He had lost money in speculation and had to move his family to Forsvik in 1810. There he worked as a director of blastings during the excavation of the Swedish Göta Canal. The extraordinary skills of the two Ericsson brothers were discovered by Baltzar von Platen (1766–1829), the architect of Göta Canal. They were dubbed 'cadets of mechanics' of the Swedish Royal Navy, and engaged as trainees at the canal enterprise. At the age of fourteen, John was already working independently as a surveyor. His assistant had to carry a footstool for him to reach the instruments during

Notwithstanding the disappointment, he invented several other mechanisms instead based on

with ''Rocket''. Two further engines were built by Braithwaite and Ericsson, named '' William IV'' and ''Queen Adelaide'' after the new king and queen. These were generally larger and more robust than ''Novelty'' and differed in several details (for example it is thought that a different design of blower was used which was an 'Induced Draught' type, sucking the gases from the fire). The pair ran trials on the Liverpool and Manchester Railway but the railway declined to purchase the new designs. Their innovative steam fire engine proved an outstanding technical success by helping to quell the memorable Argyll Rooms fire on February 5, 1830 (where it worked for five hours when the other engines were frozen up),Burnett, Constance Buel (1960) ''Captain John Ericsson: Father of the Monitor'', Vanguard Press, New York, p. 107. but was met with resistance from London's established 'Fire Laddies' and municipal authorities. An engine Braithwaite and Ericsson constructed for Sir John Ross's 1829 Arctic expedition failed and was dumped on the shores of Prince Regent Inlet. At this stage of Ericsson's career the most successful and enduring of his inventions was the surface condenser, which allowed a steamer to recover fresh water for its boilers while at sea. His 'deep sea lead,' a pressure-activated fathometer was another minor, but enduring success. The commercial failure and development costs of some of the machines devised and built by Ericsson during this period put him into debtors' prison for an interval. At this time he also married 19-year-old Amelia Byam, a disastrous match that ended in the couple's separation until Amelia's death. He was elected as a member to the

located there. The ship took about three years to complete and was perhaps the most advanced warship of its time. In addition to steam-powered twin screw propellers, it was originally designed to mount a 12-inch muzzle-loading gun on a revolving pedestal. The gun had also been designed by Ericsson and used hoop construction to pre-tension the breech, adding to its strength and allowing safe use of a larger charge. Other innovations on the warship design included a collapsible smoke funnel and an improved recoil system for the artillery. The relations between Ericsson and Stockton had grown tense over time and, approaching the completion of the ship, Stockton began working to force Ericsson out of the shipbuilding project. Stockton carefully avoided letting outsiders know that Ericsson was the primary inventor. Stockton attempted to claim as much credit for himself as possible, even designing a second gun to be also mounted on the ''Princeton''. Unfortunately, because Stockton did not totally understand the design of the first gun (originally named "The Orator", renamed "The Oregon" by Stockton), the second gun was fatally flawed. When launched, the '' U.S.S. Princeton'' was an enormous success. On October 20, 1843, she won a speed trial against the huge passenger liner, paddle steamer , until then considered the fastest steamer afloat. Unfortunately, during a firing demonstration of Capt. Stockton's gun, the breech ruptured and exploded, killing visiting onboard observers of U.S. Secretary of State Abel P. Upshur and the

Stockton also refused to pay Ericsson, and by using his political connections, Stockton blocked the U.S. Navy bureaucracy from paying him.

to give his work to the Phoenix Foundry. There he met industrialist and iron / steel foundry owner Cornelius H. DeLamater (1821–1889), and soon a mutual attachment developed between the two. Rarely thereafter did Ericsson or DeLamater enter upon a business venture without first consulting the other." Personally, their friendship never faltered, though strained by the pressures of business and Ericsson's quick temper, DeLamater called Ericsson "John" and Ericsson called DeLamater by his middle nickname "Harry", intimacies almost unknown in Ericsson's other relationships. In time, the DeLamater Iron Works, situated facing the

The first hot-air invention of Capt Ericsson was first introduced in the ship ''Ericsson'', built entirely by DeLamater. The DeLamater Iron Works also launched the first submarine boat, first self-propelled torpedo, and first torpedo boat. When DeLamater died on February 2, 1889, Ericsson could not be consoled. Ericsson's own death only one month later in March 1889, was not surprising to his close friends and acquaintances."


Hot air engine

Ericsson then proceeded to invent independently the caloric, or hot air, engine in the 1820s which used hot air, caloric in the scientific parlance of the day, instead of steam as a working fluid. A similar device had been patented earlier in 1816 by the Reverend Robert Stirling (1790-1878), whose technical priority of invention provides the usual term 'Stirling Engine' for the device. Ericsson's engine was not initially successful due to the differences in combustion temperatures between burning Swedish wood and firing of British coal. In spite of his setbacks, Ericsson was later awarded the Rumford Prize of the American Academy of Arts and Sciences in 1862 for his invention. In 1830, Ericsson patented his second engine, that can work either with steam, air or water. This rotative engine objective is to reduce the engine within more convenient limits without any corresponding loss of power. By 1833, Capt. Ericsson built his third engine, a hot air engine (or caloric engine) that is exhibited in London: "the engine will prove the most important mechanical invention ever conceived by the human mind, and one that will confer greater benefits on civilized life than any that has ever preceded it" (John O. Sargent). This engine included a regenerator that would inspire many other hot air engine inventors. The caloric ship, powered by the fourth Ericsson engine was built in 1852. A group of New York merchants and financiers headed by John B Kitching, Edward Dunham, President of the Corn Exchange Bank, and G.B. Lamar, president of the Bank of the Republic, backed the project and in April, 1852, the keel of the ship was laid at the yard of Perine, Patterson, and Stack in Williamsburgh. At about the same time the construction of the engine was commenced by Messrs Hogg and Delamater. Hull and machinery were built in the greatest possible secrecy, both Ericsson and his financial backers being convinced that their ship would revolutionize ocean transport by its economy and safety, and that competitors would if possible copy the design of at least the engine. On September 15, 1852, the ship was launched and in November the engine was turned over at the dock under its own power. It will be a failure. Smaller experimental engines based on the same patent design and built before the caloric ship will prove to be working efficiently. In his later years, the caloric engine would render Ericsson comfortably wealthy, as its boilerless design made it a much safer and more practical means of power for small industry than steam engines. Ericsson's incorporation of a 'regenerator' heat sink for his engine made it tremendously fuel-efficient. Apparently in the post Civil War era some time before or around 1882, from the publishing date, a ship was purchased by a Captain Charles L. Dingley called the ''Ericsson'' with a weight of 1,645 tons that was built by John Ericsson (Although the above section on John Ericsson's Friendship with Cornelius H. DeLamater says that the ship known as the ''Ericsson'' was built by the DeLamater Iron Works) to try out the hot air engine as a motive power in open ocean navigation. Decades later, in 1883 John Ericsson built a solar air engine of 1 HP. The leading feature of the sun motor is that of concentrating the radiant heat by means of a rectangular trough having a curved bottom lined on the inside with polished plates, so arranged that they reflect the sun's rays toward a cylindrical heater placed longitudinally above the trough. This heater, it is scarcely necessary to state, contains the acting medium, steam or air, employed to transfer the solar energy to the motor; the transfer being effected by means of cylinders provided' with pistons and valves resembling those of motive engines of the ordinary type. Practical engineers, as well as scientists, have demonstrated that solar energy cannot be rendered available for producing motive power, in consequence of the feebleness of solar radiation.

Despite controversy over the unique design, based on Swedish lumber rafts, the keel was eventually laid down in a New York shipyard and the experimental ironclad was launched on March 6, 1862.

, including additional twin turret versions, and contributed greatly to the further continued success of the blockade of Southern coasts and port cities with naval victory of the Union over the rebellious states. Despite their low draft and subsequent problems in navigating in high seas, plus frequent engine break-downs, many basic design elements of the ''Monitor'' class were copied in future warships by other designers and navies around the world. The rotating gun turret in particular is considered one of the greatest technological advances in naval history, still found on modern warships today.


Later designs

One of these designs earned Ericsson additional income after being converted to work as a methane gas engine.


Death and ensuing controversy

Ericsson died on March 8, 1889, the anniversary of the Battle of Hampton Roads, in which his ''Monitor'' famously played a central role. His wish to be buried in his native land sparked a series of articles in the ''
