Facts:

The Bessemer process revolutionized steel production by drastically lowering costs and increasing production volume. This made steel a more accessible material for diverse industrial applications.
Henry Bessemer, a British inventor, is credited with the development of the Bessemer process. However, his claim to sole invention was contested by several others, leading to a complex legal and historical debate.
William Kelly, an American ironmaster, also developed a process for refining iron using air blasts. However, it’s debated whether Kelly’s process aimed at producing steel or simply refining iron.
Joseph Martien, an American engineer, claimed priority in using air blasts to decarbonize molten iron. He conducted his experiments at the Ebbw Vale Iron Works in South Wales.
Robert Mushet, a Scottish metallurgist, claimed to have resolved a critical flaw in the Bessemer process by introducing manganese. He argued that the addition of manganese eliminated harmful impurities and improved the quality of the steel.
The Ebbw Vale Iron Works, one of the largest steel producers in South Wales, held patents related to Martien and Mushet’s inventions. The company actively sought to challenge Bessemer’s patent claims, potentially using these patents as bargaining chips.
The Ebbw Vale Iron Works also acquired the rights to the Uchatius process, a rival steel-making method. This indicates their desire to find alternative solutions to Bessemer’s process.
The Crimean War (1854-1856) stimulated interest in ordnance and armor, prompting Bessemer to explore new methods for steel production. The need for stronger materials for weapons and armor drove his research and ultimately led to the development of the Bessemer process.
The Civil War in the United States (1861-1865) also contributed to the growth of the steel industry. The demand for munitions and other war materials spurred the development and adoption of new steel-making technologies, including the Bessemer process.
The development of the Bessemer process involved a series of complex chemical reactions. The blowing of air through molten cast iron introduces oxygen, which reacts with the carbon and other impurities in the metal, leading to a reduction in carbon content and an increase in temperature.
The use of manganese was a crucial innovation in the Bessemer process. It helped to remove oxygen from the steel and improve its quality and durability.
The Bessemer process involved the use of a vessel known as a “converter”. This vessel was designed to hold the molten cast iron and allow for the controlled introduction of air.
The Bessemer process initially faced challenges in producing consistent quality steel. The presence of impurities such as sulfur and phosphorus in the pig iron could lead to inconsistent results.
The first successful application of the Bessemer process was achieved in Sweden. G. F. Goransson, a Swedish ironmaster, used Bessemer equipment to produce high-quality steel, demonstrating the process’s potential.
The Bessemer process led to the production of various types of steel, each with unique properties. The carbon content of the steel could be carefully controlled to achieve desired qualities, such as hardness, ductility, and tensile strength.
The Bessemer process had a significant impact on the development of new steel products. It made steel more affordable and available for a wider range of applications, including railroad tracks, bridges, and machinery.
The Bessemer process was eventually replaced by more advanced steel-making methods, such as the open-hearth process. However, its lasting legacy lies in its pioneering role in making steel a more affordable and accessible material for modern industrial society.
The patent system played a vital role in promoting innovation and protecting intellectual property. However, it also created challenges in resolving disputes over invention priority, as evidenced by the Bessemer controversy.
The success of the Bessemer process was not solely due to the efforts of Henry Bessemer. It involved the contributions of many individuals, including Kelly, Martien, and Mushet, even though they were often in conflict over who deserved credit for the innovation.
The Bessemer process marked a significant shift in the global steel industry. It established the United States as a dominant force in steel production, laying the groundwork for the country’s industrial expansion.

Statistics:

From 1870 to 1907, Bessemer steel production accounted for at least 50% of US steel production. This highlights the significant impact of the Bessemer process on the American steel industry.
Between 1880 and 1895, 80% of all steel produced in the United States was Bessemer steel. This further emphasizes the dominance of the Bessemer process in the US steel market during this period.
Mushet patented the use of manganese in steel making in 1856. He argued that adding manganese to the steel eliminated impurities and improved its quality.
The Ebbw Vale Iron Works offered Bessemer £50,000 for his patents in 1856. Bessemer refused this offer, likely due to his belief in the process’s potential and his desire to retain control over its development.
Ebbw Vale spent £7,000 attempting to implement Martien’s process. This demonstrates the company’s investment in finding alternative steel-making methods to rival Bessemer’s.
The Ebbw Vale Iron Works bought the British rights to the Uchatius process in 1856 for £2,000. This indicates their willingness to explore various options in their quest for a commercially viable steel-making process.
The Ebbw Vale Iron Works eventually paid Bessemer £30,000 for the rights to Martien and Parry’s patents. This signifies the company’s shift in strategy and their recognition of the Bessemer process’s dominance.
Mushet claimed to have made a 750-pound steel rail using his process. However, the same rail was later presented as an example of Uchatius steel, raising questions about Mushet’s claims.
Mushet received a £300 annual allowance from Bessemer. This suggests a complex relationship between the two men, perhaps influenced by the pressures of the steel industry and the media at the time.
Bessemer’s American patent, granted in 1856, was deemed worthless due to Kelly’s priority claim. This demonstrates the challenges faced by inventors in securing patent rights and the importance of timely patent application.
Kelly’s patent extension application was approved in 1871. This suggests the ongoing value of his invention and the recognition of his contributions to the steel industry.
Bessemer’s application for a patent extension in 1870 was denied due to the expiration of his British patent. This highlights the limitations of patent protection and the differences between national patent laws.
The Wyandotte steel plant in Detroit, built without a Bessemer license, used Kelly’s process. This exemplifies the challenges and contradictions associated with patent enforcement and the emergence of unlicensed competition.
The first successful Bessemer steel plant in the United States was built in 1864. This marked a significant milestone in the adoption of the Bessemer process and its impact on the US steel industry.
The Jackson Brothers, Bessemer’s French partners, trained L. M. Hart in Bessemer operations. Hart’s arrival in the United States in 1864 likely contributed to the successful implementation of the Bessemer process at the Wyandotte plant.
Kelly’s patent proved useful as a bargaining tool in negotiations with the Bessemer group. This illustrates how patent rights could be used strategically in business transactions and competition.
