Benjamin F. Isherwood
Benjamin Franklin Isherwood (October 6, 1822 – June 19, 1915) was an engineering officer in the United States Navy during the early days of steam-powered warships. He served as a ship's engineer during the Mexican–American War, and after the war did experimental work with steam propulsion. Rising to the rank of rear admiral, as Engineer-in-Chief of the Navy during the Civil War, he helped to found the Navy's Bureau of Steam Engineering. Career in civilian engineering Isherwood was born in New York City. He worked for the Utica and Schenectady Railroad and trained under William C. Young, one of the most prominent engineers of that period. Isherwood then worked on the Croton Aqueduct, followed by an engineering job on the Erie Canal. Designing and constructing lighthouses for the Treasury Department was Isherwood's last employment before joining the Navy. Early Naval career At the age of 22, Isherwood was appointed first assistant engineer in the Navy May 23, 1844, servin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Civil War
The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States. It was fought between the Union ("the North") and the Confederacy ("the South"), the latter formed by states that had seceded. The central cause of the war was the dispute over whether slavery would be permitted to expand into the western territories, leading to more slave states, or be prevented from doing so, which was widely believed would place slavery on a course of ultimate extinction. Decades of political controversy over slavery were brought to a head by the victory in the 1860 U.S. presidential election of Abraham Lincoln, who opposed slavery's expansion into the west. An initial seven southern slave states responded to Lincoln's victory by seceding from the United States and, in 1861, forming the Confederacy. The Confederacy seized U.S. forts and other federal assets within their borders. Led by Confederate President Jefferson Davis, ...

Frigate
A frigate () is a type of warship. In different eras, the roles and capabilities of ships classified as frigates have varied somewhat. The name frigate in the 17th to early 18th centuries was given to any full-rigged ship built for speed and maneuverability, intended to be used in scouting, escort and patrol roles. The term was applied loosely to ships varying greatly in design. In the second quarter of the 18th century, the 'true frigate' was developed in France. This type of vessel was characterised by possessing only one armed deck, with an unarmed deck below it used for berthing the crew. Late in the 19th century (British and French prototypes were constructed in 1858), armoured frigates were developed as powerful ironclad warships, the term frigate was used because of their single gun deck. Later developments in ironclad ships rendered the frigate designation obsolete and the term fell out of favour. During the Second World War the name 'frigate' was reintroduced to des ...

Library Of Congress
The Library of Congress (LOC) is the research library that officially serves the United States Congress and is the ''de facto'' national library of the United States. It is the oldest federal cultural institution in the country. The library is housed in three buildings on Capitol Hill in Washington, D.C.; it also maintains a conservation center in Culpeper, Virginia. The library's functions are overseen by the Librarian of Congress, and its buildings are maintained by the Architect of the Capitol. The Library of Congress is one of the largest libraries in the world. Its "collections are universal, not limited by subject, format, or national boundary, and include research materials from all parts of the world and in more than 470 languages." Congress moved to Washington, D.C., in 1800 after holding sessions for eleven years in the temporary national capitals in New York City and Philadelphia. In both cities, members of the U.S. Congress had access to the sizable collection ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cruiser
A cruiser is a type of warship. Modern cruisers are generally the largest ships in a fleet after aircraft carriers and amphibious assault ships, and can usually perform several roles. The term "cruiser", which has been in use for several hundred years, has changed its meaning over time. During the Age of Sail, the term ''cruising'' referred to certain kinds of missions—independent scouting, commerce protection, or raiding—fulfilled by frigates or sloops-of-war, which functioned as the ''cruising warships'' of a fleet. In the middle of the 19th century, ''cruiser'' came to be a classification of the ships intended for cruising distant waters, for commerce raiding, and for scouting for the battle fleet. Cruisers came in a wide variety of sizes, from the medium-sized protected cruiser to large armored cruisers that were nearly as big (although not as powerful or as well-armored) as a pre-dreadnought battleship. With the advent of the dreadnought battleship before World W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Propeller
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mare Island Navy Yard
The Mare Island Naval Shipyard (MINSY) was the first United States Navy base established on the Pacific Ocean. It is located northeast of San Francisco in Vallejo, California. The Napa River goes through the Mare Island Strait and separates the peninsula shipyard (Mare Island, California) from the main portion of the city of Vallejo. MINSY made a name for itself as the premier U.S. West Coast submarine port as well as serving as the controlling force in San Francisco Bay Area shipbuilding efforts during World War II. The base closed in 1996 and has gone through several redevelopment phases. It was registered as a California Historical Landmark in 1960, and parts of it were declared a National Historic Landmark District in 1975. Beginnings In September 1849, Lieutenant Commander William Pope McArthur was placed in command of the US survey schooner ''Ewing'', which had been brought around Cape Horn to the West Coast by Lieutenant Washington Allon Bartlett.

Gideon Welles
Gideon Welles (July 1, 1802 – February 11, 1878), nicknamed "Father Neptune", was the United States Secretary of the Navy from 1861 to 1869, a cabinet post he was awarded after supporting Abraham Lincoln in the 1860 election. Although opposed to the Union blockade of Southern ports, he duly carried out his part of the Anaconda Plan, largely sealing off the Confederate coastline and preventing the exchange of cotton for war supplies. This is viewed as a major cause of Union victory in the Civil War, and his achievement in expanding the Navy almost tenfold was widely praised. Welles was also instrumental in the Navy's creation of the Medal of Honor. Early political career Gideon Welles, the son of Samuel Welles and Ann Hale, was born on July 1, 1802, in Glastonbury, Connecticut. His father was a shipping merchant and fervent Jeffersonian; he was a member of the Convention, which formed the first state Connecticut Constitution in 1818 that abolished the colonial charter and offi ...

David Dixon Porter
David Dixon Porter (June 8, 1813 – February 13, 1891) was a United States Navy admiral and a member of one of the most distinguished families in the history of the U.S. Navy. Promoted as the second U.S. Navy officer ever to attain the rank of admiral, after his adoptive brother David G. Farragut, Porter helped improve the Navy as the Superintendent of the U.S. Naval Academy after significant service in the American Civil War. Porter began naval service as a midshipman at the age of 10 years under his father, Commodore David Porter, on the frigate . For the remainder of his life, he was associated with the sea.
