ERICSSQN, See also:JOHN (1803-1889); See also:Swedish-See also:American See also:naval engineer, was See also:born at Langbanshyttan, Wermland, See also:Sweden, on the 31st of See also:July 1803. He was the second son of See also:Olaf Ericsson, an inspector of mines, who died in 1818. Showing from his earliest years a strong See also:mechanical See also:bent, See also:young Ericsson, at the See also:age of twelve, was employed as a draughtsman by the Swedish See also:Canal See also:Company. From 182o to 1827 he served in the See also:army, where his See also:drawing and military maps attracted the See also:attention of the See also:king, and he soon attained the See also:rank of See also:captain. In 1826 he went to See also:London, at first on leave of See also:absence from his See also:regiment, and in See also:partnership with John Braithwaite constructed the " Novelty," a See also:locomotive See also:engine for the See also:Liverpool & See also:Manchester railway competition at Rainhill in 1829, when the See also:prize, however, was won by See also:Stephenson's " See also:Rocket." The number of Ericsson's inventions at this See also:period was very See also:great. Among other things he worked out a See also:plan for marine engines placed entirely below the See also:water-See also:line. Such engines were made for the " Victory," for Captain (afterwards See also:Sir) John See also:Ross's voyage to the See also:Arctic regions in 1829, but they did not prove satisfactory. In 1833 his caloric engine was made public. In 1836 he took out a patent for a See also:screw-propeller, and though the priority of his invention could not be maintained, he was afterwards awarded a one-fifth See also:share of the £20;000 given by the See also:Admiralty for it. At this See also:time Captain See also:Stockton, of the See also:United States See also:navy, gave an See also:order for a small See also:iron See also:vessel to be built by See also:Laird of See also:Birkenhead, and to be fitted by Ericsson with engines and screw. This vessel reached New See also:York in May 1839. A few months later Ericsson followed his steamer to New York, and there he resided for the See also:rest of his See also:life, establishing himself as an engineer and a builder of iron See also:ships.

In 1848 he was naturalized as a See also:

citizen of the United States. He had many difficulties to contend with, and it was only by slow degrees that he established his fame and won his way to competence. At his See also:death he seems to have been See also:worth about £5o,000. The See also:provision of defensive See also:armour for ships of See also:war had See also:long occupied his attention, and he had constructed plans and a See also:model of a vessel lying See also:low in the water, carrying one heavy See also:gun in a circular See also:turret mounted on a turn-table. In 1854 he sent his plans to the See also:emperor of the See also:French. See also:Louis See also:Napoleon, however, acting probably on the See also:advice of See also:Dupuy de Lome, declined to use them. The American See also:Civil War, and the See also:report that the Confederates were converting the " See also:Merrimac " into an ironclad, caused the navy See also:department to invite proposals for the construction of armoured ships. Among others, Ericsson replied, and as it was thought that his See also:design might be serviceable in inland See also:waters, the first armoured turret See also:ship, the See also:Monitor," was ordered; she was launched on the 3oth of See also:January 1862, and on the 9th of See also:March she fought the celebrated See also:action with the Confederate See also:ram " Merrimac." The See also:peculiar circumstances in which she was built, the great importance of the See also:battle, and the decisive nature of the result gave the " Monitor " an exaggerated reputation, which further experience did not confirm. In later years Ericsson devoted himself to the study of torpedoes and See also:sun See also:motors. He published See also:Solar Investigations (New York, 1875) and Contributions to the Centennial See also:Exhibition (New York, 1877). He died in New York on the 8th of March 1889, and in the following See also:year, on the See also:request of the Swedish See also:government, his See also:body was sent to See also:Stockholm and thence into Wermland, where, at Filipstad, it was' buried on the 15th of See also:September. A Life of Ericsson by See also:William See also:Conant See also:Church was published in New York in 1890 and in London in 1893.
