John Lenthall (shipbuilder)
John Lenthall (16 September 1807 – 11 April 1882) was an important American shipbuilder and naval architect. He was responsible for the construction and repair of United States Navy ships during the American Civil War (1861–1865), as well as in the years immediately before and after it. His career spanned the U.S. Navys transition from sail to steam propulsion and from wooden ships to ironclads, and in retirement he participated in early planning for an eventual steel navy. Early life John Lenthall was born in Washington, D.C., on 16 September 1807,Tucker, p. 348. the son of John Lenthall (1762–1808) and Mary King Lenthall (1780–1852). His British-born father was an architect who had emigrated to the United States in 1793 and from 1803 worked as Clerk of the Works and Principal Surveyor at the United States Capitol Building in Washington under Architect of the Capitol Benjamin Henry Latrobe, serving as the buildings construction superintendent. The senior John Lenthall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carpenter
Carpentry is a skilled trade and a craft in which the primary work performed is the cutting, shaping and installation of building materials during the construction of buildings, Shipbuilding, ships, timber bridges, concrete formwork, etc. Carpenters traditionally worked with natural wood and did rougher work such as framing, but today many other materials are also used and sometimes the finer trades of cabinetmaking and furniture building are considered carpentry. In the United States, 98.5% of carpenters are male, and it was the fourth most male-dominated occupation in the country in 1999. In 2006 in the United States, there were about 1.5 million carpentry positions. Carpenters are usually the first tradesmen on a job and the last to leave. Carpenters normally framed post-and-beam buildings until the end of the 19th century; now this old-fashioned carpentry is called timber framing. Carpenters learn this trade by being employed through an apprenticeship training—normally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship-of-the-line
A ship of the line was a type of naval warship constructed during the Age of Sail from the 17th century to the mid-19th century. The ship of the line was designed for the naval tactic known as the line of battle, which depended on the two columns of opposing warships maneuvering to volley fire with the cannons along their broadsides. In conflicts where opposing ships were both able to fire from their broadsides, the opponent with more cannons firingand therefore more firepowertypically had an advantage. Since these engagements were almost invariably won by the heaviest ships carrying more of the most powerful guns, the natural progression was to build sailing vessels that were the largest and most powerful of their time. From the end of the 1840s, the introduction of steam power brought less dependence on the wind in battle and led to the construction of screw-driven wooden-hulled ships of the line; a number of purely sail-powered ships were converted to this propulsion mechani ...

First-rate
In the rating system of the British Royal Navy used to categorise sailing warships, a first rate was the designation for the largest ships of the line. Originating in the Jacobean era with the designation of Ships Royal capable of carrying at least 400 men, the size and establishment of first-rates evolved over the following 250 years to eventually denote ships of the line carrying at least 80 guns across three gundecks. By the end of the eighteenth century, a first-rate carried no fewer than 100 guns and more than 850 crew, and had a measurement ( burthen) tonnage of some 2,000 tons. Origins The concept of a rating system for British naval vessels dates to the accession of James I of England, following which the fleet was formally divided into "great", "middling" and "lesser" craft. A 1618 commission of enquiry added a further designation of "Ships Royal" for the largest and most prestigious vessels in the fleet, each capable of carrying at least 400 men. The first Ships Roy ...

USS Decatur (1839)
USS ''Decatur'' was a sloop-of-war in the United States Navy during the mid-19th century. She was commissioned to protect American interests in the South Atlantic Ocean, including the interception of ships involved in the African slave trade. ''Decatur'' served in both the Mexican–American War and the American Civil War. The sloop-of-war was named in honor of Commodore Stephen Decatur (1779–1820), one of the United States Navy's greatest heroes and leaders of the first two decades of the 19th century. Launched in 1839 at the New York Navy Yard ''Decatur'', a large sloop of 566 tons, was built in 1838 and 1839 at New York Navy Yard. She was outfitted with heavy guns and manned by a crew of 150 officers and enlisted men. South Atlantic Ocean operations Commanded by Commander H. W. Ogden, she sailed from New York 16 March 1840 for duty with the Brazil Squadron, returning to Norfolk, Virginia 28 February 1843. Her second cruise, from 5 August 1843 to 3 January 1845 was ...

Commissioned Officer
An officer is a person who holds a position of authority as a member of an armed force or uniformed service. Broadly speaking, "officer" means a commissioned officer, a non-commissioned officer, or a warrant officer. However, absent contextual qualification, the term typically refers only to a force's ''commissioned officers'', the more senior members who derive their authority from a commission from the head of state. Numbers The proportion of officers varies greatly. Commissioned officers typically make up between an eighth and a fifth of modern armed forces personnel. In 2013, officers were the senior 17% of the British armed forces, and the senior 13.7% of the French armed forces. In 2012, officers made up about 18% of the German armed forces, and about 17.2% of the United States armed forces. Historically, however, armed forces have generally had much lower proportions of officers. During the First World War, fewer than 5% of British soldiers were officers (partly ...

Merchant Ship
A merchant ship, merchant vessel, trading vessel, or merchantman is a watercraft that transports cargo or carries passengers for hire. This is in contrast to pleasure craft, which are used for personal recreation, and naval ships, which are used for military purposes. They come in myriad sizes and shapes, from inflatable dive boats in Hawaii, to 5,000-passenger casino vessels on the Mississippi River, to tugboats plying New York Harbor, to oil tankers and container ships at major ports, to passenger-carrying submarines in the Caribbean. Many merchant ships operate under a "flag of convenience" from a country other than the home of the vessel's owners, such as Liberia and Panama, which have more favorable maritime laws than other countries. The Greek merchant marine is the largest in the world. Today, the Greek fleet accounts for some 16 per cent of the world's tonnage; this makes it currently the largest single international merchant fleet in the world, albeit not the la ...

Draftsman
A drafter (also draughtsman / draughtswoman in British and Commonwealth English, draftsman / draftswoman or drafting technician in American and Canadian English) is an engineering technician who makes detailed technical drawings or plans for machinery, buildings, electronics, infrastructure, sections, etc. Drafters use computer software and manual sketches to convert the designs, plans, and layouts of engineers and architects into a set of technical drawings. Drafters operate as the supporting developers and sketch engineering designs and drawings from preliminary design concepts. Overview In the past, drafters sat at drawing boards and used pencils, pens, compasses, protractors, triangles, and other drafting devices to prepare a drawing by hand. From the 1980s through 1990s, board drawings were going out of style as the newly developed computer-aided design (CAD) system was released and was able to produce technical drawings at a faster pace. Many modern drafters now use co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philadelphia, Pennsylvania
Philadelphia, often called Philly, is the largest city in the Commonwealth of Pennsylvania, the sixth-largest city in the U.S., the second-largest city in both the Northeast megalopolis and Mid-Atlantic regions after New York City. Since 1854, the city has been coextensive with Philadelphia County, the most populous county in Pennsylvania and the urban core of the Delaware Valley, the nation's seventh-largest and one of world's largest metropolitan regions, with 6.245 million residents . The city's population at the 2020 census was 1,603,797, and over 56 million people live within of Philadelphia. Philadelphia was founded in 1682 by William Penn, an English Quaker. The city served as capital of the Pennsylvania Colony during the British colonial era and went on to play a historic and vital role as the central meeting place for the nation's founding fathers whose plans and actions in Philadelphia ultimately inspired the American Revolution and the nation's inde ...

Philadelphia Navy Yard
The Philadelphia Naval Shipyard was an important naval shipyard of the United States for almost two centuries. Philadelphia's original navy yard, begun in 1776 on Front Street and Federal Street in what is now the Pennsport section of the city, was the first naval shipyard of the United States. It was replaced by a new, much larger yard developed around facilities begun in 1871 on League Island, at the confluence of the Delaware and Schuylkill rivers. The Navy Yard expansion stimulated the development over time of residential and businesses in South Philadelphia, where many shipyard workers lived. During World War II, some 40,000 workers operated on shifts around the clock to produce and repair ships at the yard for the war effort. The United States Navy ended most of its activities there in the 1990s, closing its base after recommendations by the Base Realignment and Closure commission. In 2000, the Philadelphia Industrial Development Corporation, on behalf of the city of Ph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Samuel Humphreys
Samuel Humphreys (23 November 1778 – 16 August 1846) was a noted American naval architect and shipbuilder in the early 19th century. He served the United States Navy as the Chief Constructor for the Navy from 1826 to 1846. Naval architect Samuel Humphreys supervised the construction of the frigate , which was laid down at Philadelphia, Pennsylvania, in 1798, and launched in 1799. He later constructed ships at the Philadelphia Navy Yard, and supervised the construction of the ship-of-the-line , the first ship to be laid down at the yard, in 1815. In 1824, Humphreys turned down a very lucrative offer from Emperor Alexander I of Russia to create a Russian navy, saying: "I do not know that I possess the merits attributed to me, but, be they great or small, I owe them all to the flag of my country." In 1826, Humpherys was elected a member of the American Philosophical Society. Humphreys was Chief Constructor for the Navy from 1826 to 1846. He designed Americas first ...
