Leipzig
–
Leipzig is the largest city in the federal state of Saxony, Germany. With a population of 570,087 inhabitants it is Germanys tenth most populous city, Leipzig is located about 160 kilometres southwest of Berlin at the confluence of the White Elster, Pleisse, and Parthe rivers at the southern end of the North German Plain. Leipzig has been a city since at least the time of the Holy Roman Empire. The city sits at the intersection of the Via Regia and Via Imperii, Leipzig was once one of the major European centers of learning and culture in fields such as music and publishing. Leipzig became an urban center within the German Democratic Republic after the Second World War. Leipzig later played a significant role in instigating the fall of communism in Eastern Europe, through events which took place in, Leipzig today is an economic center and the most livable city in Germany, according to the GfK marketing research institution. Since the opening of the Leipzig City Tunnel in 2013, Leipzig forms the centerpiece of the S-Bahn Mitteldeutschland public transit system, Leipzig is currently listed as Gamma World City and Germanys Boomtown. Outside of Leipzig the Neuseenland district forms a lake area of approximately 300 square kilometres. Leipzig is derived from the Slavic word Lipsk, which means settlement where the linden trees stand, an older spelling of the name in English is Leipsic. The Latin name Lipsia was also used, the name is cognate with Lipetsk in Russia and Liepāja in Latvia. In 1937 the Nazi government officially renamed the city Reichsmessestadt Leipzig, the common usage of this nickname for Leipzig up until the present is reflected, for example, in the name of a popular blog for local arts and culture, Heldenstadt. de. Leipzig was first documented in 1015 in the chronicles of Bishop Thietmar of Merseburg as urbs Libzi and endowed with city, Leipzig Trade Fair, started in the Middle Ages, became an event of international importance and is the oldest remaining trade fair in the world. During the Thirty Years War, two battles took place in Breitenfeld, about 8 kilometres outside Leipzig city walls, the first Battle of Breitenfeld took place in 1631 and the second in 1642. Both battles resulted in victories for the Swedish-led side, on 24 December 1701, an oil-fueled street lighting system was introduced. The city employed light guards who had to follow a schedule to ensure the punctual lighting of the 700 lanterns. The Leipzig region was the arena of the 1813 Battle of Leipzig between Napoleonic France and a coalition of Prussia, Russia, Austria and Sweden. It was the largest battle in Europe prior to the First World War, in 1913 the Monument to the Battle of the Nations celebrating the centenary of this event was completed. The railway station has two entrance halls, the eastern one for the Royal Saxon State Railways and the western one for the Prussian state railways

Germany
–
Germany, officially the Federal Republic of Germany, is a federal parliamentary republic in central-western Europe. It includes 16 constituent states, covers an area of 357,021 square kilometres, with about 82 million inhabitants, Germany is the most populous member state of the European Union. After the United States, it is the second most popular destination in the world. Germanys capital and largest metropolis is Berlin, while its largest conurbation is the Ruhr, other major cities include Hamburg, Munich, Cologne, Frankfurt, Stuttgart, Düsseldorf and Leipzig. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity, a region named Germania was documented before 100 AD. During the Migration Period the Germanic tribes expanded southward, beginning in the 10th century, German territories formed a central part of the Holy Roman Empire. During the 16th century, northern German regions became the centre of the Protestant Reformation, in 1871, Germany became a nation state when most of the German states unified into the Prussian-dominated German Empire. After World War I and the German Revolution of 1918–1919, the Empire was replaced by the parliamentary Weimar Republic, the establishment of the national socialist dictatorship in 1933 led to World War II and the Holocaust. After a period of Allied occupation, two German states were founded, the Federal Republic of Germany and the German Democratic Republic, in 1990, the country was reunified. In the 21st century, Germany is a power and has the worlds fourth-largest economy by nominal GDP. As a global leader in industrial and technological sectors, it is both the worlds third-largest exporter and importer of goods. Germany is a country with a very high standard of living sustained by a skilled. It upholds a social security and universal health system, environmental protection. Germany was a member of the European Economic Community in 1957. It is part of the Schengen Area, and became a co-founder of the Eurozone in 1999, Germany is a member of the United Nations, NATO, the G8, the G20, and the OECD. The national military expenditure is the 9th highest in the world, the English word Germany derives from the Latin Germania, which came into use after Julius Caesar adopted it for the peoples east of the Rhine. This in turn descends from Proto-Germanic *þiudiskaz popular, derived from *þeudō, descended from Proto-Indo-European *tewtéh₂- people, the discovery of the Mauer 1 mandible shows that ancient humans were present in Germany at least 600,000 years ago. The oldest complete hunting weapons found anywhere in the world were discovered in a mine in Schöningen where three 380, 000-year-old wooden javelins were unearthed

Austria
–
Austria, officially the Republic of Austria, is a federal republic and a landlocked country of over 8.7 million people in Central Europe. It is bordered by the Czech Republic and Germany to the north, Hungary and Slovakia to the east, Slovenia and Italy to the south, the territory of Austria covers 83,879 km2. The terrain is mountainous, lying within the Alps, only 32% of the country is below 500 m. The majority of the population speaks local Bavarian dialects of German as their native language, other local official languages are Hungarian, Burgenland Croatian, and Slovene. The origins of modern-day Austria date back to the time of the Habsburg dynasty, from the time of the Reformation, many northern German princes, resenting the authority of the Emperor, used Protestantism as a flag of rebellion. Following Napoleons defeat, Prussia emerged as Austrias chief competitor for rule of a greater Germany, Austrias defeat by Prussia at the Battle of Königgrätz, during the Austro-Prussian War of 1866, cleared the way for Prussia to assert control over the rest of Germany. In 1867, the empire was reformed into Austria-Hungary, Austria was thus the first to go to war in the July Crisis, which would ultimately escalate into World War I. The First Austrian Republic was established in 1919, in 1938 Nazi Germany annexed Austria in the Anschluss. This lasted until the end of World War II in 1945, after which Germany was occupied by the Allies, in 1955, the Austrian State Treaty re-established Austria as a sovereign state, ending the occupation. In the same year, the Austrian Parliament created the Declaration of Neutrality which declared that the Second Austrian Republic would become permanently neutral, today, Austria is a parliamentary representative democracy comprising nine federal states. The capital and largest city, with a population exceeding 1.7 million, is Vienna, other major urban areas of Austria include Graz, Linz, Salzburg and Innsbruck. Austria is one of the richest countries in the world, with a nominal per capita GDP of $43,724, the country has developed a high standard of living and in 2014 was ranked 21st in the world for its Human Development Index. Austria has been a member of the United Nations since 1955, joined the European Union in 1995, Austria also signed the Schengen Agreement in 1995, and adopted the euro currency in 1999. The German name for Austria, Österreich, meant eastern realm in Old High German, and is cognate with the word Ostarrîchi and this word is probably a translation of Medieval Latin Marchia orientalis into a local dialect. Austria was a prefecture of Bavaria created in 976, the word Austria is a Latinisation of the German name and was first recorded in the 12th century. Accordingly, Norig would essentially mean the same as Ostarrîchi and Österreich, the Celtic name was eventually Latinised to Noricum after the Romans conquered the area that encloses most of modern-day Austria, around 15 BC. Noricum later became a Roman province in the mid-first century AD, heers hypothesis is not accepted by linguists. Settled in ancient times, the Central European land that is now Austria was occupied in pre-Roman times by various Celtic tribes, the Celtic kingdom of Noricum was later claimed by the Roman Empire and made a province

Franco-Prussian War
–
The conflict was caused by Prussian ambitions to extend German unification and French fears of the shift in the European balance of power that would result if the Prussians succeeded. On 16 July 1870, the French parliament voted to declare war on the German Kingdom of Prussia, the German coalition mobilised its troops much more quickly than the French and rapidly invaded northeastern France. The German forces were superior in numbers, had training and leadership and made more effective use of modern technology, particularly railroads. The German states proclaimed their union as the German Empire under the Prussian king Wilhelm I, the Treaty of Frankfurt of 10 May 1871 gave Germany most of Alsace and some parts of Lorraine, which became the Imperial territory of Alsace-Lorraine. French determination to regain Alsace-Lorraine and fear of another Franco-German war, along with British apprehension about the balance of power, the causes of the Franco-Prussian War are deeply rooted in the events surrounding the unification of Germany. In the aftermath of the Austro-Prussian War of 1866, Prussia had annexed numerous territories and this new power destabilized the European balance of power established by the Congress of Vienna in 1815 after the Napoleonic Wars. France was strongly opposed to any further alliance of German states, in Prussia, some officials considered a war against France both inevitable and necessary to arouse German nationalism in those states that would allow the unification of a great German empire. Bismarck also knew that France should be the aggressor in the conflict to bring the southern German states to side with Prussia, many Germans also viewed the French as the traditional destabilizer of Europe, and sought to weaken France to prevent further breaches of the peace. The immediate cause of the war resided in the candidacy of Leopold of Hohenzollern-Sigmaringen, France feared encirclement by an alliance between Prussia and Spain. The Hohenzollern princes candidacy was withdrawn under French diplomatic pressure, releasing the Ems Dispatch to the public, Bismarck made it sound as if the king had treated the French envoy in a demeaning fashion, which inflamed public opinion in France. They also argue that he wanted a war to resolve growing domestic political problems, other historians, notably French historian Pierre Milza, dispute this. According to Milza, the Emperor had no need for a war to increase his popularity, the Ems telegram had exactly the effect on French public opinion that Bismarck had intended. This text produced the effect of a red flag on the Gallic bull, gramont, the French foreign minister, declared that he felt he had just received a slap. Napoleons new prime minister, Emile Ollivier, declared that France had done all that it could humanly and honorably do to prevent the war, a crowd of 15–20,000 people, carrying flags and patriotic banners, marched through the streets of Paris, demanding war. On 19 July 1870 a declaration of war was sent to the Prussian government, the southern German states immediately sided with Prussia. The French Army consisted in peacetime of approximately 400,000 soldiers, some of them were veterans of previous French campaigns in the Crimean War, Algeria, the Franco-Austrian War in Italy, and in the Mexican campaign. Under Marshal Adolphe Niel, urgent reforms were made, universal conscription and a shorter period of service gave increased numbers of reservists, who would swell the army to a planned strength of 800,000 on mobilisation. Those who for any reason were not conscripted were to be enrolled in the Garde Mobile, however, the Franco-Prussian War broke out before these reforms could be completely implemented

Business cycle
–
The business cycle or economic cycle is the downward and upward movement of gross domestic product around its long-term growth trend. The length of a cycle is the period of time containing a single boom. These fluctuations typically involve shifts over time periods of relatively rapid economic growth, and periods of relative stagnation or decline. Business cycles are usually measured by considering the rate of real gross domestic product. Despite the often-applied term cycles, these fluctuations in economic activity do not exhibit uniform or predictable periodicity, the common or popular usage boom-and-bust cycle refers to fluctuations in which the expansion is rapid and the contraction severe. Prior to that point classical economics had either denied the existence of cycles, blamed them on external factors, notably war. Sismondi found vindication in the Panic of 1825, which was the first unarguably international economic crisis and they advocated government intervention and socialism, respectively, as the solution. He devoted hundreds of pages of Das Kapital to crises, in Progress and Poverty, Henry George focused on lands role in crises – particularly land speculation – and proposed a single tax on land as a solution. In 1860 French economist Clement Juglar first identified economic cycles 7 to 11 years long, interest in the different typologies of cycles has waned since the development of modern macroeconomics, which gives little support to the idea of regular periodic cycles. There were great increases in productivity, industrial production and real per capita product throughout the period from 1870 to 1890 that included the Long Depression, there were also significant increases in productivity in the years leading up to the Great Depression. Both the Long and Great Depressions were characterized by overcapacity and market saturation, the effect of technological progress can be seen by the purchasing power of an average hours work, which has grown from $3 in 1900 to $22 in 1990, measured in 2010 dollars. There were similar increases in wages during the 19th century. See Financial crisis, 19th century for listing and details, the first of these crises not associated with a war was the Panic of 1825. Business cycles in OECD countries after World War II were generally more restrained than the business cycles. This was particularly true during the Golden Age of Capitalism, in this period, the economic cycle – at least the problem of depressions – was twice declared dead. The first declaration was in the late 1960s, when the Phillips curve was seen as being able to steer the economy, however, this was followed by stagflation in the 1970s, which discredited the theory. The second declaration was in the early 2000s, following the stability, notably, in 2003, Robert Lucas, in his presidential address to the American Economic Association, declared that the central problem of depression-prevention been solved, for all practical purposes. Unfortunately, this was followed by the 2008–2012 global recession, various regions have experienced prolonged depressions, most dramatically the economic crisis in former Eastern Bloc countries following the end of the Soviet Union in 1991

Entrepreneurship
–
What appears as a real opportunity ex ante might actually be a non-opportunity or one that cannot be actualized by entrepreneurs lacking the necessary business skills, financial or social capital. Traditionally, an entrepreneur has been defined as a person who starts, organizes and manages any enterprise, especially a business, usually with considerable initiative and risk. Rather than working as an employee, an entrepreneur runs a business and assumes all the risk and reward of a given business venture, idea. The entrepreneur is commonly seen as a leader and innovator of new ideas. They act as the manager and oversee the launch and growth of an enterprise, Entrepreneurship is the process by which an individual identifies a business opportunity and acquires and deploys the necessary resources required for its exploitation. For Schumpeter, the changes and dynamic disequilibrium brought on by the innovating entrepreneur, the ‘norm’ of a healthy economy. Entrepreneurial spirit is characterized by innovation and risk-taking, for example, in the 2000s, the field of social entrepreneurship has been identified, in which entrepreneurs combine business activities with humanitarian, environmental or community goals. In the 2010s, entrepreneurship can be studied in college or university as part of the disciplines of management or business administration, Entrepreneur, is a loanword from French. First used in 1723, today the term entrepreneur implies qualities of leadership, initiative, economist Robert Reich has called team-building, leadership, and management ability essential qualities for the entrepreneur. Historically the study of entrepreneurship reaches back to the work in the late 17th and early 18th centuries of Richard Cantillon and Adam Smith, which was foundational to classical economics. In the 20th century, entrepreneurship was studied by Joseph Schumpeter in the 1930s and other Austrian economists such as Carl Menger, Ludwig von Mises, the term entrepreneurship was coined around the 1920s, while the loan from French of the word entrepreneur dates to the 1850s. According to Schumpeter, an entrepreneur is willing and able to convert a new idea or invention into a successful innovation, thus, creative destruction is largely responsible for long-term economic growth. The idea that leads to economic growth is an interpretation of the residual in endogenous growth theory. For Schumpeter, entrepreneurship resulted in new industries and in new combinations of currently existing inputs, Schumpeters initial example of this was the combination of a steam engine and then current wagon making technologies to produce the horseless carriage. In this case the innovation, the car, was transformational and it did not immediately replace the horse-drawn carriage, but in time, incremental improvements reduced the cost and improved the technology, leading to the modern auto industry. Despite Schumpeters early 20th-century contributions, traditional microeconomic theory did not formally consider the entrepreneur in its theoretical frameworks, in this treatment, the entrepreneur was an implied but unspecified actor, consistent with the concept of the entrepreneur being the agent of x-efficiency. For Schumpeter, the entrepreneur did not bear risk, the capitalist did, Schumpeter was of the opinion that entrepreneurs shift the Production Possibility Curve to a higher level using innovations. Cantillon emphasized the willingness of the entrepreneur to assume risk and to deal with uncertainty, thus, he draws attention to the function of the entrepreneur, and distinguishes clearly between the function of the entrepreneur and the owner who provides the money

Locomotive
–
A locomotive or engine is a rail transport vehicle that provides the motive power for a train. A locomotive has no payload capacity of its own, and its purpose is to move the train along the tracks. In contrast, some trains have self-propelled payload-carrying vehicles and these are not normally considered locomotives, and may be referred to as multiple units, motor coaches or railcars. The use of these vehicles is increasingly common for passenger trains. Traditionally, locomotives pulled trains from the front, however, push-pull operation has become common, where the train may have a locomotive at the front, at the rear, or at each end. Prior to locomotives, the force for railroads had been generated by various lower-technology methods such as human power, horse power. The first successful locomotives were built by Cornish inventor Richard Trevithick, in 1804 his unnamed steam locomotive hauled a train along the tramway of the Penydarren ironworks, near Merthyr Tydfil in Wales. Although the locomotive hauled a train of 10 long tons of iron and 70 passengers in five wagons over nine miles, the locomotive only ran three trips before it was abandoned. Trevithick built a series of locomotives after the Penydarren experiment, including one which ran at a colliery in Tyneside in northern England, the first commercially successful steam locomotive was Matthew Murrays rack locomotive, Salamanca, built for the narrow gauge Middleton Railway in 1812. This was followed in 1813 by the Puffing Billy built by Christopher Blackett and William Hedley for the Wylam Colliery Railway, Puffing Billy is now on display in the Science Museum in London, the oldest locomotive in existence. In 1814 George Stephenson, inspired by the locomotives of Trevithick. He built the Blücher, one of the first successful flanged-wheel adhesion locomotives, Stephenson played a pivotal role in the development and widespread adoption of steam locomotives. His designs improved on the work of the pioneers, in 1825 he built the Locomotion for the Stockton and Darlington Railway, north east England, which became the first public steam railway. In 1829 he built The Rocket which was entered in and won the Rainhill Trials and this success led to Stephenson establishing his company as the pre-eminent builder of steam locomotives used on railways in the United Kingdom, the United States and much of Europe. The first inter city passenger railway, Liverpool and Manchester Railway, opened in 1830, there are a few basic reasons to isolate locomotive train power, as compared to self-propelled vehicles. Maximum utilization of power cars Separate locomotives facilitate movement of costly motive power assets as needed, flexibility Large locomotives can substitute for small locomotives when more power is required, for example, where grades are steeper. As needed, a locomotive can be used for freight duties. Obsolescence cycles Separating motive power from payload-hauling cars enables replacement without affecting the other, to illustrate, locomotives might become obsolete when their associated cars did not, and vice versa

August Borsig
–
Johann Friedrich August Borsig was a German businessman who founded the Borsig-Werke factory. Borsig was born in Breslau, the son of cuirassier and carpenter foreman Johann George Borsig, after learning his fathers trade, he first attended the Königliche Provinzial-Kunst- und Bauschule, then until fall of 1825 the Königliche Gewerbe-Institut. He received his training in engine construction at the Neue Berliner Eisengießerei of F. A. Egells. After the successful completion of task, Borsig was made factory manager for eight years. In 1828, he married Louise Pahl, they had one son, from early on, Borsig was a supporter of railroads. The founding date was declared to be 22 July 1837, the day of the first successful casting in the foundry, despite tremendous costs, the first locomotive, bearing factory number 1 and the name BORSIG, was finished in 1840. This locomotive had a frame, a two-axle front pivoted bogie. On 21 July 1840, Borsig let it compete against a Stephenson-built locomotive on the Berlin-Jüterbog railroad, after this victory, the number of orders rose quickly. A further six machines of this type were sold to the Berlin-Stettiner Eisenbahn, in the beginning, the Borsig company also built steam engines for their own needs and machines for other companies as well as cast parts for art and construction. However, the focus shifted to locomotive building, and the name Borsig is connected with locomotives to this day. By 1843, railway companies in Prussia had ordered 18 locomotives, the one hundredth locomotive was finished in 1846. Meanwhile, Borsig built the steam pump for the fountain at Sanssouci and participated in the building of the domes of the Nicolai Church in Potsdam, the company was expanding rapidly in those years, since new railways were being built all over Germany. In 1847, construction of the new Moabit ironworks started and they became operational in 1849, the increasing number of orders also increased Borsigs private wealth, and he soon became a rich entrepreneur who was not averse to splendor and a patron for many artists. August Borsig was said to be a strict but just boss with a zest for action, for his workers, he set up a sickness fund, a funeral expense fund, and a savings bank. His company had a room, a dining room and a bath with swimming pool. Borsig had become important by the end of the 1840s that he was able to weather the economic crisis of 1848-1852 with little damage. Starting 1851, foreign companies also began to order Borsig locomotives, among them the Warsaw-Vienna Railway. After the 500th locomotive had been completed in 1854, Borsig was made Geheimer Kommerzienrat and this allowed him to tighten his monopoly position, and 67 of the 68 new Prussian locomotives in 1854 came from Borsig factories

Berlin
–
Berlin is the capital and the largest city of Germany as well as one of its constituent 16 states. With a population of approximately 3.5 million, Berlin is the second most populous city proper, due to its location in the European Plain, Berlin is influenced by a temperate seasonal climate. Around one-third of the area is composed of forests, parks, gardens, rivers. Berlin in the 1920s was the third largest municipality in the world, following German reunification in 1990, Berlin once again became the capital of all-Germany. Berlin is a city of culture, politics, media. Its economy is based on high-tech firms and the sector, encompassing a diverse range of creative industries, research facilities, media corporations. Berlin serves as a hub for air and rail traffic and has a highly complex public transportation network. The metropolis is a popular tourist destination, significant industries also include IT, pharmaceuticals, biomedical engineering, clean tech, biotechnology, construction and electronics. Modern Berlin is home to world renowned universities, orchestras, museums and its urban setting has made it a sought-after location for international film productions. The city is known for its festivals, diverse architecture, nightlife, contemporary arts. Since 2000 Berlin has seen the emergence of a cosmopolitan entrepreneurial scene, the name Berlin has its roots in the language of West Slavic inhabitants of the area of todays Berlin, and may be related to the Old Polabian stem berl-/birl-. All German place names ending on -ow, -itz and -in, since the Ber- at the beginning sounds like the German word Bär, a bear appears in the coat of arms of the city. It is therefore a canting arm, the first written records of towns in the area of present-day Berlin date from the late 12th century. Spandau is first mentioned in 1197 and Köpenick in 1209, although these areas did not join Berlin until 1920, the central part of Berlin can be traced back to two towns. Cölln on the Fischerinsel is first mentioned in a 1237 document,1237 is considered the founding date of the city. The two towns over time formed close economic and social ties, and profited from the right on the two important trade routes Via Imperii and from Bruges to Novgorod. In 1307, they formed an alliance with a common external policy, in 1415 Frederick I became the elector of the Margraviate of Brandenburg, which he ruled until 1440. In 1443 Frederick II Irontooth started the construction of a new palace in the twin city Berlin-Cölln

Hanover
–
At the end of the Napoleonic Wars, the Electorate was enlarged to become a Kingdom with Hanover as its capital. From 1868 to 1946 Hanover was the capital of the Prussian Province of Hanover and it is now the capital of the Land of Lower Saxony. Since 2001 it has been part of the Hanover district, which is a body made up from the former district. With a population of 518,000, Hanover is a centre of Northern Germany. Hanover also hosts annual commercial trade fairs such as the Hanover Fair, every year Hanover hosts the Schützenfest Hannover, the worlds largest marksmens festival, and the Oktoberfest Hannover, the second largest such festival in Germany. In 2000, Hanover hosted the world fair Expo 2000, the Hanover fairground, due to numerous extensions, especially for the Expo 2000, is the largest in the world. Hanover is of importance because of its universities and medical school, its international airport. The city is also a crossing point of railway lines and highways. Hanover is the traditional English spelling, the German spelling is becoming more popular in English, recent editions of encyclopaedias prefer the German spelling, and the local government uses the German spelling on English websites. The traditional English spelling is used in historical contexts, especially when referring to the British House of Hanover. Hanover was founded in times on the east bank of the River Leine. Its original name Honovere may mean high bank, though this is debated, Hanover was a small village of ferrymen and fishermen that became a comparatively large town in the 13th century due to its position at a natural crossroads. As overland travel was difficult, its position on the upper navigable reaches of the river helped it to grow by increasing trade. In the 14th century the churches of Hanover were built. The beginning of industrialization in Germany led to trade in iron and silver from the northern Harz Mountains, in 1636 George, Duke of Brunswick-Lüneburg, ruler of the Brunswick-Lüneburg principality of Calenberg, moved his residence to Hanover. The Dukes of Brunswick-Lüneburg were elevated by the Holy Roman Emperor to the rank of Prince-Elector in 1692, thus the principality was upgraded to the Electorate of Brunswick-Lüneburg, colloquially known as the Electorate of Hanover after Calenbergs capital. Its electors would later become monarchs of Great Britain, the first of these was George I Louis, who acceded to the British throne in 1714. The last British monarch who ruled in Hanover was William IV, semi-Salic law, which required succession by the male line if possible, forbade the accession of Queen Victoria in Hanover

Bessemer process
–
The Bessemer process was the first inexpensive industrial process for the mass-production of steel from molten pig iron before the development of the open hearth furnace. The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron, the oxidation also raises the temperature of the iron mass and keeps it molten. Related decarburizing with air processes had been used outside Europe for hundreds of years, one such process has existed since the 11th century in East Asia, where the scholar Shen Kuo describes its use in the Chinese iron and steel industry. In the 17th century, accounts by European travelers detailed its possible use by the Japanese, the modern process is named after its inventor, the Englishman Henry Bessemer, who took out a patent on the process in 1856. The process was said to be discovered in 1851 by the American inventor William Kelly. The process using a basic refractory lining is known as the basic Bessemer process or Gilchrist–Thomas process after the English discoverers Percy Gilchrist and these oxides either escape as gas or form a solid slag. The refractory lining of the converter also plays a role in the conversion — clay linings are used there is little phosphorus in the raw material - this is known as the acid Bessemer process. When the phosphorus content is high, dolomite, or sometimes magnesite and these are also known as Gilchrist-Thomas converters, after their inventor, Sidney Gilchrist Thomas. In order to produce steel with desired properties, additives such as spiegeleisen, when the required steel had been formed, it was poured into ladles and then transferred into moulds while the lighter slag was left behind. The conversion process, called the blow, was completed in approximately 20 minutes, during this period the progress of the oxidation of the impurities was judged by the appearance of the flame issuing from the mouth of the converter. The modern use of methods of recording the characteristics of the flame greatly aided the blower in controlling final product quality. After the blow, the metal was recarburized to the desired point and other alloying materials were added. A Bessemer converter could treat a heat of 5 to 30 tons at a time and they were usually operated in pairs, one being blown while another was being filled or tapped. Before the Bessemer process, Western Europe and the United States relied on the process to reduce the carbon content of white cast iron. It was possible to make low-quality puddled steel, but the process was difficult to control, high-quality steel was made by the reverse process of adding carbon to carbon-free wrought iron, usually imported from Sweden. The manufacturing process, called the process, consisted of heating bars of wrought iron together with charcoal for periods of up to a week in a long stone box. The blister steel was put in a crucible with wrought iron and melted, up to 3 tons of expensive coke was burnt for each ton of steel produced. Such steel when rolled into bars was sold at £50 to £60 a long ton, the most difficult and work-intensive part of the process, however, was the production of wrought iron done in finery forges in Sweden
