Stories of Invention, Told by Inventors and their Friends

by Edward Everett Hale

"It is impossible to estimate the addition which these improvements have made to the physical power of the world. I have not the most recent figures, but look at this," said Uncle Fritz. And he gave to John to read from a Life of Sir Henry Bessemer:—

"Prior to this invention the entire production of cast steel in Great Britain was only about fifty thousand tons annually; and its average price, which ranged from £50 to £600, prohibited its use for many of the purposes to which it is now universally applied. After the invention, in the year 1877, the Bessemer steel produced in Great Britain alone amounted to 750,000 tons, or fifteen times the total of the former method of manufacture, while the selling price averaged only £10 per ton, and the coal consumed in producing it was less by 3,500,000 tons than would have been required in order to make the same quality of steel by the old, or Sheffield, process. The total reduction of cost is equal to about £30,000,000 sterling upon the quantity manufactured in England during the year."

The same book goes on to show that in other nations £20,000,000 worth of Bessemer steel was produced in the same year.

"You see," said Uncle Fritz, "that here is an addition to the real wealth of the world such as makes any average fairy story about diamonds and rubies rather cheap and contemptible.

"You will like Sir Henry Bessemer, Hester, because he was happily trained and had good chances when he was a boy. And you will be amused to see how his bright wife was brighter than all the internal-revenue people. She was so bright that she lost him the appointment which had enabled him to marry her. But I think he says somewhere, with a good deal of pride, that but for that misfortune, and the injustice which accompanied it, he should have probably never made his great inventions. It is one more piece of 'Partial evil,—universal good.'"

Then the children, with Uncle Fritz's aid, began picking out what they called the plums from the accounts he showed them of Sir Henry Bessemer's life.

BESSEMER'S FAMILY.

At the time of the great Revolution of 1792 there was employed in the French mint a man of great ingenuity, who had become a member of the French Academy of Sciences at the age of twenty-five. When Robespierre became Dictator of France, this scientific academician was transferred from the mint to the management of a public bakery, established for the purpose of supplying the populace of Paris with bread. In that position he soon became the object of revolutionary frenzy. One day a rumor was set afloat that the loaves supplied were light in weight; and, spreading like wildfire, it was made the occasion of a fearful tumult. The manager of the bakery was instantly seized and cast into prison. He succeeded in escaping, but it was at the peril of his life. Knowing the peril he was in, he lost no time in making his way to England; and he only succeeded in doing so by adroitly using some documents he possessed bearing the signature of the Dictator. Landing in England a ruined man, his talents soon proved a passport to success. He was appointed to a position in the English mint; and by the exercise of his ingenuity in other directions, he ere long acquired sufficient means to buy a small estate at Charlton, in Hertfordshire. Such, in brief, were the circumstances that led to the settlement there of Anthony Bessemer, the father of Sir Henry Bessemer. The latter may be said to have been born an inventor. His father was an inventor before him. After settling in England, his inventive ingenuity was displayed in making improvements in microscopes and in type-founding, and in the discovery of what his son has happily described as the true alchemy. The latter discovery, which he made about the beginning of the present century, was a source of considerable profit to him. It is generally known that when gold articles are made by the jewellers, there are various discolorations left on their surface by the process of manufacture; and in order to clear their surface, they are put into a solution of alum, salt, and saltpetre, which dissolves a large quantity of the copper that is used as an alloy. Anthony Bessemer discovered that this powerful acid not only dissolved the copper, but also dissolved a quantity of gold. He accordingly began to buy up this liquor; and as he was the only one who knew that it contained gold in solution, he had no difficulty in arranging for the purchase of it from all the manufacturers in London. From that liquor he succeeded in extracting gold in considerable quantities for many years. By some means that he kept secret (and the secret died with him), he deposited the particles of gold on the shavings of another metal, which, being afterwards melted, left the pure gold in small quantities. Thirty years afterward the Messrs. Elkington invented the electrotype process, which had the same effect. Anthony Bessemer was also eminently successful as a type-founder. When in France, before the Revolution of 1792, he cut a great many founts of type for Messrs. Firmin Didot, the celebrated French type-founders; and after his return to England he betook himself, as a diversion, to type-cutting for Mr. Henry Caslon, the celebrated English type-founder. He engraved an entire series, from pica to diamond,—a work which occupied several years. The success of these types led to the establishment of the firm of Bessemer and Catherwood as type-founders, carrying on business at Charlton. The great improvement which Anthony Bessemer introduced into the art of type-making was not so much in the engraving as in the composition of the metal. He discovered that an alloy of copper, tin, and bismuth was the most durable metal for type; and the working of this discovery was very successful in his hands. The secret of his success, however, he kept unknown to the trade. He knew that if it were suspected that the superiority of his type consisted in the composition of the metal, analysis would reveal it, and others would then be able to compete with him. So, to divert attention from the real cause, he pointed out to the trade that the shape of his type was different, as the angle at which all the lines were produced from the surface was more obtuse in his type than in those of other manufacturers, at the same time contending that his type would wear longer. Other manufacturers ridiculed this account of Bessemer's type, but experience showed that it lasted nearly twice as long as other type. The business flourished for a dozen years under his direction, and during that period the real cause of its success was kept a secret. The process has since been re-discovered and patented. Such were some of the inventive efforts of the father of one of the greatest inventors of the present age.

HENRY BESSEMER.

The youngest son of Anthony Bessemer, Henry, was born at Charlton, in Hertfordshire, in 1813. His boyhood was spent in his native village; and while receiving the rudiments of an ordinary education in the neighboring town of Hitchin, the leisure and retirement of rural life afforded ample time, though perhaps little inducement, for the display of the natural bent of his mind. Notwithstanding his scanty and imperfect mechanical appliances, his early years were devoted to the cultivation of his inventive faculties. His parents encouraged him in his youthful efforts.
