First Edition of a pioneering work in computing, based on a series of lectures given at the University of Illinois in 1948. The first four chapters are devoted to analogue devices, particularly differential analyzers, including a device the author constructed in 1934 from toy parts. Chapter 5 is devoted to digital computers, which the author clearly prefers. Chapter 6 describes Babbages machines, with a discussion of Lady Lovelaces 1843 paper. Chapter 7 is on the Harvard Mark I & II calculators. Chapter 8 discusses various projects in development, including magnetic drums and tapes, Boolean algebra for circuit analysis and flowcharts for programming. There are brief accounts of the plans for several machines, including EDVAC, UNIVAC, and Mark III. The last chapter is a perspective survey of the prospects for numerical analysis. Goldstine p.99. Randell p.136: Includes fairly extensive discussion of Babbages work, the Harvard Mark I, ENIAC and the I.B.M. Selective Sequence Electronic Calculator.
