John Jacob Bausch
John Jacob Bausch (born Johann Jakob Bausch; July 25, 1830 – February 14, 1926) was a German-American maker of optical instruments who co-founded Bausch & Lomb (with Henry Lomb). Over six decades he transformed his small, local optical shop into a large-scale international enterprise, pioneering the American optical industry. Early years Bausch was born Johann Jakob Bausch to Georg Bausch, a baker, and his wife Anna Schmid, in Groß Süßen (today part of Süßen) in the Kingdom of Württemberg, then part of the German Confederation. At the age of eighteen he moved to Bern, Switzerland, where he worked as a lens grinder in an optical shop designing camera lenses. In 1850 he emigrated to the United States. Upon his arrival, he made his way to a German community in Buffalo, New York, but because of a cholera epidemic there he settled in Rochester, New York, and Anglicized his name to John Jacob. Business Development In 1853, Bausch opened a retail optical shop in Rochester. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Süßen
Süßen (or Süssen) is a town in the district of Göppingen in Baden-Württemberg in southern Germany. It is located on the river Fils 8 km east of Göppingen, near Stuttgart. History Süßen was first mentioned with the name of ''Siezun'' in the Lorsch codex in 1071. Großsüßen (Greater'' Süßen'') was at first in the possession of the count of Helfenstein, who, in 1382 pledged it to the city of Ulm. Kleinsüßen (Smaller ''Süßen''),though, was in the hands of the family Pappenheim. They inherited the land from the landlords of Bubenhofen. In the Mediatization in 1802, Großsüßen was given to Bavaria, but in 1810, the lands were given back, in an exchange contract to Württemberg. Kleinsüßen, though, was never Bavarian land. After the exchange, both places, Groß- and Kleinsüßen, were assigned under the Head Office of Geislingen. With the opening of the Fils Valley Railway and Süßen station in 1847, Kleinsüßen was connected to the public transportation. ...

Opera Glasses
Opera glasses, also known as theater binoculars or Galilean binoculars, are compact, low-power optical magnification devices, usually used at performance events, whose name is derived from traditional use of binoculars at opera performances. Magnification power below 5× is usually desired in these circumstances in order to minimize image shake and maintain a large enough field of view. A magnification of 3× is normally recommended. The design of many modern opera glasses of the ornamental variety is based on the popular lorgnettes of the 19th century. In addition to the more stereotypical binocular type, folding opera glasses were another common design. They were made mostly of metal and glass, with a leatherette cover for grip and color. Although folding glasses have existed in one form or another since the 1890s, they were perhaps most popular in the mid-20th Century and many from this era are marked "Made in Japan" or, less commonly, "Made in Occupied Japan". The design can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ray-Ban
Ray-Ban is an American-Italian brand of luxury sunglasses and eyeglasses created in 1936 by Bausch & Lomb. The brand is known for its Wayfarer and Aviator lines of sunglasses. In 1999, Bausch & Lomb sold the brand to Italian eyewear conglomerate Luxottica Group for a reported $640 million. History In 1929, US Army Air Corps Colonel John A. Macready worked with Bausch & Lomb, a Rochester, New York-based medical equipment manufacturer, to create aviation sunglasses that would reduce the distraction for pilots caused by the intense blue and white hues of the sky. Specifically, MacCready was concerned that pilots' goggles would fog up, greatly reducing visibility at high altitude. The prototype, created in 1936 and known as "Anti-Glare", had plastic frames and green lenses that could cut out the glare without obscuring vision. The name "Ray-Ban" was hence derived from the ability of these glasses to limit the ingress of either ultra-violet or infra-red rays of light. Impact-res ...

Torpedo
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface vessels, submarines/ submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large ships without the need of large guns, though ...

Periscopes
A periscope is an instrument for observation over, around or through an object, obstacle or condition that prevents direct line-of-sight observation from an observer's current position. In its simplest form, it consists of an outer case with mirrors at each end set parallel to each other at a 45° angle. This form of periscope, with the addition of two simple lenses, served for observation purposes in the trenches during World War I. Military personnel also use periscopes in some gun turrets and in armoured vehicles. More complex periscopes using prisms or advanced fiber optics instead of mirrors and providing magnification operate on submarines and in various fields of science. The overall design of the classical submarine periscope is very simple: two telescopes pointed into each other. If the two telescopes have different individual magnification, the difference between them causes an overall magnification or reduction. Early examples Johannes Hevelius described an earl ...

First World War
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microtome
A microtome (from the Greek ''mikros'', meaning "small", and ''temnein'', meaning "to cut") is a cutting tool used to produce extremely thin slices of material known as ''sections''. Important in science, microtomes are used in microscopy, allowing for the preparation of samples for observation under transmitted light or electron radiation. Microtomes use steel, glass or diamond blades depending upon the specimen being sliced and the desired thickness of the sections being cut. Steel blades are used to prepare histological sections of animal or plant tissues for light microscopy. Glass knives are used to slice sections for light microscopy and to slice very thin sections for electron microscopy. Industrial grade diamond knives are used to slice hard materials such as bone, teeth and tough plant matter for both light microscopy and for electron microscopy. Gem-quality diamond knives are also used for slicing thin sections for electron microscopy. Microtomy is a method for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philadelphia Centennial Exposition
The Centennial International Exhibition of 1876, the first official World's Fair to be held in the United States, was held in Philadelphia, Pennsylvania, from May 10 to November 10, 1876, to celebrate the 100th anniversary of the signing of the Declaration of Independence in Philadelphia. Officially named the International Exhibition of Arts, Manufactures, and Products of the Soil and Mine, it was held in Fairmount Park along the Schuylkill River on fairgrounds designed by Herman J. Schwarzmann. Nearly 10 million visitors attended the exposition, and 37 countries participated in it. Precursor The Great Central Fair on Logan Square in Philadelphia, Pennsylvania, in 1864 (also known as the Great Sanitary Fair), was one of the many United States Sanitary Commission's Sanitary Fairs held during the Civil War. They provided a creative and communal means for ordinary citizens to promote the welfare of Union soldiers and dedicate themselves to the survival of the nation, and the ...

Microscope
A microscope () is a laboratory instrument used to examine objects that are too small to be seen by the naked eye. Microscopy is the science of investigating small objects and structures using a microscope. Microscopic means being invisible to the eye unless aided by a microscope. There are many types of microscopes, and they may be grouped in different ways. One way is to describe the method an instrument uses to interact with a sample and produce images, either by sending a beam of light or electrons through a sample in its optical path, by detecting photon emissions from a sample, or by scanning across and a short distance from the surface of a sample using a probe. The most common microscope (and the first to be invented) is the optical microscope, which uses lenses to refract visible light that passed through a thinly sectioned sample to produce an observable image. Other major types of microscopes are the fluorescence microscope, electron microscope (both the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horn-rimmed Glasses
Horn-rimmed glasses are a type of eyeglasses. Originally made out of either horn or tortoise shell, for most of their history they have actually been constructed out of thick plastics designed to imitate those materials. They are characterized by their bold appearance on the wearer's face, in contrast to metal frames, which appear less pronounced. Horn-rimmed glasses were one of the first styles of eyeglasses to become a popular fashion item, after comedian Harold Lloyd began wearing a round pair in his films. The glasses have enjoyed various periods of popularity throughout the 20th century, being considered especially fashionable in the 1920s–1930s and in the 1950s–1960s in particular, while ceding to rimless and wire framed glasses during the 1970s and 1990s–2000s. Michael Caine's first appearance as Harry Palmer in '' The Ipcress File'' in 1965 featured his signature look of thick horn-rimmed glasses which made him a style icon of the 1960s. The style has brought a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
