Ohio.

  • Comparison of electrical “engineering” of Heaviside's times and software “engineering” of our times

    In previous centuries, several technical fields that are now engineering disciplines exhibited problems analogous to those frequently observed in software development today. This paper presents selected examples of experiences from some of those fields, especially electrical telegraphy and telephony during the second half of the 19th and the early 20th centuries, and compares them with difficulties, major mistakes, and so on, arising in software development today. It is the thesis of this paper that software development today is in a pre-engineering phase, analogous in many respects to the pre-engineering phases of the now traditional engineering disciplines. From observations regarding similarities between experiences in those fields in the past and software development today, questions are raised regarding lessons that software developers might learn from those earlier experiences of others-in particular, from the solutions they found to their problems. Some answers are suggested View full abstract»

    The essence of the modern hashing technique in computer science is the derivation of a number from a nonnumeric key to index into a table where the record containing the key is stored. In this paper, an interestingly similar technique used in South Indian musicology in the 18th century is described, and the question of whether it is an anticipation of the hashing technique is briefly addressed. The problem of retrieving a record from a table based upon a given key has been studied extensively. In this paper, I describe one particular approach to this problem-hashing-and also an interesting earlier development very similar to it. It is generally believed that the idea of hashing was originated by H.P. Luhn (1953), and first described in the open literature by A.I. Dumey (1956), but is it possible that the Katapayadi scheme of deriving numbers from names-in conjunction with the applications to which it had been put, especially in classical South Indian musicology-is an early anticipation of the hashing technique? I discuss this issue in detail in this paper View full abstract»

    This paper addresses the initial development of the first punched-card system in the United States in the 1880s and the construction of the next punched-card machine generation, launched in 1907. Finally, aspects of punched-card systems in the 1910s give a perspective on this history View full abstract»
