Joshua Lionel Cowen
Joshua Lionel Cowen (; August 25, 1877 – September 8, 1965) was an American electrical engineer and inventor. Cowen attended two different colleges but never obtained a degree. He had a mechanical inclination and was interested in the principals of electricity. He worked a lot with batteries, transformers, and electrical motors which led to inventions and innovations. His first patented invention for a photographer's flash igniter for flash photography developed into a detonator for exploding mines for the United States Navy. That resulted in a $12,000 () defense contract which gave him the money to go into the novelty business. He was the co-founder of a manufacturer of model railroads and toy trains called Lionel trains. When he first made the Lionel toy train it was intended to be used as an advertising gimmick to attract people to store windows to sell other products. By accident people were more interested in the self-running electric toy train than the products in the dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States

Cooper Union
The Cooper Union for the Advancement of Science and Art (Cooper Union) is a private college at Cooper Square in New York City. Peter Cooper founded the institution in 1859 after learning about the government-supported École Polytechnique in France. The school was built on a radical new model of American higher education based on Cooper's belief that an education "equal to the best technology schools established" should be accessible to those who qualify, independent of their race, religion, sex, wealth or social status, and should be "open and free to all." Cooper is considered to be one of the most prestigious colleges in the United States, with all three of its member schools consistently ranked among the highest in the country. The Cooper Union originally offered free courses to its admitted students, and when a four-year undergraduate program was established in 1902, the school granted each admitted student a full-tuition scholarship. Following its own financial crisi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Postwar Economic Boom
In Western usage, the phrase post-war era (or postwar era) usually refers to the time since the end of World War II. More broadly, a post-war period (or postwar period) is the interval immediately following the end of a war. A post-war period can become an interwar period or interbellum, when a war between the same parties resumes at a later date (such as the period between World War I and World War II). By contrast, a post-war period marks the cessation of armed conflict entirely. Post–World War II Chronology of the post–World War II era The term "post-war" can have different meanings in different countries and refer to a period determined by local considerations based on the effect of the war there. Some examples of post-war events are (in chronological order) ;The Cold War (1947–1991) The Cold War was a geopolitical conflict between the capitalist and liberal democratic United States of America, the authoritarian and Communist Marxist–Leninist Union of Soviet So ...

Baltimore And Ohio Railroad
The Baltimore and Ohio Railroad was the first common carrier railroad and the oldest railroad in the United States, with its first section opening in 1830. Merchants from Baltimore, which had benefited to some extent from the construction of the National Road early in the century, wanted to do business with settlers crossing the Appalachian Mountains. The railroad faced competition from several existing and proposed enterprises, including the Albany-Schenectady Turnpike, built in 1797, the Erie Canal, which opened in 1825, and the Chesapeake and Ohio Canal. At first, the B&O was located entirely in the state of Maryland; its original line extending from the port of Baltimore west to Sandy Hook, Maryland, opened in 1834. There it connected with Harper's Ferry, first by boat, then by the Wager Bridge, across the Potomac River into Virginia, and also with the navigable Shenandoah River. Because of competition with the C&O Canal for trade with coal fields in western Maryland ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brooklyn Navy Yard
The Brooklyn Navy Yard (originally known as the New York Navy Yard) is a shipyard and industrial complex located in northwest Brooklyn in New York City, New York. The Navy Yard is located on the East River in Wallabout Bay, a semicircular bend of the river across from Corlears Hook in Manhattan. It is bounded by Navy Street to the west, Flushing Avenue to the south, Kent Avenue to the east, and the East River on the north. The site, which covers , is listed on the National Register of Historic Places. The Brooklyn Navy Yard was established in 1801. From the early 1810s through the 1960s, it was an active shipyard for the United States Navy, and was also known as the United States Naval Shipyard, Brooklyn and New York Naval Shipyard at various points in its history. The Brooklyn Navy Yard produced wooden ships for the U.S. Navy through the 1870s, and steel ships after the American Civil War in the 1860s. The Brooklyn Navy Yard has been expanded several times, and at its peak, i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mercury(II) Fulminate
Mercury(II) fulminate, or Hg(CNO)2, is a primary explosive. It is highly sensitive to friction, heat and shock and is mainly used as a trigger for other explosives in percussion caps and detonators. Mercury(II) cyanate, though its chemical formula is identical, has a different atomic arrangement; the cyanate and fulminate anions are isomers. First used as a priming composition in small copper caps beginning in the 1820s, mercury fulminate quickly replaced flints as a means to ignite black powder charges in muzzle-loading firearms. Later, during the late 19th century and most of the 20th century, mercury fulminate became widely used in primers for self-contained rifle and pistol ammunition; it was the only practical detonator for firing projectiles until the early 20th century. Mercury fulminate has the distinct advantage over potassium chlorate of being non-corrosive, but it is known to weaken with time, by decomposing into its constituent elements. The reduced mercury which re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Card Stock
Card stock, also called cover stock and pasteboard, is paper that is thicker and more durable than normal writing and printing paper, but thinner and more flexible than other forms of paperboard. Card stock is often used for business cards, postcards, playing cards, catalogue covers, scrapbooking, and other applications requiring more durability than regular paper gives. The surface usually is smooth; it may be textured, metallic, or glossy. When card stock is labeled cover stock, it often has a glossy coating on one or both sides (''C1S'' or ''C2S'', for "coated: one side" or "coated: two sides"); this is used especially in business cards and book covers. Measurements Most nations describe paper in terms of grammage—the weight in grams of one sheet of the paper measuring one square meter. Other people, especially in the United States, describe paper in terms of pound weight—the weight in pounds per ream (500 sheets) of the paper with a given area (based on histori ...

Eveready Battery Company
Eveready Battery Company, Inc. is an American manufacturer of electric battery brands ''Eveready'' and ''Energizer'', owned by Energizer Holdings. Its headquarters are located in St. Louis, Missouri. The predecessor company began in 1890 in New York and was renamed in 1905. Today, the company makes batteries in the United States and China and has production facilities around the world. History On January 10, 1899, American Electrical Novelty and Manufacturing Company obtained U.S. Patent No. 617,592 (filed 12 March 1898) from David Misell, an inventor. This "electric device" designed by Misell was powered by "D" batteries laid front-to-back in a paper tube with the light bulb and a rough brass reflector at the end. Misell, the inventor of the tubular hand-held "electric device" (flashlight), assigned his invention over to the American Electrical Novelty and Manufacturing Company owned by Conrad Hubert. In 1905, Hubert changed the name again to ''The American Ever Ready Comp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
