Bessemer licensed the patent for his process to five Ironmasters, but from the outset, the companies had great difficulty producing good quality steel.

Television station WDBB ( channel 17 ) is licensed to Bessemer, but it actually broadcasts from studios in Birmingham, simulcasting with WTTO ( channel 21 ).

The Kelly patent and the Bessemer patent were licensed for steelmaking in Pennsylvania, at the Cambria Iron Works, starting in 1857.

Though the Bessemer process was licensed in 1856, nine years of detailed planning and project management were needed before the first steel was produced.

WDBB rebroadcasts WTTO's signal across the western part of the market and is licensed to the Birmingham suburb of Bessemer, but primarily serves the Tuscaloosa area.

WDBB then moved back to its original transmitter near Tuscaloosa, but remained licensed in Bessemer.

* October 17 – Henry Bessemer files his patent in the United Kingdom for the Bessemer process of steelmaking.

The process is named after its inventor, Henry Bessemer, who took out a patent on the process in 1855.

Starting in January 1855 he began working on a way to produce steel in the massive quantities required for artillery and by October he filed his first patent related to the Bessemer process.

Bessemer, however, acknowledged the efforts of Nasmyth by offering him a one-third share of the value of his patent.

Bessemer also obtained a patent in 1857 for the casting of metal between contrarotating rollers-a forerunner of today's continuous casting processes and remarkably, Bessemer's original idea has been implemented in the direct continuous casting of steel strip.

Bessemer, however, acknowledged the efforts of Nasmyth by offering him a one-third share of the value of his patent for the eponymous Bessemer process.

Another example is the Bessemer steel process — Bessemer sold a patent for his advanced steel making process and was sued by the purchasers who couldn't get it to work.

In the end Bessemer set up his own steel company because he knew how to do it, even though he could not convey it to his patent users.

Kelly applied for a patent after Bessemer patented the process, and was granted patent 17, 628 in 1857.

In 1871, the U. S. Patent Office granted Kelly a renewal of his patent for 7 years while rejecting applications for renewal by Bessemer and Robert Forester Mushet, who had also received patents for the process.

Kelly received only about 5 % of the patent royalties paid to Bessemer, and Bessemer's name was used for the process.

One of his two great innovations was in the cheap and efficient mass production of steel by adopting and adapting the Bessemer process for steel making.

The steel price dropped as a direct result, and Bessemer steel was rapidly adopted for railway lines and girders for buildings and bridges.

Carnegie's empire grew to include the J. Edgar Thomson Steel Works, ( named for John Edgar Thomson, Carnegie's former boss and president of the Pennsylvania Railroad ), Pittsburgh Bessemer Steel Works, the Lucy Furnaces, the Union Iron Mills, the Union Mill ( Wilson, Walker & County ), the Keystone Bridge Works, the Hartman Steel Works, the Frick Coke Company, and the Scotia ore mines.

Steel is often cited as the first of several new areas for industrial mass-production, which are said to characterise a " Second Industrial Revolution ", beginning around 1850, although a method for mass manufacture of steel was not invented until the 1860s, when Sir Henry Bessemer invented a new furnace which could convert wrought iron into steel in large quantities.

The 1880s saw the development of the Bessemer process for producing steel.

The Bessemer process was the first inexpensive industrial process for the mass-production of steel from molten pig iron.

The earliest Bessemer converters produced steel for £ 7 a long ton, although it initially sold for around £ 40 a ton.

According to this book at the time of the outbreak of the Crimean War many English industrialists and inventors became interested in military technology and Bessemer himself developed a method for grooving artillery projectiles so that they could spin without the use of rifling in the bore of the gun.

Bessemer's name is chiefly known in connection with the Bessemer process for the manufacture of steel.

The invention from which Henry Bessemer made his first fortune was a series of six steam-powered machines for making bronze powder.

Bessemer patented a method for making a continuous ribbon of plate glass in 1848, but it was not commercially successful ( see his autobiography, chapter 8 ).

Henry Bessemer worked on the problem of manufacturing cheap steel for the purposes of ordnance production from 1850 to 1855 when he patented his method.

This argument to the pocket quickly had its effect, and licences were applied for in such numbers that, in royalties for the use of his process, Bessemer received a sum in all considerably exceeding a million pounds sterling.

Bessemer decided to pay Mushet an annual pension of £ 300, a very considerable sum, which he paid for over 20 years ; possibly with a view to keeping the Mushets from legal action.

In 1858, Sir Henry Bessemer developed a process of steel making by blowing hot air through liquid pig iron to reduce the carbon content.

The Bessemer process was able to produce the first large scale manufacture of steel.

Once the Bessemer process began to gain widespread use, other alloys of steel began to follow, such as mangalloy, an alloy of steel and manganese, which exhibits extreme hardness and toughness.

As the forests of Britain and Europe continued to be over-harvested to supply the keels of larger wooden boats, and the Bessemer process ( patented in 1855 ) cheapened the cost of steel, steel ships and boats began to be more common.

He also invested in fluidized hotbed technologies ( notably the Bessemer process ) and acquired many mines in Germany and France.

With the invention of the Bessemer process in the mid-19th century, steel became an inexpensive mass-produced material.

* 1075 – the Song Chinese innovate a partial decarbonization method of repreated forging of cast iron under a cold blast that Hartwell and Needham consider to be a predecessor to the 18th century Bessemer process.

* Production of steel revolutionized by invention of the Bessemer process

The process using a basic refractory lining is known as the basic Bessemer process or Gilchrist-Thomas process after the discoverer Sidney Gilchrist Thomas.

Before the Bessemer process, Britain had no practical method of reducing the carbon content of pig iron.

The Bessemer process reduced the time needed to make steel of this quality to about half an hour while requiring only the coke needed to melt the pig iron initially.

On 24 August 1856 Bessemer first described the process to a meeting of the British Association in Cheltenham which he titled " The Manufacture of Iron Without Fuel.
