Second Industrial Revolution
From Academic Kids
Several developments within the chemical, electrical, petroleum, and steel industries took place. Mass production of consumer goods also developed at this time, for the mechanisation of manufacture of food and drink, clothing and transport and even entertainment with the early cinema, radio and gramophone both served the needs of the population and also provided employment for the increasing numbers. This increasing production, however, was a factor leading up to the Long Depression and the so-called "New Imperialism".
Dating the era
The second industrial revolution is also called the second phase of the industrial revolution, since from a technological and a social point of view there is no clean break between the two. Indeed, it might be argued that it stems from the middle of the nineteenth century with the growth of railways and steam ships, for crucial inventions such as the Bessemer and the Siemens steel making processes were invented in the decades preceding 1871.
In the United States of America the Second Industrial Revolution is commonly associated with electrification as pioneered by Nikola Tesla, Thomas Alva Edison and George Westinghouse and by scientific management as applied by Frederick Winslow Taylor. The beginnings of wars offer a convenient milestone, since they have an effect on the capital needed to finance the useful application of new inventions. One might see the immediate beginnings of this period in the German annexation of Lorraine (an industrial area) following the Franco-Prussian War.
One of the most crucial inventions for the communication of technical ideas in this period was the steam-powered rotary printing press which was in fact a technological gift of the last decades of the first industrial revolution. This in turn had been developed as the result of the invention of the endless-web paper-making machine by Fourdrinier at the beginning of the nineteenth century. The second industrial revoution also saw the introduction of mechanical typesetting with the Linotype and the Monotype. This diffusion of knowledge in Britain, at least, was also the result of the repeal in the 1870s of taxes on paper which encouraged the growth of technical journalism and periodicals by cheapening production costs.
Inventions and their applications were much more diffuse in this Revolution (or phase of a revolution) than earlier. This period saw the growth of machine tools in America capable of making precision parts for assembly in other machines. It also saw the introduction of the assembly line for the producion of consumer goods.
The steam engine was developed and applied in Britain during the 18th century and only slowly exported to Europe and the rest of the world during the 19th century, along with the industrial revolution. In contrast, in the second industrial revolution practical developments of the internal-combustion engine appeared in several industrialized countries and the exchange of ideas was much faster. To give but one example, the first practical internal-combustion engine ran on coal gas and was developed in France by Etienne Lenoir, where it had a certain limited success as a stationary engine in light industry.
The internal-combustion engine was tried out as a motive force for primitive automobiles in France in the 1870s, but it never was produced in quantity. It was Gottlieb Daimler of Germany who really exploited the breakthrough of using petroleum instead of coal gas as a fuel, for the automobile a few years later. Then it was Henry Ford of the United States who, still later, made the internal combustion engine a mass market phenomenon with a tremendous effect on society. The two stroke petrol engine was initially invented by the British engineer Joseph Day of Bath, who later licenced it to American entrepreneurs whereupon is quickly became the 'poor man's power source', driving motor cycles, motor boats, pumps and a became cheap, reliable, driver of small workshops before the days of mains electricity.
- Germany, having industrialized after Britain, was able to model its factories after those of Britain thus saving a substantial amount of capital, effort, and time. While Germany made use of the latest technological concepts, the British continued to use expensive and outdated technology and therefore were unable (or unwilling) to afford the fruits of their own scientific progress.
- In the development of science and pure research, the Germans invested more heavily than the British.
- The German cartel system, being significantly concentrated, was able to make more efficient use of fluid capital.
This period, akin to the First Industrial Revolution was marked by a significant number of transient urban workers engaged in industrial labour (or the pursuit thereof), relatively common unemployment, low wages, and common prostitution due to the lack of other means of income. This period is also notable for an expanding number of white collar workers and increasing enrollment in socialist trade unions.
End of the second phase
The end of the second industrial revolution or second phase of the industrial revolution has not been properly defined, since it would mean that the beginning of the third phase of the industrial revolution would also have to be considered. This is a difficult problem for the core of the industrial revolution is often linked to power sources and power usage. The first phase of the industrial revolution had coal or wood-generated steam power at its core. The second phase of the industrial revolution had the internal combustion engine and electrical motors and generators at its core.
While some might surmise that the rise of nuclear power should mark the start of the third phase, it would clash with the fact that, with the exception of France, industrial economies depend less and less on nuclear power for their energy, and that, again with the exception of France, power from a nuclear reactor was never a major source of energy.
In the past, the term "second industrial revolution" has often been used in the popular press and by technologists or industrialists to refer to the changes following the spread of new technology after World War II. The excitement and the debate over the dangers and the benefits of the Atomic Age were more intense and lasting than that over the Space age but they both were perceived (separately or together) to lead to another industrial revolution. At the start of the 21st century the term "second industrial revolution" has also been used to describe the anticipated effects of hypothetical molecular nanotechnology systems upon society. In this more recent scenario, the nanofactory would render the majority of today's modern manufacturing processes obsolete, vastly impacting all facets of the modern economy.
