1940s - Early 1950s: First Generation Computers Probably the most important contributor concerning the theoretical basis for the digital computers that were developed in the 1940s was Alan Turing, an English mathematician and logician. In 1936 he created the Turing machine, which was originally conceived as a mathematical tool that could infallibly recognize undecidable propositions. Although he instead proved that there cannot exist any universal method of determination, Turing's machine represented an idealized mathematical model that reduced the logical structure of any computing device to its essentials. His basic scheme of an input/output device, memory, and central processing unit became the basis for all subsequent digital computers. The onset of the Second World War led to an increased funding for computer projects, which hastened technical progress, as governments sought to develop computers to exploit their potential strategic importance. By 1941 the German engineer Konrad Zuse had developed a computer, the Z3, to design airplanes and missiles. Two years later the British completed a secret code-breaking computer called Colossus to decode German messages and by 1944 the Harvard engineer Howard H. Aiken had produced an all-electronic calculator, whose purpose was to create ballistic charts for the U.S. Navy. Also spurred by the war the Electronic Numerical Integrator and Computer (ENIAC), a general-purpose computer, was produced by a partnership between the U.S. government and the University of Pennsylvania (1943). Consisting of 18.000 vacuum tubes, 70.000 resistors and 5 million soldered joints, the computer was such a massive piece of machinery (floor space: 1,000 square feet) that it consumed 160 kilowatts of electrical power, enough energy to dim lights in an entire section of a bigger town. Concepts in computer design that remained central to computer engineering for the next 40 years were developed by the Hungarian-American mathematician John von Neumann in the mid-1940s. By 1945 he created the Electronic Discrete Variable Automatic Computer (EDVAC) with a memory to hold both a stored program as well as data. The key element of the Neumann architecture was the central processing unit (CPU), which allowed all computer functions to be coordinated through a single source. One of the first commercially available computers to take advantage of the development of the CPU was the UNIVAC I (1951). Both the U.S. Census bureau and General Electric owned UNIVACs (Universal Automatic Computer). Characteristic for first generation computers was the fact, that instructions were made-to-order for the specific task for which the computer was to be used. Each computer had a different binary-coded program called a machine language that told it how to operate. Therefore computers were difficult to program and limited in versatility and speed. Another feature of early computers was that they used vacuum tubes and magnetic drums for storage.

The 18th Century: Powered Machines and the Industrial Revolution The invention of the steam engine by James Watt in 1776 represented a major advance in the development of powered machines. It was first applied to an industrial operation - the spinning of cotton - in 1785. A new kind of work-slave it not only marked the beginning of the Industrial Revolution, but also the coming age of mass production. In the England of the 18th century five important inventions in the textile industry advanced the automation of work processes. 1) John Kay's flying shuttle in 1733 , which permitted the weaving of larger widths of cloth and significantly increased weaving speed, 2) Edmund Cartwright's power loom in 1785, which increased weaving speed still further, 3) James Hargreaves' spinning jenny in 1764, 4) Richard Arkwright's water frame and 5) Samuel Crompton's spinning mule in 1779, whereby the last three inventions improved the speed and quality of thread-spinning operations. Those developments, combined with the invention of the steam engine, in short time led to the creation of new machine-slaves and the mechanization of the production of most major goods, such as iron, paper, leather, glass and bricks. Large-scale machine production was soon applied in many manufacturing sectors and resulted in a reduction of production costs. Yet the widespread use of the novel work-slaves also led to new demands concerning the work force's qualifications. The utilization of machines enabled a differentiated kind of division of labor and eventuated in a (further) specialization of skills. While before many goods were produced by skilled craftsmen the use of modern machinery increased the demand for semiskilled and unskilled workers. Also, the nature of the work process altered from one mainly dependent on physical power to one primarily dominated by technology and an increasing proportion of the labor force employed to operate machines.

1913: Henry Ford and the Assembly Line Realizing that he'd need to lower costs Henry Ford (Ford Motor Company) was inspired to create a more efficient way to produce his cars. Looking at other industries he and his team found four principles, which furthered their goal: interchangeable parts, continuous flow, division of labor, and reducing wasted effort. The use of interchangeable parts meant making the individual pieces of the car the same every time. Therefore the machines had to be improved, but once they were adjusted, they could be operated by a low-skilled laborer. To reduce the time workers spent moving around Ford refined the flow of work in the manner that as one task was finished another began, with minimum time spent in set-up. Furthermore he divided the labor by breaking the assembly of the legendary Model T in 84 distinct steps. Frederick Taylor, the creator of "scientific management" was consulted to do time and motion studies to determine the exact speed at which the work should proceed and the exact motions workers should use to accomplish their tasks. Putting all those findings together in 1913 Ford installed the first moving assembly line that was ever used for large-scale manufacturing. His cars could then be produced at a record-breaking rate, which meant that he could lower the price, but still make a good profit by selling more cars. For the first time work processes were largely automated by machinery.
