HENRY See also:BESSEMER (1813-1898)
, See also:English engineer, was See also:born on the 19th of See also:January 1813, at Charlton, in See also:Hertfordshire
.
Throughout his See also:life he was a prolific inventor, but his name is chiefly known in connexion with the See also:Bessemer See also:process for the manufacture of See also:steel, by which it has been rendered famous throughout the civilized See also:world
.
Though this process is now largely supplemented, and even displaced, by various rivals, at the See also:- TIME (0. Eng. Lima, cf. Icel. timi, Swed. timme, hour, Dan. time; from the root also seen in " tide," properly the time of between the flow and ebb of the sea, cf. O. Eng. getidan, to happen, " even-tide," &c.; it is not directly related to Lat. tempus)

time it was brought out it was of enormous See also:industrial importance, since it effected a See also:great cheapening in the See also:price of steel, and led to that material being widely substituted for others which were inferior in almost every respect but that of cost
.
Bessemer's See also:attention was See also:drawn to the problem of steel manufacture in the course of an See also:attempt to improve the construction of guns
.
Coming to the conclusion that if any advance was to be made in See also:artillery better See also:- METAL
- METAL (through Fr. from Lat. metallum, mine, quarry, adapted from Gr. µATaXAov, in the same sense, probably connected with ,ueraAAdv, to search after, explore, µeTa, after, aAAos, other)
metal must be available, he established a small ironworks in St Pancras, and began a See also:series of experiments
.
These he carried on for two years before he evolved the essential See also:idea of his process, which is the decarbonization of See also:cast See also:iron by forcing a blast of See also:air through the See also:mass of metal when in the molten See also:condition
.
The first public announcement of the process was made at the See also:Cheltenham See also:- MEETING (from " to meet," to come together, assemble, 0. Eng. metals ; cf. Du. moeten, Swed. mota, Goth. gamotjan, &c., derivatives of the Teut. word for a meeting, seen in O. Eng. Wit, moot, an assembly of the people; cf. witanagemot)
meeting of the See also:British Association in 1856, and immediately attracted considerable See also:notice
.
Many metallurgists were sceptical on theoretical grounds about his results, and only became convinced when they saw that his process was really able to convert melted cast iron into malleable iron in a perfectly fluid See also:state
.
But though five firms applied without delay for licences to See also:work under his See also:patents, success did not at once attend his efforts; indeed, after several ironmasters had put the process to See also:practical trial and failed to get See also:good results, it was in danger of being thrust aside and entirely forgotten
.
Its author, however, instead of being discouraged by this lack of success, continued his experiments, and in two years was able to turn out a product, the quality of which was not inferior to that yielded by the older methods
.
But when he now tried to induce makers to take up his improved See also:system, he met with See also:general rebuffs, and finally was driven to undertake the exploitation of the process himself
.
To this end he erected steelworks in See also:Sheffield, on ground See also:purchased with the help of See also:friends, and began to manufacture steel
.
At first the output was insignificant, but gradually the magnitude of the operations was enlarged until the competition became effective, and steel traders generally became aware that the See also:firm of See also:- HENRY

Henry Bessemer & Co. was underselling them to the extent of £20 a ton
.
This See also:argument to the See also:pocket quickly had its effect, and licences were applied for in such See also:numbers that, in royalties for the use of his process, Bessemer received a sum in all considerably exceeding a million See also:sterling
.
Of course, patents of such obvious value did not See also:- ESCAPE (in mid. Eng. eschape or escape, from the O. Fr. eschapper, modern echapper, and escaper, low Lat. escapium, from ex, out of, and cappa, cape, cloak; cf. for the sense development the Gr. iichueoOat, literally to put off one's clothes, hence to sli
escape See also:criticism, and invalidity was freely urged against them on various grounds
.
But Bessemer was fortunate enough to maintain them intact without litigation, though he found it advisable to buy up the rights of one patentee, while in another See also:case he was freed from anxiety by the patent being allowed to See also:lapse in 1859 through non-See also:payment of fees
.
At the outset he had found great difficulty in making steel by his process—in his first licences to the See also:trade iron alone was mentioned
.
Experiments he made with See also:South See also:Wales iron were failures because the product was devoid of malleability; Mr Goransson, a See also:Swedish ironmaster, using the purer See also:charcoal See also:pig iron of that See also:country, was the first to make good steel by the process, and even he was successful only after many attempts
.
His results prompted Bessemer to try the purer iron obtained from See also:Cumberland See also:haematite, but even with this he did not meet with much success, until See also:Robert Mushet showed that the addition of a certain quantity of spiegeleisen had the effect of removing the difficulties
.
Whether or not Mushet's patents could have been sustained, the value of his See also:procedure was shown by its general See also:adoption in See also:conjunction with the Bessemer method of See also:conversion
.
At the same time it is only See also:fair to say that whatever may have been the conveniences of Mushet's See also:plan, it was not absolutely essential; this Bessemer proved in 1865, by exhibiting a series of samples of steel made by his own process alone
.
The pecuniary rewards of Bessemer's great invention came to him with See also:comparative quickness; but it was not till 1879 that the Royal Society admitted him as a See also:fellow and the See also:government honoured him with a See also:knighthood
.

Among Bessemer's numerous other inventions, not one of which attained a tithe of the success or importance of the steel process, were movable See also:dies for embossed stamps, a See also:gold paint, See also:sugar machinery, and a See also:ship which was to See also:save her passengers from the miseries of mal de mer
.
This last had her See also:saloon mounted in such a way as to be See also:free to See also:swing relatively to the See also:boat herself, and the idea was that this saloon should always be maintained steady and level, no See also:matter how rough the See also:sea
.
For this purpose See also:hydraulic mechanism of Bessemer's See also:design was arranged under the See also:control of an attendant, whose See also:duty it was to keep See also:watch on a spirit-level, and counteract by proper manipulation of the apparatus any deviation from the See also:horizontal that might See also:manifest itself on the See also:floor of the saloon owing to the See also:rolling of the See also:vessel
.
A boat, called the " Bessemer," was built on this plan in 1875 and put on the See also:cross-Channel service to See also:Calais, but the mechanism of the swinging saloon was not found effective in practice and was ultimately removed
.
An Autobiography was published in 1905
