John Ericsson
John Ericsson (born Johan Ericsson; July 31, 1803 – March 8, 1889) was a Swedish-American engineer and inventor. He was active in England and the United States. Ericsson collaborated on the design of the railroad steam locomotive Novelty (locomotive), ''Novelty'', which competed in the Rainhill Trials on the Liverpool and Manchester Railway, which were won by inventor George Stephenson's (1781–1848), Stephenson's Rocket, ''Rocket''. Later in North America, he designed the United States Navy's first screw-propelled steam-frigate , in partnership with Captain (later Commodore) Robert F. Stockton (1795–1866) of the United States Navy, U.S. Navy, who unjustly blamed him for a USS_Princeton_(1843)#1844_Peacemaker_accident, fatal accident on the new vessel in 1844. A new partnership with Cornelius H. DeLamater (1821–1889), of the DeLamater Iron Works in New York City resulted in the first armoured ironclad warship equipped with a rotating gun turret, , which dramatically saved ...

Långban
Långban is a mining area in Värmland in Sweden. It belongs to Filipstad Municipality, with the nearest city being Filipstad, 21 km south. It was systematically mined through 1711–1972, but has traces from the 15th century. It is the birthplace of Swedish-American inventor John Ericsson and his brother Nils Ericson. It has been described as one of the most mineral-rich places in the world. The first discovery of native metal, native lead was in the Långban District in the late nineteenth century. Over 270 different minerals have been identified in the area and more than 60 of these have Långban as Type locality (geology), type locality. Most mining was done for iron ore and manganese ore, but in total, 300 minerals have been found. After 1950, only Dolomite (mineral), dolomite was extracted.

Stephenson's Rocket
Stephenson's ''Rocket'' is an early steam locomotive of 0-2-2 wheel arrangement. It was built for and won the Rainhill Trials of the Liverpool and Manchester Railway (L&MR), held in October 1829 to show that improved locomotives would be more efficient than stationary steam engines. ''Rocket'' was designed and built by Robert Stephenson in 1829, and built at the Forth Street Works of his company in Newcastle upon Tyne. Though ''Rocket'' was not the first steam locomotive, it was the first to bring together several innovations that produced the most advanced locomotive of its day. It is the most famous example of an evolving design of locomotives by Stephenson, and became the template for most steam engines in the following 150 years. The locomotive was displayed in the Science Museum in London until 2018, after which it was briefly exhibited at sites around the UK, ultimately at National Railway Museum in York. Since 2023, it has been based at the Locomotion Museum in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chesapeake Bay
The Chesapeake Bay ( ) is the largest estuary in the United States. The bay is located in the Mid-Atlantic (United States), Mid-Atlantic region and is primarily separated from the Atlantic Ocean by the Delmarva Peninsula, including parts of the Eastern Shore of Maryland, the Eastern Shore of Virginia, and the state of Delaware. The mouth of the bay at its southern point is located between Cape Henry and Cape Charles (headland), Cape Charles. With its northern portion in Maryland and the southern part in Virginia, the Chesapeake Bay is a very important feature for the ecology and economy of those two states, as well as others surrounding within its watershed. More than 150 major rivers and streams flow into the bay's drainage basin, which covers parts of six states (New York (state), New York, Pennsylvania, Delaware, Maryland, Virginia, and West Virginia) and all of Washington, D.C. The bay is approximately long from its northern headwaters in the Susquehanna River to its outlet i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Hampton Roads
The Battle of Hampton Roads, also referred to as the Battle of the ''Monitor'' and ''Merrimack'' or the Battle of Ironclads, was a naval battle during the American Civil War. The battle was fought over two days, March 8 and 9, 1862, in Hampton Roads, a roadstead in Virginia where the Elizabeth River (Virginia), Elizabeth and Nansemond River, Nansemond rivers meet the James River just before it flows into Chesapeake Bay by the city of Norfolk, Virginia, Norfolk. The battle was a part of the effort of the Confederate States of America, Confederacy to break the United States Navy, Union blockade, which had cut off Virginia's largest cities and major industrial centers, Norfolk and Richmond, Virginia, Richmond, from international trade.Musicant 1995, pp. 134–178; Anderson 1962, pp. 71–77; Tucker 2006, p. 151. At least one historian has argued that, rather than trying to break the blockade, the Confederacy was simply trying to take complete control of Hampton Roads in order to pro ...

Confederate States Navy
The Confederate States Navy (CSN) was the Navy, naval branch of the Confederate States Armed Forces, established by an act of the Confederate States Congress on February 21, 1861. It was responsible for Confederate naval operations during the American Civil War against the United States's Union Navy. The three major tasks of the Confederate States Navy during its existence were the protection of Confederate harbors and coastlines from outside invasion, making the war costly for the United States by attacking its merchant ships worldwide, and Blockade runners of the American Civil War, running the Union blockade, U.S. blockade by drawing off Union ships in pursuit of Confederate commerce raiders and warships. It was ineffective in these tasks, as the coastal blockade by the United States Navy reduced trade by the South to 5 percent of its pre-war levels. Additionally, the control of inland rivers and coastal navigation by the US Navy forced the south to overload its limited railroa ...

Gun Turret
A gun turret (or simply turret) is a mounting platform from which weapons can be fired that affords protection, visibility and ability to turn and aim. A modern gun turret is generally a rotatable weapon mount that houses the crew or mechanism of a projectile-firing weapon and at the same time lets the weapon be aimed and fired in some degree of azimuth and elevation (cone of fire). Description Rotating gun turrets protect the weapon and its crew as they rotate. When this meaning of the word "turret" started being used at the beginning of the 1860s, turrets were normally cylindrical. Barbettes were an alternative to turrets; with a barbette the protection was fixed, and the weapon and crew were on a rotating platform inside the barbette. In the 1890s, armoured hoods (also known as "gun houses") were added to barbettes; these rotated with the platform (hence the term "hooded barbette"). By the early 20th century, these hoods were known as turrets. Modern warships have gun-m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ironclad Warship
An ironclad was a steam-propelled warship protected by steel or iron armor constructed from 1859 to the early 1890s. The ironclad was developed as a result of the vulnerability of wooden warships to explosive or incendiary shells. The first ironclad battleship, , was launched by the French Navy in November 1859, narrowly preempting the British Royal Navy. However, Britain built the first completely iron-hulled warships. Ironclads were first used in warfare in 1862 during the American Civil War, when they operated against wooden ships, and against each other at the Battle of Hampton Roads in Virginia. Their performance demonstrated that the ironclad had replaced the unarmored ship of the line as the most powerful warship afloat. Ironclad gunboats became very successful in the American Civil War. Ironclads were designed for several uses, including as high-seas battleships, long-range cruisers, and coastal defense ships. Rapid development of warship design in the late 19th ...

USS Princeton (1843)
USS ''Princeton'' was a screw steam warship of the United States Navy. Commanded by Captain Robert F. Stockton, ''Princeton'' was launched on September 5, 1843. On February 28, 1844, during a Potomac River pleasure cruise for dignitaries, one gun exploded, killing six people, including Secretary of State Abel P. Upshur and Secretary of the Navy Thomas Walker Gilmer, and injuring others, including a United States Senator and Captain Stockton. The disaster on board the ''Princeton'' killed more top U.S. government officials in one day than any other tragedy in American history. President John Tyler, who was aboard but below decks, was not injured. The ship's reputation in the Navy never recovered. Early history ''Princeton'' was laid down on October 20, 1842, at the Philadelphia Navy Yard as a corvette. The designer of the ship and main supervisor of construction was the Swedish inventor John Ericsson, who later designed . The construction was partly supervised by Captain S ...
