	John Ericsson - Wikipedia, the free encyclopedia
		John's and Nils's father Olof Ericsson who worked as the supervisor for a mine in Värmland had lost money in speculations and had to move his family from Värmland to Forsvik in 1810.
		Ericsson then proceeded to invent the "hot air engine" in 1852 which used hot air instead of steam as a propellant, probably inspired by his earlier attempts of fume heat engines in Sweden.
		Ericsson presented drawings of the USS Monitor a totally unique and novel design of armoured ships, which after much controversy was eventually built and finished on March 6, 1862.

		John's and Nils's father Olof Ericsson who worked as the supervisor for a mine in Wermelandia had lost money in speculations and had to move his family from Wermelandia to Forsvik in 1810.
		As a result, Ericsson moved to New York in 1839, and soon his propeller was installed in the newly constructed frigate SS Princeton, finished in 1843.
		Already on September 26 1854 Ericsson presented Napoleon III of France with drawings of iron-clad armoured battle ships with a dome-shaped gun tower, and even though the French king praised this invention, he did nothing to bring it to practical application.

	Seeing The Light - John Ericssson - Maritime design genius
		John Ericsson was born in Vermland, Sweden, and immigrated to England in 1826 with a working model of an engine design, which he called his Flame Engine.
		Ericsson was not deterred by the failure of the Caloric engine powered ship and continued to work on improving his Caloric engine concept, and was awarded patents for a number of improvements during the years 1855-1858.
		The Ericsson continued to work the Great Lakes until late 1963, when she was offered-up for use as a maritime museum in Toronto, and then moved to Hamilton.

		John Ericsson was born in the province of Vermland, Sweden, on July 31, 1803.
		While serving in the army, Ericsson became interested in steam engines and developed the theory for his caloric engine, which operated on the principle that air heated to very high temperature could be used to drive engines.
		Ericsson developed an animosity for the United States Navy that was to last for nearly 20 years.

		In 1862 the American academy of arts and sciences awarded the gold and silver Rumford medals to Ericsson " for his improvements in the management of heat, particularly as shown in his caloric engine of 1858." This was the second bestowal of the premium in the United States.
		In 1836 Ericsson invented and patented the screw propeller, which revolutionized navigation, and in 1837 built a steam vessel having twin screw propellers, which on trial towed the American packetship "Toronto" at the rate of five miles an hour on the River Thames.
		Subsequently the admiralty barge, bearing the lords of the admiralty, was towed at a rapid rate, but the endeavor to convince them of the practicability of the new device was futile, since they thought that, as the power must be applied at the stern, the vessel would not steer.

		After the Civil War, Ericsson turned his attention to the vulnerability of armored ships and revived his earlier idea of a system of submarine attack using submerged lighter weight torpedo boats which featured speed and guided torpedoes as countermeasures to the impregnability of the ironclad ships.
		Letters to editors of scientific and naval journals describing Ericsson's designs and often responding to critiques made by other scientists and naval officers are interspersed throughout the correspondence.

		At the age of 12 Ericsson became cadet of engineers, and at 17 entered the Swedish army.
		In 1836 Ericsson invented and patented the screw propeller, and in 1839 he came to the United States where, in 1841, he designed for the government the screw-propelled war ship "Princeton." This was the pioneer screw war ship.
		It carried a 12-inch wrought-iron gun, designed by Ericsson, and a wrought-iron gun carriage, which absorbed the recoil without breaking.

		John Ericsson had "been at odds" with the United States Navy since 1844 as a result of a cannon exploding on board of his ship, the U.S.S. Princeton.
		Ericsson had originally submitted his design for a "cupola battery" to Emperor Napoleon III during the Franco-Russian War hoping to aid in the defeat of his native country's "hereditary foe." His offer was declined.
		Ericsson responded with the details of material delays and navy intervention into his project and how both were beyond his control.

		He was the second son of Olaf Ericsson, an inspector of mines, who died in 1818.
		Showing from his earliest years a strong mechanical bent, young Ericsson, at the age of twelve, was employed as a draughtsman by the Swedish Canal Company.
		In 1836 he took out a patent for a screw-propeller, and though the priority of his invention could not be maintained, he was afterwards awarded a one-fifth share of the £20,000 given by the Admiralty for it.

		John Ericsson had in the meantime already devised what he regarded as a technological solution to at least numerical naval superiority.
		Ericsson’s proposal was even mentioned by name; and the “10 vessels” are in fact his own—the future Passaic-class; six to be completed (it was then hoped) within six months.
		Ericsson’s arguments for maximum concentration of weight, armour protection and firepower were better realized in the single turret of even thicker armour protection and ever greater guns than multiple turrets weakly protecting weaker armaments by comparison.

	John Ericsson
		John Ericsson (born July 31, 1803 in Långbanshyttan[?], Värmland, Sweden - died 1889 in USA) was a Swedish inventor and mechanical engineer, as was his brother, Nils Ericson.
		However Ericsson was awarded the Rumford medal[?] for this achievement.
		When the American Civil War broke out, the Southern states quickly armoured some of its battleships with iron, leading the congress to address this issue in August 1861 and recommend that such ships be built for the Northern army.

		Ericsson also reasoned that larger port-holes would increase the chances of stray shot or shell finding their way into the turret, with obvious disastrous consequences.
		A controversy ensued as Ericsson and his principal assistant, U.S. Navy Chief Engineer Alban C. Stimers, worked on a muzzle-ring and “smoke-box” which would allow the thicker 15-inch Dahlgren to be fired within the turret, without incapacitating the gun crews from concussion or smoke.
		The 15-inch specimen was to tactfully remind Ericsson of his positive contributions to the Union war effort despite all the mishaps, and encourage him further.

		John Ericsson of New York, whose name, during the late Rebellion, became a household word with the American people, by his valuable contributions of engineering skill, was born in the Province of Wermeland, Sweden, in 1803.
		Ericsson came to the United States, and was employed under the direction of the Navy Department in the construction of the United State ship-of-war, "Princeton," which was the first steamship ever built with the propelling machinery under the water-line and out of the reach of shot.
		Ericsson's list of inventions are so numerous that if set forth in detail they would of themselves fill up a volume.

		John Ericsson, one of the 19th Century's most creative engineers and inventors, was born on 31 July 1803 in Sweden.
		Ericsson left the Army in 1826 and moved to England, where he pursued a variety of engineering projects, among them the use of screw propellers on ships, the development of extraordinarly large guns and the creation of engines driven by hot air instead of steam.
		The outbreak of the American Civil War brought John Ericsson back into formal contact with the Navy, when he designed and produced USS Monitor, a revolutionary armored ship carrying her guns in a rotating turret.
