Of all of the artifacts of 20th-century technology, the computer has had the greatest impact on the culture of science, technology, and business. The first successful computers emerged in scientific and engineering laboratories in the 1930s and 1940s. In this little book, James Cortada portrays the commercialization of the computer in the 1950s and accounts for its acceptance by the business machine indus try, whose market the computer penetrated. In so doing, Cortada carries forward an argument begun with his earlier book, Before the Computer, that continuity, rather than change, and evolution, rather than revolution, express the development of the computer from 1865 through the 1950s. The evolutionary meta phor is borrowed from George Basalla. It serves to underscore the importance of office machinery as the progenitors of computers, of the relation of machina recta to machina sapienta. The missing link in this evolution is the scientific computer, whose career Cortada traces from its origins in the analog, electromechani cal, and digital machines of the 1930s and 1940s. These last two were variants, in a manner of speaking, of the office machines, while the analog computer sprang from a different tradition, stretching back two thousand years. The preconditions for the emergence of scientific computing were developments in mathematics and information the ory that supplied a binary logic and architecture and in electrical engineering that provided for switching and relays. In the cauldron of war, these provided the underpinning of the first electronic digital computers, like ENIAC. Born in the laboratory, scientific computers offered little to the traditional makers of office machines at first. The punch-card equip ment that had served the needs of the business community and been permuted for wartime calculations at Los Alamos and elsewhere seemed to meet market needs. The development of the Harvard Mark I, an IBM-sponsored machine, led the company to create the 206 Book Reviews TECHNOLOGY AND CULTURE Selective Sequence Calculator after the war, but that was a showcase computer rather than a prototype for IBM’s product line. The evolu tion of scientific computing eventually produced machines like the UNIVAC and the IBM 701, which found only incidental commercial applications. In transforming office calculating equipment to electronics, the punched-card paradigm initially dominated IBM and its competi tors. Only after it became obvious, thanks in part to governmentsupported research and development, that the digital computer could replace its traditional lines in the marketplace was IBM ready to com mit to a strategy of a commercial product line of computers in the 650 series. By that time, Cortada argues, the technical and business community had been introduced to the computer through trade and mass-market publications. Technically oriented personnel in com mercial firms could appreciate the contribution these machines might make to their operations. Companies like IBM could respond and, with a strong service relationship, influence their customers to re spond. By 1960, computing had become a $1 billion industry. Although computers shared with other 20th-century technologies a substantial scientific and technical heritage and, like most of them, required considerable public investment in their development, they found widespread application largely by following the channels of commerce that had been carved out by office-equipment manufactur ers, in Cortada’s view. Although he recognizes his “office equipocentrism ,” Cortada defends it as consistent with the goal of tracing the computer from laboratory to market. If one were to trace its development in scientific and engineering applications or in cryptol ogy, different paths would presumably...
